Network Troubleshooting Interview Questions For Freshers

1) what is network troubleshooting.

Network troubleshooting is a methodical process that aims to troubleshoot problems and get the network working normally again within the parameters and network. Troubleshooting of a network can be performed manually or automatically.

2) What is a network?

A network is formed by connecting two or more devices so that they may exchange data. A network can be divided into subcategories based on its size, number of nodes, types of connections, functional links, topology, and purpose.

3) What is Troubleshooting?

Troubleshooting is the process of finding a problem, error, or fault in the software, a computer system, or any other device, making a plan to troubleshoot it, and putting the plan into action. It is possible to fix and restore a computer or software that is broken, won't work, or is acting strangely. 

Troubleshooting fixes a faulty system or application. It's a strategy with one or more steps, depending on the situation. First, identify the problem, then create a solution, and finally implement it.

4) What are the various network cables used in networking?

When it comes to networks, there are a few distinct kinds of cables that are typically used:

• Coaxial Cable
• Wireless LANs
• Fibre Optic Cable
• Shielded Twisted Pair (STP) Cable
• Cable Installation Guides
• Unshielded Twisted Pair (UTP) Cable

5) How would you troubleshoot DHCP server problems?

Verify that a system set up on the network can communicate with the DHCP server using an IP address. Verify that both the DHCP server and the DHCP client have their respective services started. Using Nmap, verify if the DHCP server can be accessed.

6) Identify three steps used to diagnose FTP server-related problems?

The three steps to troubleshoot problems with an FTP server are:

• Check with Nmap if the ports are accessible (20 and 21).
• Determine if a firewall is blocking server traffic. 
• Ping is used to test connectivity.

7) What are the most frequent network issues?

The following are the frequent problems with networks:-

• Cable Issue: A cable connecting two devices has the potential to malfunction, shorten, or be physically damaged.
• Software Issue: Due to problems with software compatibility and different versions, IP data packets can't get from the source to the destination.
• Connectivity Issue: A physical failure or malfunction of the device's specified port or interface could prevent data from being sent from the source host to the destination host.
• Network IP Issue: If the network's IP addresses, subnet masks, and next-hop router settings are incorrect, no data can go from the source to the destination IP address.

8) What are the steps for the network troubleshooting procedure?

Before you try to fix a problem, make sure you know what it is, how it happened, whom it affects, and how long it has been going on. Instead of wasting time on fixes that don't work, you'll have a much better chance of quickly troubleshooting the problem if you gather the necessary information and explain what's going on.

The steps to network troubleshooting are

• Check hardware
• Use ipconfig
• Use tracert and ping
• Perform a DNS check
• Contact the ISP
• Check antivirus software
• Review logs

9) What is a private IP address?

Exclusive usage of private IP addresses is permitted within private networks. 

These IPs are reserved for private intranets and are not reachable from the wider Internet. This prevents any internal network conflicts from occurring. Concurrently, since intranets cannot "see" each other, the same pool of private IP addresses can be used for several different ones.

10) What is Netstat utility?

This command is often used for incoming and outgoing connections, listening ports, routing tables, and tracking how often a program is used. 

Using the Netstat command, you can make graphs that show statistics about networks and protocols. In the form of a table, you can see the status of TCP and UDP endpoints and the routing table and interface information. 

11) What are the benefits of sharing an address?

Instead of routing, sharing addresses makes things safer. This is because private IP addresses on the internal network are not visible to host PCs on the Internet; only the public IP address of the external interface on the computer does address translation.

12) How many different types of TCP/IP layers?

There are four primary layers in TCP/IP:

• Transport Layer
• Application Layer
• Network Layer
• Internet Layer

13) What is the Ipconfig command, and why is it used?

The IPCONFIG command shows the IP address information for a computer. From the output, we can find the IP address, DNS IP address, and gateway IP address given to the computer.

14) How can an antivirus recover data?

You can get a new computer and load it with the latest OS and antivirus programs. Then, add the contaminated HDD to the computer as an additional disc. The backup HDD should then be wiped and scanned. The data migration to the new platform can now begin.

Network Troubleshooting Interview Questions For Experienced

15) what is network topology.

Network topology is how the devices or nodes of a network (like printers, computers, hubs, servers, routers, switches, Etc.) are connected to each other over a communication medium. 

It has two parts: 

• The physical topology, which is how the cables (the media) are set up, and 
• The logical topology, which shows how the hosts connect to the media.

16) What is the difference between a Workgroup and a Domain?

The key difference between a workgroup and a domain is that network administrators in a domain utilize servers to administer all of the computers that are part of the domain. 

However, in a workgroup, no one computer has authority over another computer in the group. In addition, devices that are part of a domain might be connected to a number of different local networks, but in a workgroup, all of the devices are members of the same local area network (LAN) or subnet.

17) Let's say a virtual machine is suddenly turned off. Which VM log files should be looked at to troubleshoot what's wrong?

If something like this happens, an administrator needs to analyze the issue by looking at the log files named vmware.log and hostd.log. 

The hostd.log log files explain the agent that maintains and configures the ESXi host and virtual machines. 

The Vmare.log log files keep track of the activity on the ESX host and the virtual machines it hosts.

18) What common problems with software can cause network problems?

Several of the following can contribute to network-related problems:

• Error in configuration
• Application conflicts
• Client-server problems
• Security issues
• Protocol mismatch
• User policy and rights issues

19) Why is encryption so important on a network?

Encryption is the procedure of transforming data into unintelligible code. The data is encrypted and then translated to its original format using a password or secret key. 

During a mid-stream interception, encrypted data would still be inaccessible without the appropriate password or key.

20) What would you do to troubleshoot what was wrong with an FTP server?

If you're having issues with your FTP server, here are the three things you should try:

• Ping is a simple tool for checking network connectivity. The "echo request" is a part of ICMP that is used by the "ping" command (Internet Control Message Protocol). To check if a device is online or active, you can use the "ping" command, equivalent to sending an echo request.
• Check the available ports with Nmap (20 and 21). You may evaluate your firewall and other security measures with the help of the Nmap-hosted security tool. Ports in modern operating systems are numeric addresses used for networking. As a general rule, various services make use of separate ports. It is essential to know which ports are open and closed to prevent any security breaches resulting from the improper port configuration.
• Find out if a firewall is preventing traffic from reaching the server.

21) What are the OSI Reference Models' layers? 

The seven levels that make up the OSI reference models are listed below:

• Physical Layer (Layer 1)
• Data Link Layer (Layer 2)
• Network Layer (Layer 3)
• Transport Layer (Layer 4)
• Session Layer (Layer 5)
• Presentation Layer (Layer 6)
• Application Layer (Layer 7)

22) How to troubleshoot IP-related problems?

If we are unable to communicate with the IP address of the destination and the TCP/IP protocol suite does not reveal a path to the next hop from any point in the network, we will make use of the PING and TRACEROUTE troubleshooting tools to determine the nature of the issue and its geographical origin.

23) What are the steps to troubleshoot IP-related network issues?

Here are some general steps for troubleshooting IP network problems that have to do with:

• The first step in troubleshooting a connectivity problem is pinpointing which devices are causing it between the source and destination hosts.
• Once you have discovered the devices using the tools, the failure could result from a physical connectivity issue. Therefore, you must check all the tethers and cables along the route.
• The LAN connectivity at your office may be malfunctioning. That's why you need to double-check your local area network. The source and the destination IP can't talk because the local port is faulty or unavailable.
• One possible source of the error is a problem with the router's connection to the network, as the data passes through several channels en route to the destination. Therefore, you should ensure the router is defined correctly for each intermediary hop.

24) What are the different types of a network? Explain each briefly.

There are four main categories of networks. Let's analyze each one separately.

• Personal Area Network (PAN): It is the most basic and simplest type of network and is often used at home. It's a link between the computer and something else, like a phone, printer, modem, tablet, Etc.
• Local Area Network (LAN): LANs are commonly seen in settings such as Internet cafes and smaller businesses. They are typically employed in networked file transfers and online game activity.
• Metropolitan Area Network (MAN): It has more power than LAN networks. MAN covers a small town, city, or other large areas. So much area has to be connected, so a big server is needed.
• Wide Area Network (WAN): It is more complicated than LAN and usually covers a large area and a long distance. WAN is not owned by just one organization; instead, it is owned by many different groups. The Internet is the biggest and most widespread WAN.

25) How are physical addresses and logical addresses different?

Logical Address: It's called an Ip Address (IPv4 -32 bit & IPv6 -128 bit)

Physical Address: It's called a MAC Address (48-bit)

26) What Is a Subnet Mask?

Specifying a network's identity is known as the subnet mask.

For Example:

• For a class A address, a standard subnet mask is 255.0.0.0,
• For a class B address, a common subnet mask is 255.255.0.0,
• For a class C address, a common subnet mask is 255.255.255.0.

27) What is the maximum allowable length of a UTP cable?

The maximum length for a single section of UTP cable can be installed between 90 and 100 meters. By using repeaters and switches, it is possible to circumvent this limitation.

28) What are the main elements of a protocol?

A protocol consists of three essential parts:

Advanced-Level Network Troubleshooting Interview Questions

29) what is an apipa ip address or, when the dhcp server isn't available, what ip address does the computer get.

Automatic private IP addressing is the acronym for this APIPA system.

Whenever a Dynamic Host Configuration Protocol (DHCP) server is not accessible, Windows clients automatically assign themselves IP addresses. IPv4 APIPA is the name given to this particular address. Hosts with IP addresses between 169.254.0.0 and 169.254.255.255

30) What is the difference between Firewall and Antivirus?

Firewall: A firewall prevents unauthorized users from entering a protected network. Malware such as viruses, spyware, and adware can easily be installed and has no defenses.

Antivirus: An antivirus program is designed to ward off any malware, adware, or viruses that might try to infiltrate your computer. These are both networking security applications.

31) How many different addresses are there in each class of Internet addresses?

Here are the five different ranges of Internet addresses:

• Class A: 0.0.0.0 – 127.255.255.255
• Class B: 128.0.0.0 – 191.255.255.255
• Class C: 192.0.0.0 – 223.255.255.255
• Class D: 224.0.0.0 – 239.255.255.255
• Class E: 240.0.0.0 – 247.255.255.255

32) What is HTTPS, and what port is it used for?

Secure HTTP is HTTPS. HTTPS is used to send and receive information over a computer network safely. HTTPs give websites authentication, which keeps unwanted attacks from happening.

Port 443 is used by TCP for HTTP. When two people are conversing back and forth, the HTTPs protocol encrypts the discussion so that the data can't be modified. With the help of an SSL certificate, it checks to see if the connection to the server that was asked for is reasonable.

33) What is meant by 127.0.0.1 and localhost?

The localhost or loopback address is 127.0.0.1. These systems are often only accessible to the largest clients or the Internet's founding members. Pinging the server to see if it responds is the first step in diagnosing connection problems.

There could be many reasons why the server isn't responding, such as a malfunctioning network, faulty wiring, or a malfunctioning network card. Pinging 127.0.0.1 indicates that the hardware is functioning properly because it is a loopback connection on the NIC.

With most network operations, 127.0.0.1 and localhost refer to the same thing.

34) What is the difference between the Intranet, Internet, and Extranet?

They both use TCP/IP technology, but the level of access each user has inside and outside of the network is different.

• Intranet: It only lets people in the same organization use it.
• Internet: Anyone from anywhere can use the web to get to applications.
• Extranet: Users from outside the organization are allowed to use the network application or are given access to it.

35) What are different ways to send data through networks?

In computer networks, there are three different ways that data can be sent. Here is a list of them,

• Simplex: Simplex is one-way data transport. Simplex mode transfers data from sender to receiver or receiver to sender—radio signal, computer-to-printer signal, Etc.
• Half Duplex: Both directions can transfer data, but not simultaneously. Data is sent and received. In internet browsing, a user submits a request to the server, which then sends back the web page.
• Full Duplex: Simultaneous bidirectional data transfer. Two-way highways, phone calls, Etc.

36) What is Ghost Imaging?

Ghost Imaging is a software-driven backup method commonly referred to as cloning. The contents of a hard disc are copied to another server in the form of a single compressed file or an image, a collection of files. It can also return a ghost picture to its initial condition if required. It is typically applied while reinstalling an operating system.

37) Which counters are used for debugging VM CPU performance issues?

Memory, central processing unit (CPU), and network utilization can be evaluated using the ESXTOP tool. VMware administrators will find it a beneficial tool when dealing with performance difficulties. 

To configure ESXTOP, you will require the vSphere Client and putty and SSH sessions. To evaluate the performance of the CPU, we utilize the counters percent MLMTD, RDY, and CSTP.

38) What are the various aspects that affect a network's performance?

A network's performance efficiency can be affected by the following:

• Transmission medium types
• A large number of users

39) What are the different types of networks?

There are two different types of networks available they are:

• Server-based network: It allows for the management and protection of a network to be centralized on a small number of computers known as "servers."
• Peer-to-peer network: Computers can function in two roles: the server providing access to shared resources and the client making use of those resources.

40) What's the difference between FTP and TFTP application layer protocols?

The simple file transfer protocol (TFTP) describes a local host retrieving data from a remote host. It takes advantage of the standard packet delivery features of UDP. However, it is unreliable and lacks security.

TCP/IP often provides the File Transfer Protocol to transfer data between hosts (FTP). Because it takes advantage of TCP's facilities, it is dependable and safe. Two connections are established between the hosts: one for command and control information and another for actual data transfer.

41) How can you tell what IP class a particular IP address belongs to?

Class A, B, and C, IP addresses can be determined by inspecting the address's first octet. Class A addresses have a leading zero bit in the first octet. Class B addresses start with the bit position 10. When the prefix is 110, you know you're dealing with a Class C system.

42) What are proxy servers, and how do they keep networks safe?

The primary purpose of proxy servers is to prevent users from the outside world from identifying the IP addresses of a private network. Even the physical location of the network can only be determined if the correct IP address can be provided. Proxy servers can render a network almost completely invisible to users outside it.

Most Common Network Troubleshooting FAQs

1) what is the basic troubleshooting in networking.

Network troubleshooting is a repeatable process, it can be broken down into simple steps that anyone can follow.

• Identify the Problem
• Develop a Theory
• Test the Theory
• Plan of Action
• Implement the Solution
• Verify System Functionality
• Document the Issue

2) Which tool is used for network troubleshooting?

The ICMP ping tool is a basic network troubleshooting tool that allows you to determine whether or not a device is reachable on the network. It logs errors such as packet loss, round-trip time, and so on.

3) What are the 10 common network problems?

The top 10 common network issues are as follows:

• High Bandwidth Usage
• Large Downloads
• IP Address Exhaustion
• File Sharing
• High CPU Usage

Simply enter the ping command in the command prompt on a Windows system, followed by the hostname or URL. Enter the same command in the terminal for Linux systems. Remember that the command syntax is as follows:

Syntax: ping hostname

5) How do I troubleshoot TCP IP?

The steps to troubleshoot TCP/IP issues are as follows.

Step 1: Check the configuration

Step 2: Networking traces

Step 3: Ping the computer's local IP address

Step 4: Troubleshoot error messages that appear during the ping or telnet test.

Step 5: Telnet or Ping to the default gateway

Step 6: Check issues that relate to the particular destination node

6) What are the causes of network failure?

Of course, these types of network interview questions answer themselves, but it also allows you to talk through your journey. Some interviewers will be looking for a certain level of experience, potentially 5-10 years, for more senior network engineer jobs. An interviewer may look for relevant work experience for entry-level network engineer jobs, such as an IT support role or other qualifications. However, this should all be specified in the network engineer job description you applied for.

5. What is your preferred area of expertise within network engineering?

As mentioned, throughout the interview, you should keep referring back to the specific network engineering job you’re interviewing for. However, many employers will want you to have either some experience or awareness of all aspects of network engineering. So, when answering this question, mention all the areas of network engineering you have knowledge and experience in and your preferred area you specialise in. 

If you’re looking for network engineer interview preparation for these questions, here’s how you could respond:

“While I find every aspect of being a network engineer enjoyable, there is one particular area where my passion and expertise truly shine when I interact with clients and support with troubleshooting their server issues. I love the challenge of dealing with server and configuration problems and coming up with solutions that allow the client to get the most out of the network they’re using.”

6. Why did you apply for this particular network engineer job?

Network engineer interview questions and answers like this require you to research the potential employer to genuinely understand the organisation's mission, vision, and values. You probably did this before applying for the role, but refreshing your memory to prepare a response to this question would be a smart move. 

Here's how to prepare for network engineer interview questions like this:

"I'm really eager to take on this network engineering job and be a part of what looks like a creative and collaborative team. The prospect of engaging in some of the projects you've worked on excites me and is something I'm motivated and ready to be a part of. I genuinely believe this environment will enable me to make a more significant impact and forge meaningful connections in my network engineering career."

7. What network engineering skills do you possess?

10. How would you manage multiple networking projects? 

Network engineers are known for their time management and organisational skills and typically have the ability to manage multiple projects at once while organising their workload independently and meeting the goals of their employer or clients they work with. 

So, when asked this type of question, here’s how you could respond:

"With my experience as a network engineer, managing multiple projects has become second nature to me. I rely on a project management programme to ensure my workload and various projects are completed on time and within budget. I take this approach as it allows me to keep on top of all my deadlines and meet the needs of the business and end users' needs."

The ability to manage multiple projects is also a transferable skill applicable to other professions. So if you’re coming into network engineering from a different background, you can still answer this question but specify where you gained your experience. 

11. Tell us about the biggest network you’ve engineered

Interviewers will typically ask these types of network engineer interview questions as they'll want to know if you have experience designing, implementing and troubleshooting networks similar to or the same size as the networks they and their clients use. 

When it comes to these types of network engineer interview questions and answers, here's an example of a response you could give:

“Among the networks I've designed, implemented, and provided troubleshooting support on, the biggest one I worked on was with my former employer. This project involved interconnecting numerous locations across the country, providing seamless communication for their employees working both onsite and remotely around the world - the latter of which involved me setting up secure VPNs to enable safe access to the network from remote locations.”

Even if you have yet to work on networks of the same scale, this won't necessarily mean you won't fit the employer's requirements. Your enthusiasm and other credentials will always be taken into account. 

12. How would you go about troubleshooting an issue with a network?

Troubleshooting issues is a common responsibility of network engineer jobs.

Top 20 Problem Solving Interview Questions (Example Answers Included)

Mike Simpson 0 Comments

By Mike Simpson

When candidates prepare for interviews, they usually focus on highlighting their leadership, communication, teamwork, and similar crucial soft skills . However, not everyone gets ready for problem-solving interview questions. And that can be a big mistake.

Problem-solving is relevant to nearly any job on the planet. Yes, it’s more prevalent in certain industries, but it’s helpful almost everywhere.

Regardless of the role you want to land, you may be asked to provide problem-solving examples or describe how you would deal with specific situations. That’s why being ready to showcase your problem-solving skills is so vital.

If you aren’t sure who to tackle problem-solving questions, don’t worry, we have your back. Come with us as we explore this exciting part of the interview process, as well as some problem-solving interview questions and example answers.

What Is Problem-Solving?

When you’re trying to land a position, there’s a good chance you’ll face some problem-solving interview questions. But what exactly is problem-solving? And why is it so important to hiring managers?

Well, the good folks at Merriam-Webster define problem-solving as “the process or act of finding a solution to a problem.” While that may seem like common sense, there’s a critical part to that definition that should catch your eye.

What part is that? The word “process.”

In the end, problem-solving is an activity. It’s your ability to take appropriate steps to find answers, determine how to proceed, or otherwise overcome the challenge.

Being great at it usually means having a range of helpful problem-solving skills and traits. Research, diligence, patience, attention-to-detail , collaboration… they can all play a role. So can analytical thinking , creativity, and open-mindedness.

But why do hiring managers worry about your problem-solving skills? Well, mainly, because every job comes with its fair share of problems.

While problem-solving is relevant to scientific, technical, legal, medical, and a whole slew of other careers. It helps you overcome challenges and deal with the unexpected. It plays a role in troubleshooting and innovation. That’s why it matters to hiring managers.

How to Answer Problem-Solving Interview Questions

Okay, before we get to our examples, let’s take a quick second to talk about strategy. Knowing how to answer problem-solving interview questions is crucial. Why? Because the hiring manager might ask you something that you don’t anticipate.

Problem-solving interview questions are all about seeing how you think. As a result, they can be a bit… unconventional.

These aren’t your run-of-the-mill job interview questions . Instead, they are tricky behavioral interview questions . After all, the goal is to find out how you approach problem-solving, so most are going to feature scenarios, brainteasers, or something similar.

So, having a great strategy means knowing how to deal with behavioral questions. Luckily, there are a couple of tools that can help.

First, when it comes to the classic approach to behavioral interview questions, look no further than the STAR Method . With the STAR method, you learn how to turn your answers into captivating stories. This makes your responses tons more engaging, ensuring you keep the hiring manager’s attention from beginning to end.

Now, should you stop with the STAR Method? Of course not. If you want to take your answers to the next level, spend some time with the Tailoring Method , too.

With the Tailoring Method, it’s all about relevance. So, if you get a chance to choose an example that demonstrates your problem-solving skills, this is really the way to go.

Top 3 Problem-Solving-Based Interview Questions

Alright, here is what you’ve been waiting for: the problem-solving questions and sample answers.

While many questions in this category are job-specific, these tend to apply to nearly any job. That means there’s a good chance you’ll come across them at some point in your career, making them a great starting point when you’re practicing for an interview.

So, let’s dive in, shall we? Here’s a look at the top three problem-solving interview questions and example responses.

1. Can you tell me about a time when you had to solve a challenging problem?

In the land of problem-solving questions, this one might be your best-case scenario. It lets you choose your own problem-solving examples to highlight, putting you in complete control.

When you choose an example, go with one that is relevant to what you’ll face in the role. The closer the match, the better the answer is in the eyes of the hiring manager.

EXAMPLE ANSWER:

“While working as a mobile telecom support specialist for a large organization, we had to transition our MDM service from one vendor to another within 45 days. This personally physically handling 500 devices within the agency. Devices had to be gathered from the headquarters and satellite offices, which were located all across the state, something that was challenging even without the tight deadline. I approached the situation by identifying the location assignment of all personnel within the organization, enabling me to estimate transit times for receiving the devices. Next, I timed out how many devices I could personally update in a day. Together, this allowed me to create a general timeline. After that, I coordinated with each location, both expressing the urgency of adhering to deadlines and scheduling bulk shipping options. While there were occasional bouts of resistance, I worked with location leaders to calm concerns and facilitate action. While performing all of the updates was daunting, my approach to organizing the event made it a success. Ultimately, the entire transition was finished five days before the deadline, exceeding the expectations of many.”

2. Describe a time where you made a mistake. What did you do to fix it?

While this might not look like it’s based on problem-solving on the surface, it actually is. When you make a mistake, it creates a challenge, one you have to work your way through. At a minimum, it’s an opportunity to highlight problem-solving skills, even if you don’t address the topic directly.

When you choose an example, you want to go with a situation where the end was positive. However, the issue still has to be significant, causing something negative to happen in the moment that you, ideally, overcame.

“When I first began in a supervisory role, I had trouble setting down my individual contributor hat. I tried to keep up with my past duties while also taking on the responsibilities of my new role. As a result, I began rushing and introduced an error into the code of the software my team was updating. The error led to a memory leak. We became aware of the issue when the performance was hindered, though we didn’t immediately know the cause. I dove back into the code, reviewing recent changes, and, ultimately, determined the issue was a mistake on my end. When I made that discovery, I took several steps. First, I let my team know that the error was mine and let them know its nature. Second, I worked with my team to correct the issue, resolving the memory leak. Finally, I took this as a lesson about delegation. I began assigning work to my team more effectively, a move that allowed me to excel as a manager and help them thrive as contributors. It was a crucial learning moment, one that I have valued every day since.”

3. If you identify a potential risk in a project, what steps do you take to prevent it?

Yes, this is also a problem-solving question. The difference is, with this one, it’s not about fixing an issue; it’s about stopping it from happening. Still, you use problem-solving skills along the way, so it falls in this question category.

If you can, use an example of a moment when you mitigated risk in the past. If you haven’t had that opportunity, approach it theoretically, discussing the steps you would take to prevent an issue from developing.

“If I identify a potential risk in a project, my first step is to assess the various factors that could lead to a poor outcome. Prevention requires analysis. Ensuring I fully understand what can trigger the undesired event creates the right foundation, allowing me to figure out how to reduce the likelihood of those events occurring. Once I have the right level of understanding, I come up with a mitigation plan. Exactly what this includes varies depending on the nature of the issue, though it usually involves various steps and checks designed to monitor the project as it progresses to spot paths that may make the problem more likely to happen. I find this approach effective as it combines knowledge and ongoing vigilance. That way, if the project begins to head into risky territory, I can correct its trajectory.”

17 More Problem-Solving-Based Interview Questions

In the world of problem-solving questions, some apply to a wide range of jobs, while others are more niche. For example, customer service reps and IT helpdesk professionals both encounter challenges, but not usually the same kind.

As a result, some of the questions in this list may be more relevant to certain careers than others. However, they all give you insights into what this kind of question looks like, making them worth reviewing.

Here are 17 more problem-solving interview questions you might face off against during your job search:

• How would you describe your problem-solving skills?
• Can you tell me about a time when you had to use creativity to deal with an obstacle?
• Describe a time when you discovered an unmet customer need while assisting a customer and found a way to meet it.
• If you were faced with an upset customer, how would you diffuse the situation?
• Tell me about a time when you had to troubleshoot a complex issue.
• Imagine you were overseeing a project and needed a particular item. You have two choices of vendors: one that can deliver on time but would be over budget, and one that’s under budget but would deliver one week later than you need it. How do you figure out which approach to use?
• Your manager wants to upgrade a tool you regularly use for your job and wants your recommendation. How do you formulate one?
• A supplier has said that an item you need for a project isn’t going to be delivered as scheduled, something that would cause your project to fall behind schedule. What do you do to try and keep the timeline on target?
• Can you share an example of a moment where you encountered a unique problem you and your colleagues had never seen before? How did you figure out what to do?
• Imagine you were scheduled to give a presentation with a colleague, and your colleague called in sick right before it was set to begin. What would you do?

15 Common Problem-Solving Interview Questions

In an interview for a big tech company, I was asked if I’d ever resolved a fight — and the exact way I went about handling it. I felt blindsided, and I stammered my way through an excuse of an answer.

It’s a familiar scenario to fellow technical job seekers — and one that risks leaving a sour taste in our mouths. As candidate experience becomes an increasingly critical component of the hiring process, recruiters need to ensure the problem-solving interview questions they prepare don’t dissuade talent in the first place. 

Interview questions designed to gauge a candidate’s problem-solving skills are more often than not challenging and vague. Assessing a multifaceted skill like problem solving is tricky — a good problem solver owns the full solution and result, researches well, solves creatively and takes action proactively. 

It’s hard to establish an effective way to measure such a skill. But it’s not impossible.

We recommend taking an informed and prepared approach to testing candidates’ problem-solving skills . With that in mind, here’s a list of a few common problem-solving interview questions, the science behind them — and how you can go about administering your own problem-solving questions with the unique challenges of your organization in mind.

Key Takeaways for Effective Problem-Solving Interview Questions

• Problem solving lies at the heart of programming. 
• Testing a candidate’s problem-solving skills goes beyond the IDE. Problem-solving interview questions should test both technical skills and soft skills.
• STAR, SOAR and PREP are methods a candidate can use to answer some non-technical problem-solving interview questions.
• Generic problem-solving interview questions go a long way in gauging a candidate’s fit. But you can go one step further by customizing them according to your company’s service, product, vision, and culture. 

Technical Problem-Solving Interview Question Examples

Evaluating a candidates’ problem-solving skills while using coding challenges might seem intimidating. The secret is that coding challenges test many things at the same time — like the candidate’s knowledge of data structures and algorithms, clean code practices, and proficiency in specific programming languages, to name a few examples.

Problem solving itself might at first seem like it’s taking a back seat. But technical problem solving lies at the heart of programming, and most coding questions are designed to test a candidate’s problem-solving abilities.

Here are a few examples of technical problem-solving questions:

1. Mini-Max Sum  

This well-known challenge, which asks the interviewee to find the maximum and minimum sum among an array of given numbers, is based on a basic but important programming concept called sorting, as well as integer overflow. It tests the candidate’s observational skills, and the answer should elicit a logical, ad-hoc solution.

2. Organizing Containers of Balls  

This problem tests the candidate’s knowledge of a variety of programming concepts, like 2D arrays, sorting and iteration. Organizing colored balls in containers based on various conditions is a common question asked in competitive examinations and job interviews, because it’s an effective way to test multiple facets of a candidate’s problem-solving skills.

3. Build a Palindrome

This is a tough problem to crack, and the candidate’s knowledge of concepts like strings and dynamic programming plays a significant role in solving this challenge. This problem-solving example tests the candidate’s ability to think on their feet as well as their ability to write clean, optimized code.

4. Subarray Division

Based on a technique used for searching pairs in a sorted array ( called the “two pointers” technique ), this problem can be solved in just a few lines and judges the candidate’s ability to optimize (as well as basic mathematical skills).

5. The Grid Search 

This is a problem of moderate difficulty and tests the candidate’s knowledge of strings and searching algorithms, the latter of which is regularly tested in developer interviews across all levels.

Common Non-Technical Problem-Solving Interview Questions 

Testing a candidate’s problem-solving skills goes beyond the IDE . Everyday situations can help illustrate competency, so here are a few questions that focus on past experiences and hypothetical situations to help interviewers gauge problem-solving skills.

1. Given the problem of selecting a new tool to invest in, where and how would you begin this task? 

Key Insight : This question offers insight into the candidate’s research skills. Ideally, they would begin by identifying the problem, interviewing stakeholders, gathering insights from the team, and researching what tools exist to best solve for the team’s challenges and goals. 

2. Have you ever recognized a potential problem and addressed it before it occurred? 

Key Insight: Prevention is often better than cure. The ability to recognize a problem before it occurs takes intuition and an understanding of business needs. 

3. A teammate on a time-sensitive project confesses that he’s made a mistake, and it’s putting your team at risk of missing key deadlines. How would you respond?

Key Insight: Sometimes, all the preparation in the world still won’t stop a mishap. Thinking on your feet and managing stress are skills that this question attempts to unearth. Like any other skill, they can be cultivated through practice.

4. Tell me about a time you used a unique problem-solving approach. 

Key Insight: Creativity can manifest in many ways, including original or novel ways to tackle a problem. Methods like the 10X approach and reverse brainstorming are a couple of unique approaches to problem solving. 

5. Have you ever broken rules for the “greater good?” If yes, can you walk me through the situation?

Key Insight: “Ask for forgiveness, not for permission.” It’s unconventional, but in some situations, it may be the mindset needed to drive a solution to a problem.

6. Tell me about a weakness you overcame at work, and the approach you took. 

Key Insight: According to Compass Partnership , “self-awareness allows us to understand how and why we respond in certain situations, giving us the opportunity to take charge of these responses.” It’s easy to get overwhelmed when faced with a problem. Candidates showing high levels of self-awareness are positioned to handle it well.

7. Have you ever owned up to a mistake at work? Can you tell me about it?

Key Insight: Everybody makes mistakes. But owning up to them can be tough, especially at a workplace. Not only does it take courage, but it also requires honesty and a willingness to improve, all signs of 1) a reliable employee and 2) an effective problem solver.

8. How would you approach working with an upset customer?

Key Insight: With the rise of empathy-driven development and more companies choosing to bridge the gap between users and engineers, today’s tech teams speak directly with customers more frequently than ever before. This question brings to light the candidate’s interpersonal skills in a client-facing environment.

9. Have you ever had to solve a problem on your own, but needed to ask for additional help? How did you go about it? 

Key Insight: Knowing when you need assistance to complete a task or address a situation is an important quality to have while problem solving. This questions helps the interviewer get a sense of the candidate’s ability to navigate those waters. 

10. Let’s say you disagree with your colleague on how to move forward with a project. How would you go about resolving the disagreement?

Key Insight: Conflict resolution is an extremely handy skill for any employee to have; an ideal answer to this question might contain a brief explanation of the conflict or situation, the role played by the candidate and the steps taken by them to arrive at a positive resolution or outcome. 

Strategies for Answering Problem-Solving Questions

If you’re a job seeker, chances are you’ll encounter this style of question in your various interview experiences. While problem-solving interview questions may appear simple, they can be easy to fumble — leaving the interviewer without a clear solution or outcome. 

It’s important to approach such questions in a structured manner. Here are a few tried-and-true methods to employ in your next problem-solving interview.

1. Shine in Interviews With the STAR Method

S ituation, T ask, A ction, and R esult is a great method that can be employed to answer a problem-solving or behavioral interview question. Here’s a breakdown of these steps:

• Situation : A good way to address almost any interview question is to lay out and define the situation and circumstances. 
• Task : Define the problem or goal that needs to be addressed. Coding questions are often multifaceted, so this step is particularly important when answering technical problem-solving questions.
• Action : How did you go about solving the problem? Try to be as specific as possible, and state your plan in steps if you can.
• Result : Wrap it up by stating the outcome achieved. 

2. Rise above difficult questions using the SOAR method

A very similar approach to the STAR method, SOAR stands for S ituation, O bstacle, A ction, and R esults .

• Situation: Explain the state of affairs. It’s important to steer clear of stating any personal opinions in this step; focus on the facts.
• Obstacle: State the challenge or problem you faced.
• Action: Detail carefully how you went about overcoming this obstacle.
• Result: What was the end result? Apart from overcoming the obstacle, did you achieve anything else? What did you learn in the process? 

3. Do It the PREP Way

Traditionally used as a method to make effective presentations, the P oint, R eason, E xample, P oint method can also be used to answer problem-solving interview questions.  

• Point : State the solution in plain terms. 
• Reasons: Follow up the solution by detailing your case — and include any data or insights that support your solution. 
• Example: In addition to objective data and insights, drive your answer home by contextualizing the solution in a real-world example.
• Point : Reiterate the solution to make it come full circle.

How to Customize Problem-Solving Interview Questions 

Generic problem-solving interview questions go a long way in gauging a candidate’s skill level, but recruiters can go one step further by customizing these problem-solving questions according to their company’s service, product, vision, or culture. 

Here are some tips to do so:

• Break down the job’s responsibilities into smaller tasks. Job descriptions may contain ambiguous responsibilities like “manage team projects effectively.” To formulate an effective problem-solving question, envision what this task might look like in a real-world context and develop a question around it.  
• Tailor questions to the role at hand. Apart from making for an effective problem-solving question, it gives the candidate the impression you’re an informed technical recruiter. For example, an engineer will likely have attended many scrums. So, a good question to ask is: “Suppose you notice your scrums are turning unproductive. How would you go about addressing this?”

I believe in continuous learning, so I’d also provide resources for further reading and be available for any questions or clarifications.”

25. Can you discuss your experience with IP addressing and subnetting?

Deep in the heart of any network support technician’s role lies the understanding and manipulation of IP addresses and subnets. These elements are fundamental to how networks function and are organized. Therefore, your potential employer is keen to know the depth of your experience with these critical aspects of network operations. Can you troubleshoot IP address conflicts? Can you design and implement subnets effectively? These capabilities are key to ensuring the smooth operation of a company’s network infrastructure.

Example: “I have extensive experience with IP addressing and subnetting. I’ve worked with both IPv4 and IPv6 protocols, including the configuration of static and dynamic IPs.

In terms of subnetting, I’m proficient in breaking down larger networks into smaller subnets to improve efficiency and security. This includes calculating subnet masks, determining network and broadcast addresses, and understanding CIDR notation.

My exposure to real-world scenarios has allowed me to troubleshoot common issues related to IP conflicts and misconfigured subnets. I am also familiar with tools like ping, traceroute, and ipconfig for diagnosing network problems.”

26. How would you handle a situation where a critical network device fails?

As a network support technician, you’re the first line of defense against network failures. These can lead to significant downtime, which can be costly for businesses. Therefore, interviewers want to understand your approach to problem-solving under pressure, your knowledge in identifying and fixing the issue, and your ability to minimize disruption in such scenarios. They also want to see if you can communicate effectively with other team members or clients about the problem and how you’re addressing it.

Example: “In handling a critical network device failure, I would first isolate the issue to determine if it’s a hardware or software problem. If it’s a hardware issue, I’d replace the faulty device immediately with a spare one.

For software issues, I would troubleshoot using diagnostic tools and logs to identify the cause of the failure. Once identified, I’d apply the necessary fixes or patches.

During this process, communication is key. I would ensure all relevant parties are informed about the situation and estimated recovery time.

Finally, once resolved, I would document the incident, detailing the cause of the failure and steps taken to resolve it, for future reference and learning.”

27. What steps would you take to ensure a network is scalable as a company grows?

As technology continues to evolve, so does the need for a company’s network to adapt and expand. A network that is not scalable can hinder a company’s growth and productivity. The question is designed to assess your foresight, planning skills, and understanding of network infrastructure. It’s about ensuring you can provide a network that’s flexible and adaptable to the ever-changing needs of a growing business.

Example: “To ensure network scalability, I would start by designing a modular network. This allows for easy expansion and modification as the company grows.

Next, implementing virtualization can be beneficial. It provides flexibility in managing resources and handling increased traffic or data loads.

I’d also consider cloud-based solutions which offer scalable options to handle growth without significant infrastructure investment.

Lastly, regular monitoring of network performance is crucial. This helps identify potential bottlenecks early on and allows us to make necessary adjustments before they become problematic.”

28. Can you explain how you would set up a secure remote access for employees?

This question is designed to test two key skills for a Network Support Technician: technical knowledge and communication ability. Secure remote access is a critical part of many businesses, particularly with the rise of remote work. Therefore, employers want to ensure you have the technical expertise to set up such systems. Additionally, they’re interested in your ability to explain complex technical concepts in a way that non-technical stakeholders can understand, as this is often a key part of the role.

Example: “To set up secure remote access, I would first implement a Virtual Private Network (VPN) to create an encrypted connection over the internet. This ensures data transmitted between the remote user and the network is secure.

Next, I would enforce strong authentication methods like two-factor or multi-factor authentication. This adds an extra layer of security by requiring users to provide more than one piece of evidence to verify their identity.

Lastly, I would apply the principle of least privilege (PoLP), granting employees only the necessary access rights to perform their jobs. Regular audits should also be conducted to ensure compliance with these policies.”

29. How have you handled a situation where you had to work with a difficult team member to resolve a network issue?

Working in network support doesn’t only involve technical skills, but also requires strong interpersonal skills. This is particularly important when you’re part of a team where collaboration and communication are key. The question is meant to gauge your ability to navigate team dynamics, manage conflicts, and still get the job done efficiently. It helps the interviewer understand your problem-solving skills and how you handle challenging social situations in a professional setting.

Example: “In a previous team, we had a complex network issue that required everyone’s cooperation. One member was difficult to work with due to their lack of communication.

I approached the situation by first understanding their perspective and then clearly explaining how crucial their input was for resolution. I also established regular check-ins to ensure they felt involved and heard throughout the process.

This approach improved our collaboration and we were able to resolve the issue effectively. It taught me the importance of open communication and empathy in teamwork.”

30. Can you describe your approach to documenting network issues and their resolutions?

Documentation is a critical component of network support. It provides a record of what’s been done, which can prove invaluable for future troubleshooting, training, and demonstrating compliance with regulations. If you’re applying for a network support position, the hiring manager wants to know that you understand the importance of thorough, accurate documentation and have a system in place for doing it effectively.

Example: “I believe in a systematic approach to documenting network issues and their resolutions. Initially, I document the problem’s details including symptoms, error messages, and user reports. Then, I note down the troubleshooting steps taken along with their results.

Post-resolution, I record the final solution applied, ensuring it is detailed enough for future reference. This includes any changes made to configurations or hardware.

For effective knowledge sharing, I utilize tools like ticketing systems and databases. These records are crucial for recurring problems and provide valuable insights for improving the network infrastructure.”

Introduction

It is a popular notion that if you do not encounter any hurdles or problems in your efforts to keep your business running well, something is wrong. That is how issues in the workplace are unavoidable.

Today's businesses are increasingly reliant on IT techniques. Unfortunately, many firms do not devote enough attention to IT issues that may have an impact on their business processes and security. Taking a few simple steps can assist solve a range of problems while also reducing risks, downtime, and troubleshooting.

What is Troubleshooting?

The process of discovering, planning, and resolving a problem, error, or fault in the software, computer system or any other device is known as troubleshooting. When a computer or software becomes faulty, unresponsive, or behaves abnormally, it can be repaired and restored. Troubleshooting is used to keep a system or software in the desired state, particularly when it encounters or exhibits a problem. It is a methodical strategy that is carried out in one or more phases, depending on the problem's complexity. Identifying the problem is usually the first stage, followed by devising a solution to address the issue and finally putting that solution into action. However, there may be multiple causes for the problem, necessitating a more involved treatment.

Troubleshooting Interview Questions for Freshers

1. mention some common networking issues..

Some common networking issues are:

• Problem with the cable : The cable that connects two devices can become defective, shorter, or physically damaged.
• Connectivity Issue : The port or interface to which the device is attached or configured may be physically down or malfunctioning, preventing communication between the source and destination hosts.
• Incorrect configurations : Network faults and service disruptions can occur as a result of incorrect configuration, IP looping, routing problems, and other configuration difficulties.
• Software Issue : The transmission of IP data packets between the source and destination is disrupted due to software compatibility difficulties and version mismatches.
• Traffic overload : When a network (or a portion of a network) or a network node is overburdened with data, this is known as network congestion. Every network has a limit on the amount of data it can manage. This capacity establishes a limit on how much bandwidth and traffic your network can handle before performance suffers.
• Network IP problems : The source will be unable to reach the target IP over the network due to poor configuration of IP addresses, subnet masks, and routing IP to the next hop.

2. Define the Network Troubleshooting Procedure.

The combined measurements and processes used to discover, diagnose, and address problems in a computer network are referred to as network troubleshooting. It's a logical procedure used by network engineers to address network issues and increase network performance.

Before you begin troubleshooting any problem, you should have a clear grasp of what the issue is, how it arose, who it affects, and how long it has been present. You'll have a far higher chance of addressing the problem quickly if you acquire the proper facts and clarify the problem, rather than wasting time on useless fixes. To assist diagnose and fixing the issue, you can always start troubleshooting with these simple network troubleshooting procedures.

• Hardware Inspection : To begin, inspect the hardware that is installed on a computer, server, laptop, or other similar devices to ensure that it is connected, switched on, and operational. Sometimes the issue is as simple as a loose cord, a router that has shut down, or an unplugged cord; in these circumstances, network troubleshooting is unnecessary. Other basic methods for debugging network hardware can be followed. Perhaps turning the gadget on and off or leaving it off for sixty seconds will cure the problem. Cycling at a high intensity is also a good way to do so.
• Ipconfig: Ipconfig can be used to display TCP/IP network configuration values, discard a device's current IP and DHCP settings, and refresh a device's DHCP settings. Type ipconfig into the terminal from the command prompt. You may get your default gateway and IP address, but if it starts with 169, it won't get a genuine IP address. In some circumstances, using "ipconfig/renew" to request a new one would solve the problem. If you acquire your IP address through an ethernet cable, the problem is with the router rather than the network.
• Ping and Tracert: The "ping" command lets you send a signal to another device, which, if it is operational, will respond with a response to the sender. The "ping" command employs a "echo request," which is a component of the ICMP (Internet Control Message Protocol). When you ping a device, you're sending out an echo request, and you'll get an echo back if the device is active or online. Tracert command displays all of a packet's steps on its way to its destination. If the IP address is correct without ethernet, the issue is most likely between your router and the internet. This is the moment to use ping to check if larger servers can connect to your router. If this is unable to connect to your router, there may be an issue. Tracert, which bounces between your router and server’s DNS, can also be used to track the problem. We can pinpoint the exact site of the issue, and if the error occurs early, the issue may be with your local network.
• DNS Check: Use nslookup command to see if the server you're using has any issues. The nslookup command retrieves DNS records for a domain name or an IP address. Remember that DNS servers contain IP addresses and domain names, therefore the nslookup command allows you to query DNS records for information. If you see terms like "timed out," "service failure," "refused," or "network is unreachable" on your screen, the issue is with the DNS rather than your network. To find the precise IP address(es) associated with a domain name, use the nslookup command. There is a DNS problem if this utility is unable to resolve this information. Along with simple lookup, the nslookup tool can query specific DNS servers to discover if there is a problem with the host's default DNS servers.
• ISP (Internet Service Provider) contact: Contact your internet service provider if you have any problems with your internet service. Perhaps there is a problem on their end. You can also use the mobile apps to see if other people are experiencing the same issues by looking up outage maps and associated information.
• Malware and Viruses Check: Malware and Viruses Check is done to see if something is preventing some programs from connecting to the network and running properly. This could be because your antivirus software isn't up to date, or the network is experiencing issues that are being blocked by it.
• Database logs: Checks for faults in your database and database connections if it isn't performing properly. Perhaps it is not working as it should, causing difficulties to spread and the network to slow down.

3. What is the difference between a Router, a Switch, and a Hub?

• Hubs, also known as repeaters, are network devices that operate on layer 1 (the physical layer) to connect network devices for communication.
• A hub is a basic and inexpensive networking device that connects a group of computers to a single network. When a hub receives a data packet (an Ethernet frame) at one of its ports, it broadcasts (repeats) the packet to all of its ports, which includes all other network devices. When two network devices on the same network try to send packets at the same time, a collision occurs.
• Hub is  a network monitoring tool. They're also employed to give connectivity in businesses. It can be used to create a device that can be accessed from anywhere on the network.
• Switches are network devices that communicate at the OSI model's layer 2 (data link layer) Switches are also known as intelligent hubs. A device in a network that filters and forwards packets between LAN segments is a switch.  Switches work at the data connection layer (layer 2) of the OSI Reference Model, as well as the network layer occasionally (layer 3).
• It enables multiple connections of many devices in the same network, as well as port and VLAN security settings administration.
• Switch is often used to connect numerous nodes in local area networks. A switch, like a bridge, uses the same forwarding or filtering logic on each port. When a network host or switch sends a message to another network host or switch, the switch receives the frames and decodes them to read the message's physical (MAC) address component. A switch divides a LAN into numerous collision zones, each with its own broadband connection, allowing the LAN's bandwidth to be significantly increased.
• Routers are network devices that operate at the OSI Layer 3 level of communication. Because layer-3 protocols have access to logical addresses( IP addresses), routers can send data across networks . Routers are sometimes known as Layer-3 switches.
• Router is a data packet forwarding network device. A router connects at least two networks, typically two LANs or WANs, or a LAN and its ISPs network and determines how to send each data packet based on its current network status. Its main goal is to use adaptive and non-adaptive routing to connect multiple types of networks at the same time. The router is connected to at least two networks.
• It controls traffic by routing data packets to the correct IP addresses and it determines the most efficient route for sending packets.

4. What is netstat utility?

This command is commonly used for incoming and outgoing connections, routing tables, port listening, and use statistics. The netstat command creates graphs that illustrate network and protocol statistics. In table format, you can see the status of TCP and UDP endpoints, as well as routing table and interface information. For example, while checking the status of a host's listening port or seeing whether remote hosts are connected to a local host on a given port, the netstat command is used.  The netstat utility can also be used to detect whether services on a host are associated with specific active ports.

5. What exactly is a Domain? What is the difference between a Workgroup and a Domain?

A domain is a type of computer network in which all user accounts, computers, printers, and other security principles are registered with a central database that is located on one or more domain controller clusters. A workgroup, on the other hand, is a peer-to-peer LAN that allows computers to share files and printers. Computers and other networking devices can all be part of a domain or workgroup. Each arrangement, however, has a different method of managing network resources.

The primary distinction between a domain and a workgroup is that in a domain, network managers utilise servers to govern all computers on the domain, but in a workgroup, no computer has control over another. Furthermore, devices in a domain can be connected to many local networks, whereas in a workgroup, all devices are part of the same LAN or subnet.

• Data Science

6. What do you know about Ping?

A Ping is a tool for determining whether or not an IP address is connected to another TCP/IP computer. It's a piece of computer network administration software that checks a host's reach on an Internet Protocol network. It's compatible with almost any operating system that has networking capabilities, as well as the majority of embedded network administration applications.

The PING utility validates reachability to the remote end's destination host using IP ICMP echo request and echoes reply messages. The reception of related echo Reply messages, as well as round-trip times, are displayed. The most used TCP/IP command for troubleshooting connectivity, reachability, and name resolution is ping. It contains two messages: the first is whether the data packet is capable of sending and receiving messages from the destination IP address, and the second is the process' RTT time (RTT means round trip time and is calculated in milliseconds).

7. What do you know about the protocol analyzer?

A Protocol analyzer is a sophisticated tool for locating network problems. It is the software that intercepts and records the flow of data packets between the source and the destination. For example, if the system is slow, it can check for latency difficulties and other networking issues, which will aid in the diagnosis of the main cause.

8. What do you understand about Safe Mode?

OS settings or other system issues might cause some program faults. Safe Mode is a troubleshooting environment available in both Windows and Mac operating systems. Safe Mode disables non-essential applications and processes, allowing you to isolate problems more easily. Whenever your system is in Safe Mode, run the troublesome software and try to reproduce the issue you were experiencing while it was in regular mode. If you don't experience the same issue in safe mode, it's likely that the problem is exacerbated by your operating system or another software rather than the application you're debugging.

9. Name three steps you'd take to troubleshoot a problem with an FTP server.

The three steps you'd take to troubleshoot a problem with an FTP server are:

• Ping can be used to test basic connectivity.  The "ping" command uses a "echo request," which is an ICMP component (Internet Control Message Protocol). When you ping a device, you're making an echo request, and if the device is active or online, you'll get an echo back.
• Use Nmap to see if the ports are open (20 and 21). The Nmap hosted security tool can assist you in determining the effectiveness of your firewall and security settings. Ports are numbered addresses for network communication on current operating systems. By default, different types of services use distinct ports. Because port configuration might pose a security risk, knowing which ports are open and which are blocked is crucial. 
• Check to see if the server's traffic is being restricted by a firewall.

10. A computer that is linked to switch port 23. The switch has figured out the PC's mac address. The port is now closed. Will the mac address be retained by the switch?

The mac-address will not be retained by the switch. A database is maintained in the switch where the mac address is stored. When the port is turned off, the mac address is removed from the switch's mac-address database.

11. To troubleshoot CPU performance issues, an administrator tries to run esxtop by enabling SSH and using putty, but no output is produced. What is the best way to solve this problem?

Press f and place an asterisk next to each field that should be displayed in ESXTOP to display output.

Esxtop displays status information for the physical server running an ESX Server. It displays CPU and memory use for each physical processor, as well as disc and network bandwidth for each network and disc device connected to the ESX Server system.

12. When debugging a VM's CPU performance difficulties, which counters will be used to indicate CPU contention?

The ESXTOP tool is used to evaluate the memory, CPU, and network utilisation of an ESXi host. It's an excellent tool for VMware admins to employ when dealing with performance concerns. To set up ESXTOP, you'll need the vSphere Client, as well as putty and SSH sessions. CPU performance is measured using the counters percent RDY, percent MLMTD, and percent CSTP.

13. Assume a virtual machine is turned off abruptly. To troubleshoot the issue, which VM log files should be considered?

If this occurs, an administrator should investigate the problem by looking at the vmware.log and hostd.log log files. Vmare.log log files keeps track of virtual machine and ESX host activity and the agent that manages and configures the ESXi host and its virtual machines is described in the hostd.log log files.

14. How would you prevent and troubleshoot internet browser crashes and freezes?

Several troubleshooting tips are recommended by Google, Mozilla, and Microsoft to assist you to figure out why your Internet browser fails.

• Mozilla, Google, and Microsoft distribute updates for their browsers Firefox, Chrome, and Internet Explorer regularly. These upgrades correct issues while also improving browser stability and security. Therefore, older versions should be updated from time to time.
• Add-ons make your online experience better, but incompatible add-ons may crash your browser. It's tough to know which of your add-ons is creating issues if you have a lot of them. All add-ons are momentarily disabled when you run your browser in safe mode. If your browser doesn't crash in safe mode, one of your add-ons is likely to blame. To discover the conflicting add-on, disable all one at a time.
• Malware might crash your browser at any time or when you access specific websites. Malware can reroute your Internet searches or perhaps even take full control of your browser. To scan for malware on your computer, Microsoft suggests using the Microsoft Security Scanner and antivirus.
• Reset the browser to its default state if all other troubleshooting methods have failed.

15. What is BIOS?

One of the most prevalent applications of Flash memory is for your computer's basic input/output system, sometimes known as the BIOS. When a computer is turned on, the BIOS allows it to do specific tasks right away. The BIOS' primary function is to control the early phases of a computer's starting process, guaranteeing that the operating system is loaded appropriately into memory. BIOS is vital to the functioning of most computers today, and understanding it can help you troubleshoot problems with your machine.

• The Power On Self Test is the first thing the BIOS does once you turn on your computer. The BIOS examines the computer's hardware at the POST to ensure that it can complete the startup procedure. When a POST is successfully finished, the system normally emits a beep. However, if the attempt fails, the system usually produces a sequence of beeps. The quantity, duration, and pattern of such sounds can help you figure out why the test failed.
• After the POST, the BIOS tries to load the operating system using a program called a bootstrap loader, which is made to look for any available operating systems and load them into memory if one is discovered. At this stage, the BIOS drivers are also loaded. These are programs that allow the computer to control hardware devices simply.
• In addition to computer security, the BIOS can play a role. The boot process can be password-protected in most BIOS software versions, which means you must provide a password before any BIOS action can take place. Because the BIOS performs nearly all of its duties during startup, the entire computer is effectively password-protected. Resetting a forgotten BIOS password, on the other hand, can be time-consuming and need access to some of the computer's highly sensitive components.
• The BIOS software is usually stored on a Read-Only Memory (ROM) or a flash memory chip connected to the motherboard of your computer. Because the BIOS software is the first to take control of the system when you switch it on, the position of the BIOS program on the chip is critical. Your computer's CPU would just not know where to find the BIOS if it wasn't constantly in the same position on the same chip, and the boot process would fail.

16. What should you do if you can't download a critical file because it's too large?

The issue of a file being too large for a USB drive can be solved quite easily by changing the file system of the detachable drive from FAT32 to a more current system, such as exFAT or NTFS.

Before you begin, examine the USB drive you're about to change for any vital files you own, and if it does, copy them to a separate location (such as the PC or a different removable drive). This is important since changing a drive's file system will wipe all of its contents. If you're unsure, go with exFAT: it has better support from non-Windows device manufacturers, so if you wish to use the USB drive with either a Mac or Linux computer, possibilities are they'll be able to open the contents without any additional adjusting. If you plan to use the drives with older Windows PCs, such as Windows XP, choose NFTS instead of exFAT because exFAT is a newer format that the older computer may not recognise.

Troubleshooting Interview Questions for Experienced

1. how would you fix the ‘no signal input’ error on your screen.

The most common fixes for the the ‘No Signal Input’ error on your screen are:

• Power and Cabling Issues: This may seem self-evident, but the solution could be as simple as double-checking all electrical connections and ensuring the input device is turned on. Make sure your video monitor cable or HDMI cable is securely attached to the PC or other input device as well as the display. If you're using a desktop tower computer, ensure it's turned on. Some PCs feature cooling fans that spin and create noise even when the computer is not turned on. Check that the power light is on and that the monitor and computer are both connected to a power supply. If you ever discover that your monitor isn't turning on properly, this is a superb method to employ. Examine the state of your power cord. This display problem can be caused by a faulty power cord or power strip. When working with a frayed or damaged power cord, use caution.
• Source of Input is Incorrect: Make sure the correct input source is selected if your monitor has multiple input channels. If you're using a video output or HDMI cable to connect to a PC, make sure the monitor input is set to the correct source, such as HDMI or Video. You can normally accomplish this by pushing the menu button until you find the input button on the monitor's main menu or control panel, then selecting the input button to cycle through the settings until you obtain the correct video signal.
• Setting the Monitor Resolution: If the monitor display resolutions are out of sync with the input signal, some external display monitors will display no image and an error message. The monitor may display a "no input signal" message if your PC video card or graphics card is set to a display resolution higher than the monitor's native display resolution. To find out what your monitor's maximum and native resolutions are, look at its specifications. If you're not sure and have a Windows PC, consider starting it in safe mode, which has a lower display resolution.
• Problems with Graphics Cards: If you're using a graphics card that can be swapped out, check sure it's firmly seated in its slot. Before removing an internal graphics card, make sure all cables are disconnected and the device is turned off. A display device may produce an error message due to a faulty video card or an incompatible video card driver. When a computer is turned on, never remove the cover.
• Experiment using a different cable or a computer: A damaged video cable is also likely to be the source of the monitor's lack of signal. If the problem persists, try connecting your monitor and PC with a fresh cable. If not, the problem is due to a problem with your video cable. If the problem persists, try connecting your monitor to a different computer. If your monitor still displays the no signal message, it's possible that the monitor is the source of the problem. In this scenario, you should seek further advice from the monitor's manufacturer.

2. An organisation's administrator is unable to telnet to a router that is located 10 hops away from the admin PC. What tool can be used to locate the point where the connection is lost? Explain more about the command.

The admin can use the traceroute command-line tool to inspect the location where packets are being dropped on the router.

Traceroute is a command-line tool used in real-time network troubleshooting to determine the path data packets traverse across the internet to their destination addresses. When you visit a website, the traffic must pass through multiple intermediaries before it reaches the website. The traffic passes through your local router, the routers of your Internet service provider, and onto larger networks, among other things.

Traceroute shows us the path that visitors take to get to the website. It also shows the length of time that each halt takes. If you're experiencing trouble accessing a website that appears to be operational, there could be a problem somewhere along the path between your computer and the website's servers. Traceroute would reveal the source of the issue.

In more technical terms, traceroute uses the ICMP protocol to deliver a series of packets (the same protocol used for the ping command.) The time-to-live (also known as TTL, or hop limit) of the first packet is 1, the second packet is 2, and so on. The TTL is reduced by one each time a packet is forwarded to a new router. The packet is deleted when it reaches 0 and the router delivers an error message. Traceroute ensures that each router in the path discards a packet and responds by forwarding packets in this manner.

3. An ADSL (Asymmetric Digital Subscriber Line) router connects a PC to the internet. The DNS server IP address is specified on the ADSL router. Is it necessary to configure the DNS server IP address on the computer to access the internet?

It is necessary to configure the DNS server IP address on the machine. Take the case of a person who wants to visit a website. When a user starts a browser and types the website's URL name, a DNS resolution is required, in which the URL name is submitted to a DNS server. The PC must start the DNS request, which necessitates the configuration of the DNS server IP address on the PC. The DNS request will fail if the PC does not recognise the DNS server IP address, and internet access will be lost.

4. How would you resolve DNS issues?

Following are some ways to resolve DNS issues:

• Check your cords and connections : If you're using wired connections, double-check that everything is correctly plugged in. If you're using a wireless network, ensure sure it's turned on and connected. Check to see if your router is turned on and working.
• Rule out ISP problems : Make sure you're not having problems with your Internet service provider by attempting to link with another device. If you can directly connect to your ISP without going through the router, do so.
• Reboot your router : Turn it back on after a minute and wait till the indicator lights cease blinking before attempting to connect.
• Scan for malware : In some situations, a virus could be preventing you from accessing the internet. In this instance, you may have more pressing concerns to address before addressing IP connectivity.
• Examine your TCP/IP settings : These options control how your computer interacts with others. You could have recently updated these settings and attempted to manually enter them. Find "Manage network connections" in your computer's networking or control panel. Locate and tap on both IPv6 and IPv4 "Properties" under "Local Area Connections," "Properties." Make sure "Obtain an IP address automatically" and "Obtain DNS servers address automatically" are both checked.
• Clean out your DNS cache : Your computer's DNS cache is where it saves networking information from previous visits and efforts to connect to online sites. The cache can get corrupted as a result of incorrect data. Type ipconfig /flushdns into the command prompt to flush, or clear, this cache. The DNS cache will now have to update the DNS information the next time you visit a website.
• Obtain a new domain name : Is your website address functional but taking you to an unfamiliar site? It's most possible that you neglected to renew the domain name. If necessary, update and reinstall the network adapter driver: When was the last time you updated your drivers? This may be causing problems, especially if you've upgraded your PC's hardware since purchasing it. You can fix DNS problems by manually searching for network device driver updates and updating them.
• Switch to Google's public DNS servers : Google's servers are usually more dependable and may be utilised without going via your ISP. You can change your DNS servers to Google's by altering the following properties in your Internet Protocol Version 4 (TCP/IPv4).

5. A customer requests your assistance in determining why a piece of software or utility fails to load or loads with an error. So, how would you help?

Below are some of the things that you would need to check to troubleshoot the software program:

• Check to see if the program's or utility's developer has any fixes or updates available. In some circumstances, the software program will need to be updated to work properly on the computer.
• When one executes the software or utility, one must ensure all other programs are closed. If the software runs successfully after all other programs have been closed, there may be conflicts with other programs.
• After the program is installed, ensure the computer is rebooted at least once. Some programs require a restart of the computer after installation to function properly.
• Check that the date on the computer is correct. Software may rely on the date in various circumstances, and if the date is wrongly specified, it can cause problems.
• If the aforementioned suggestions fail to solve your problems, reinstall the program or utility.
• Your operating system may be the source of your software problem in some circumstances. For this, basic operating system troubleshooting steps must be followed.

6. Can one recover data from a dead PC?

Method 1: The system isn't always completely dead. Sometimes, it simply won't start because of faulty or damaged system files, malware attacks, software problems, or missing DLLs. In such instances, the BIOS utility built into the system can be used to retrieve data. Follow the instructions below:

• Connect the dead system to a USB drive (made with the Windows Media Creation Tool).
• Turn on your computer, press the F12 boot key to access the boot menu, and select the USB installation media.
• You will then be taken to the Automatic Repair setup.
• It will say that the Automatic Repair failed to repair your computer, so select Advanced options.
• Click Troubleshoot->Advanced options-> Command Prompt.
• The window for the Command Prompt appears. Hit Enter after typing notepad.exe.
• Select File > Open from the File menu in Notepad.
• Select This PC from the drop-down menu, then go to the files and folders you want to recover.
• To access them, change the file type to the 'ALL FILES' from txt.
• Select the external disc from the Send to the menu by right-clicking on the chosen file.

If the data is stored on the c: drive, however, this procedure may fail. With the new Windows installation, the c: disc will be formatted permanently.

If your system won't start and you're worried about the loss of data, you can use the dead PC's hard disc as an external drive and follow the steps below:

• Remove the hard disc from the affected computer and attach it to a functional computer. To utilise it as a hard drive, use a hard drive connector such as a SATA to USB converter or an external Hard Drive Enclosure. Connect the hard drive to the PC using an appropriate connector if the PC supports PATA/IDE 3.0.
• Open Disk Management  by right-clicking (or long-pressing) the Start button and selecting disk management.
• Assign a drive letter to the hard disc if the system recognises it but shows it as RAW.

When your system fails to boot and you attempt to repair it, you run the risk of losing vital data. To avoid data loss, use reliable data recovery software to recover your important system files, photographs, videos, and documents. These programs provide a bootable recovery disc feature that enables you to recover data from crashed, corrupted, formatted or non-bootable computers.

7. Under what circumstances can you not convert a basic disc to a dynamic disc?

Dynamic discs are logical discs that can use several hard drives in the computer to provide disc redundancy, mirroring, and improved performance and reliability. Dynamic discs are a type of volume management that permits volumes on one or more physical discs to have noncontiguous extents.

It is not possible to transform every standard hard disc into a dynamic disc. Removable media, such as ZIP and Jaz discs, for example, cannot be transformed into dynamic discs. The explanation for this is straightforward. A dynamic disc is a storage device that can span many drives. The volume would be broken if it spanned a detachable disc and the disc was eliminated from the system.

If the basic disc is on a laptop computer, it cannot be turned into a dynamic disc. This can be due to a variety of factors. You ought not to be running Windows Server 2003 on a laptop in the first place. Second, the majority of laptops have only one hard drive. Dynamic discs would provide no benefit to a system with a single hard drive. Third, when a laptop has multiple hard drives, one of them is frequently located in a docking station. A dynamic disc volume that encompassed the device's internal hard drive, as well as the docking station's hard drive would indeed be damaged if you removed your laptop from the docking station.

Clustered servers are the third case in which a basic disc cannot be transformed into a dynamic disc. The final criteria about basic drives that cannot be transformed are that any hard disc with a sector size bigger than 512 bytes can't be converted (albeit this is unlikely). Cluster sizes larger than 512 bytes are possible, but not sectors.

8. Discuss the best Network Troubleshooting Practices.

It is also crucial to have some best practices in place to make troubleshooting as speedy and painless as possible. Following these best network troubleshooting practices as you strive to resolve network issues will help speed up the process and minimise superfluous or repeating efforts.

• Gather facts about network and network problems : To provide the greatest help to your end consumers, you must first determine what the issue is. Collect enough information from the people who are having network problems as well as the network itself to be able to duplicate or diagnose the problem. Take cautious not to confuse symptoms with the core cause, as what appears to be a problem may be a symptom of a greater problem.
• Logs can be customised : Make sure your event and security logs are set up to provide you with the information you need to troubleshoot and analyse the root cause. Each log should provide a clear explanation of the items or events being tracked, as well as the date and time, as well as information about the report's source (MAC or IP address).
• Examine security and access : Check that no access or security concerns have arisen by ensuring that all access permissions are as they should be and that no one has tampered with a sensitive section of the network they weren't meant to. Check that any firewalls, antivirus, and malware software are up to date and that no security concerns are interfering with your users' ability to operate.
• Adhere to an escalation protocol : There's nothing more irritating than going to the IT help desk and getting routed to someone else, who then directs you to someone else, who then refers you to someone else, and so on. Establish a clear escalation system that identifies who is responsible for certain concerns, as well as the last person in the chain who can be contacted for assistance. All of your end customers should know who to contact if they have a problem, so they don't waste time talking to five different people who can't help them.
• Using monitoring tools : Manual troubleshooting is possible, however, it can take a long time if you go through each step. It might be stressful to try to locate the problem, let alone remedy it when you have a slew of individuals banging on your office door or sending you frantic emails. It's best to employ monitoring tools in commercial and corporate circumstances to ensure you're obtaining all of the relevant network information and aren't missing anything crucial, not to mention avoiding exposing the firm to excessive danger.

SolarWinds® Network Performance Monitor (NPM) is my preferred monitoring software . It's a well-designed application with capabilities that help you debug network issues quickly and thoroughly. NetPath network path analysis, which shows your network topology and performance pathways, and PerfStack, which enables you to compare multiple performance measures against each other as well as historical data, are two more NPM capabilities. You can use these tools to see which performance issues are linked and troubleshoot the root cause more quickly.

9. What are upper layer faults and how do you rectify them?

If you still can't find a solution after examining physical connectivity, local connectivity, IP connectivity, and routing issues, the fault could be in the transport and application layer protocol.

A defect can occur for a variety of reasons:

• The data connection has been lost.
• Incoming and outgoing traffic is blocked by a packet filter or firewall.
• On the server, a specific service is unavailable.
• Between the client and the server host, there could be an authentication and access issue.
• Issues with software incompatibility or mismatches between the source and destination hosts.

10. How to troubleshoot IP related problems?

If we cannot reach the destination IP address and cannot identify a route to the next-hop at any point in the network using the TCP/IP protocol suite, we will utilise the PING and TRACEROUTE tools to diagnose the cause and location of the problem.

The following are some general steps to troubleshoot IP-related network issues:

• To begin, identify the pair of devices between the source and destination hosts that are experiencing connectivity issues.
• The failure could be due to a physical connectivity issue once you've located the devices using the tools. As a result, examine all of the physical connections along the path.
• If you work in a LAN network, there may be a problem with the LAN connectivity as well. As a result, double-check your LAN connections. The local port may be broken or unavailable, preventing the source from communicating with the destination IP.
• A router connectivity issue when travelling through numerous channels to reach the destination could be one of the causes of the error. As a result, verify that the router is appropriately defined at each intermediate hop.
• Examine the configuration options.

11. How to troubleshoot local connectivity issues?

If you discover that there is a problem with LAN connectivity on a huge level, you should take the following actions to identify the root cause and resolve it:

• Ping the destination IP if the destination and source have the same subnet mask.
• Otherwise, ping the router's gateway IP address if the destination is on a different subnet mask.
• If both pings fail, first verify the configuration settings to see if the subnet mask and route to be taken to reach the target are properly defined in the routing table.
• Check if your source host can ping another hop in the LAN network other than the destination host or route to that once you've completed the configuration section and verified everything to be in order.
• There could be a variety of reasons why you are unable to ping another device. It could also be a setup problem, a physical connectivity problem, or a problem with repetitious IP address entry.

12. What does the term "disc error" mean, and how would you respond if you received this message?

When the computer BIOS cannot detect a bootable operating system on any of the storage devices included in the notebook computer's boot path, the Non-System Disk Error or Disk Error message appears.

Here are a few approaches that may be useful, and any of them may be the answer to your problem.

Method 1: Examine all non-bootable storage media.

First and foremost, make a list of all non-bootable storage devices connected to the computer and remove or detach them. When you connect many devices to a computer, the system may have trouble determining which device has the OS loaded, which can result in an error like this. As a result, disconnect all non-bootable external devices.

Method 2: Check the IDE ( Integrated Drive Electronics ) or SATA ( Serial Advanced Technology Attachment )cable on the HDD.

If your hard disk's IDE or SATA cable is damaged or improperly attached, the system may be unable to read the disc, resulting in the "non-system disc error." If the cable is damaged or malfunctioning, simply reconnect it properly or purchase a new one.

If the HDD cable is in good shape and securely attached, but the error remains, it's possible that the HDD on which Windows was installed is not set as the primary disc in BIOS.

Method 3: If necessary, change the boot order.

Access the BIOS/UEFI environment on your PC and make sure the hard disc drive you're trying to boot from is in the correct boot order settings, which should be at the very top of the boot order list. To alter the boot order, follow these steps:

• While the computer is restarting, press the key required to enter the BIOS or UEFI setup screen (usually Esc, F2, F8, F10).
• Select the Boot tab in BIOS with the arrow keys on the keyboard and give the system drive the boot priority, which should be set at the top.
• The mouse pointer can be used to specify the boot sequence in UEFI.
• The BIOS/UEFI setup utility should be saved and exited. The computer will reboot with the new settings in place.

Method 4: Reinstall the hard drive.

Another option for resolving this issue is to remove and reinstall the hard disc.

• Remove the power cable/charger from the PC and turn it off.
• Then the battery should be removed (for laptops).
• Disconnect the hard drive from the computer.
• After blowing out the dust, clean the hard disc using a dry rag.
• Reconnect it to your computer.
• Return the battery to its original position.
• Connect the charger or power cable.
• Restart the computer.

Method 5: Access hard drive and recover data from the hard disk without OS.

Except for external influences, you must accept the fact that something went wrong with the hard disc drive's boot files, which may have gotten damaged or corrupted, and that fixing the HDD's boot sector, master boot record (), and boot configuration data (BCD) must take effect.

• Make a bootable Disk.
• Proceed by booting from the bootable USB.
• Recover data from a non-booting hard drive.

13. Explain differential backup vs incremental backup.

The fundamental distinction between incremental and differential backups is that incremental backups save space and time by simply saving modified data. Incremental backups, on the other hand, are not as effective as differential backups. Let's discuss Full Backups before diving into the distinctions between Incremental and Differential backups. A full backup is the launching point in both incremental and differential backup schemes in their most basic form. Of course, a complete backup backs up all the information on a partition or disc by copying all data-containing disc sectors to the backup image file.

An incremental backup is a copy of any data that has changed since the last backup. As a result, if you make a full backup of your system on Sunday, an incremental backup on Monday will only transfer and save data that has changed or been added since Sunday. On Tuesday, an incremental backup will only deal with data that has changed since Monday's incremental backup, and so on. The differential backup, unlike an incremental backup, only backs up data that has changed since the last full backup.

The difference between incremental backup and differential backup is given in the table below:

Daily, a differential backup approach backs up files that have changed since the previous full backup. Because less data is stored up, they are much faster than complete backups. In contrast to differential backups, incremental backups copy files that have changed after the last backup of whatever type, which can be a complete or incremental backup. The fewer data that needs to be backed up when incremental backups are conducted, the shorter the time between backups.

One of the advantages of differential backup over incremental backup is that you just need the most recent full backup and differential backup to recover data, which speeds up the process. However, until the next full backup, the amount of space needed by backed up data will increase with each differential backup.

Among the three strategies: full, differential, and incremental, incremental is the one that saves the most space. Even though the incremental backups offer more versatility and granularity (duration between backups), they have a tradition of taking longer to restore because they should be built from the most recent full backup and all successive incremental backups.

14. Why is it important to test your computer’s RAM? How can you do it?

The working memory of your computer is its random access memory (RAM). The operating system and programs on your computer are constantly writing and retrieving data from RAM. When you open a web page such as this one, for example, your web browser saves it in RAM as you read it. When you start a PC game, it loads data from a slower storage system (such as a hard disc or solid-state drive) into considerably faster RAM.

If your computer's RAM is defective, you may experience issues. When your computer goes to read the RAM, it will consider various data than it saved to RAM. Software crashes, system freezing, blue screens of death (BSODs), file corruption, and other issues can result as a result of this. These programs work by writing data to every sector of your computer's RAM and then recovering it back in a sequential manner. If the utility returns a different result, it means your RAM is bad.

The finest RAM testing software necessitates booting into a separate bootable system. This gets Windows (or some other operating system) out of the way and gives the tool complete access to your RAM at a low level. You can run tools from within Windows, such as HCI Design's MemTest, but they aren't as trustworthy.

• Launch the Windows Memory Diagnostics program. A RAM testing tool is included with Windows. It comes preinstalled on Windows 10, Windows 11, Windows 7, and all other recent Windows versions.

• You can install and use MemTest86 if you need a more capable testing tool. It runs a larger range of tests and may uncover issues that the Windows test would miss. If you want to try something else, MemTest86+ is a free and open-source program. Both of these programs are self-contained and bootable. You can copy a USB image from MemTest86 to a USB disc. To make a bootable USB drive, simply run the EXE file provided with the download as well as provide a spare USB drive. Restart your computer once you've made bootable media and instruct it to boot from the USB device where you copied the memory test tool.

15. A consumer claims that their Windows restarts at random intervals. What are your thoughts on this, and how would you solve the problem?

If your Windows machine restarts without warning, consider the troubleshooting methods below for assistance in addressing the issue.

Software issues : Microsoft intended Windows to automatically reboot when issues, such as a blue screen of death, occur since the release of Windows XP. Although this feature is useful for random failures, it makes troubleshooting and repair more complex. The procedures to disable and enable this function in Windows XP, Vista, 7, 8, and 10 are listed below.

• Right-click My Computer on the desktop. Open File Explorer in Windows 8 or 10 and right-click This PC in the left navigation pane.
• In the pop-up menu, choose the Properties option.
• Select the Advanced tab or the Advanced system settings link in the System Properties box.
• Click on The settings option under Startup and Recovery on the Advanced tab.
• Disable the Automatically restart check box in the Startup and Recovery window.
• Click the OK button.

Hardware issues : If you've previously attempted to introduce a new hardware device, make sure it's not the source of your problems. By looking for problems in Device Manager, you can make sure you're not having any hardware conflicts. If you've just installed new hardware drivers, you might want to go back to an older version. If the unexpected reboots persist despite updating drivers and removing any newly attached hardware, the computer memory is bad. Finally, improperly installed hardware devices in the computer can result in random reboots. Ensure that all cables and expansion cards are correctly connected to the computer.

Computer viruses: These viruses usually cause the computer to reset every 5, 10, 15, or 30 minutes after it has booted. If you suspect your computer is infected, make sure you have an antivirus program installed and that your virus scanner definitions are updated.

Overheating: Most computers today are intended to shut down or reboot automatically if the processor, video card, or other components become too hot. Examine the rear of the computer to see if the fan on the power supply is operating. A temperature gun can be used to determine how hot the computer's hardware devices or integrated circuits are.

Issues with the Operating System: If your computer continues to reboot after completing the steps above, you're most likely dealing with a problem with the Microsoft Windows operating system. When the computer starts to boot up, restart it and enter BIOS setup. Allow the machine to sit idle for several minutes after you've loaded the BIOS setup.

If the system doesn't reboot after resting in BIOS and you've exhausted all of the above options, try enabling a restore point in Windows from before the problem began. If enabling a previous restore point fails, or if no restore points are available, you will most probably have to reinstall Microsoft Windows.

Question 1 of 25

Tell me about the most challenging problem you have encountered in your professional career.

How to Answer

Answer example.

Everyone has had their share of challenges in their career. The interviewer knows that you are not perfect; however, they need to know that you can professionally overcome work-related roadblocks. Maybe you had a significant project that almost went sideways. Perhaps you had a conflict in the workplace that you could have handled more professionally. Explain your approach to resolving the issue and be sure to highlight the steps you took to reach that resolution.

"The most challenging problem I have encountered in my professional career was with my most recent employer. I had an incredibly important project that made up the majority of my annual budget. The client was challenging to work with as he was rarely available for comment, due to extensive international travel. I needed this deal to work out so, for the 6-month span of the project, I made my work hours reflect his time zone. This shift allowed us to communicate via Skype on a daily basis which meant a fair share of late night and early morning calls for me! It was a sacrifice, and I would do it again. I understand that sacrifices need to happen to gain successful outcomes."

"The most challenging problem that I encountered in my career was when my former company experienced a major merger. It was a lot to adjust to but, after some time, I was able to get a good pace again."

"The most significant challenge I have faced as a manager would be the labor dispute and lockout that our company went through in 2016. Many of our permanent employees are union based. We could not come to a new collective agreement, and so I ended up having to utilize a lot of temporary staffing options during that time. It was a lot of re-training, and strain on the company culture overall."

"The biggest challenge that I face as a marketer, and it's an ongoing challenge, is to manage my expectations on projects. I lean on the side of perfectionism and often put more pressure on myself than even a client would. The positive side of this; however, is that I always deliver an immaculate product."

"I'd say the most challenging problem I have encountered was when my manager suddenly resigned. I was then in charge of the department. Now, I was mostly ready for the responsibility, as the assistant manager in the department. However, I had never completed inventory reconciliation, and on the first day, this was my first task. I was asked to give projections so that our buyer could stock us for next season. I had no idea what to do, so I researched until I came up with the answer. Also, other managers in other departments helped to guide me. Ultimately the work paid off because our next season projections were perfect. Since then, I've learned more effective ways to do our inventory management and projections, but I don't think I've ever learned anything as quickly as I did that week."

"The most challenging problem I've encountered is the misstep of taking my current role. The initial pitch to me on company growth and my duties is not my reality. This factor has been a challenge to my career growth. I know that even if it was a misstep, there are lessons to be learned, and I approach each day with interest and a positive attitude to try to learn those lessons and grow professionally."

"The most significant challenge I've faced is nearly having my department eliminated due to budgetary cuts. I was lucky to have an active parent community rally behind me and the department which saved the program, in the end. The other challenge that comes to mind was getting back into the swing of teaching after taking a few years off to be home with my children. There was a learning curve on getting up to speed with curriculum and the lesson planning, but my love for teaching made it all that much easier!"

1. Tell me about the most challenging problem you have encountered in your professional career.

2. in your opinion, what makes you a great problem solver.

Employers want to know that you have a methodical approach to problem-solving. Consider the skills and qualities that help you successfully face problems. Perhaps you have a keen eye for detail. Maybe you can see opportunity when others can only focus on the issue. Share your strengths as a problem solver, and your ability to come up with innovative solutions. Strong problem solvers are: - Systematic thinkers - Open minded - Okay with being wrong sometimes - Always researching and exploring - Able to identify the core problem - Able to reverse engineer a challenge to avoid future issues - Able to come up with multiple avenues that work well for all stakeholders - Are do-ers and not worriers

"I am a great problem solver because I can compartmentalize all aspects of a problem before studying it. I also like to bring more experienced team members in to add to the solution. I will never try to be a hero and solve a complicated problem without tapping into the resources around me."

"What makes me a great problem solver is that I have a keen ability to research, read, and explore so that my recommendations are based on fact and study rather than guesses."

"I have been told that I am an excellent problem solver and I believe this is because I have a bit of an engineering mind. I can take the issue, work backward to solve it, and then use that resolution as a basis for avoiding future issues to come up. I am also a big-picture thinker which allows me to come up with various resolutions per problem."

"I am a great problem solver because I do not allow stress to cloud my judgment and mute my creativity. I am a keen observer with a great memory which allows me to recall unique solutions or ideas."

"I am a great problem solver because I draw from the experience of others, whether solicited advice or through my prior observations and then I improve upon that, where possible. My memory and years in the industry have exposed me to many types of situations and problems, so I feel I have a vast amount of experience to draw from, allowing me to be creative and effective in the way I approach any challenge. Not to mention, I'm not afraid to ask for help or advice along the way. I know that I don't know everything, so I like to ask for input when I feel I am not fully equipped to do the job alone. There is no shame in that."

"I believe I am a great problem solver because I am sure to gather as many facts as possible, I look at the problem and its potential solutions from multiple angles, and I am not afraid to make a creative decision, that might seem off the beaten path."

"I consider myself a great problem solver and believe my skills are in my emotional intelligence. I can be really in tune with the tone of the group, who is feeling what, and how they are each best reached. This skill applies to both adults and children, so it is beneficial both inside of the classroom and out! By being aware of what is at the heart of the matter and how each person needs his or her needs met, I'm able to accomplish a lot while avoiding many common landmines."

3. Tell me about a time when you discovered a problem and went beyond regular expectations to fix it.

Your innovative approach may be exciting and unconventional, but can you implement it realistically? Ideas are one thing, but putting them into practice and providing measurable results is where you can add genuine value. Think of a time you worked long hours and made sacrifices to overcome a challenging problem. Demonstrate your impact and the significance of your solution.

"During our busy tax season I noticed that one of our primary spreadsheets was not formulated properly. I am not an expert with Excel; however, with everyone being in peak stress mode - I decided it was something I could learn on my own. I watched a few online tutorials and ended up resolving the issue without the need to involve the rest of the team."

"When I worked as an admin assistant at my last job, I was in charge of purchasing office and kitchen supplies. I noticed we had been spending quite a bit of money on paper and plastic-ware. I compared the cost of disposables to the cost of buying permanent dishes and utensils for the kitchen. It turned out we were able to save the company hundreds of dollars each year by simply investing in dishes and silverware!"

"I had a staff member who was stealing supplies. Rumors were going around that she was dishonest; however, there was no evidence. I carefully waited and, after two days, the rumored infractions were caught on camera. At that point, I was able to terminate her employment. I went beyond regular expectations by gaining evidence before terminating her. I knew this would prevent a human resources issue down the road, and it also saved my company from having to pay this employee any severance pay."

"Our agency performed a major client launch last month that tested well. Upon implementing, I noticed that their new website was not functioning correctly. I wanted our client to be happy with our services, so I worked late into the night with our IT team to troubleshoot the site and ensure that by morning, there were no more kinks to work out. In the end, our client was thrilled with my dedication, and they ended up writing an amazing review online and even mentioned me in the review!"

"I managed a coat department previously and, depending on the season; these coats were very high ticket items. I had two salespeople who were consistently battling for the sale. It was unbecoming, to say the least, and impacted the department's morale. To incentivize everyone to go for the sale, I made a sales contest on non-coat merchandise. The more items they upsold, despite being a smaller sale, the more tickets they received towards various other compensation incentives like gift cards or extra time for breaks. The other sales reps felt reinvigorated, and it pushed my two coat-fighters to step outside of their perceived territory."

"In my first role, there was a regular lane of shipments that was difficult to cover. The issue didn't cause us to fall short as far as the customer was concerned. However, we were in danger of potentially having the customer poached due to waiting times. After several late nights attempting to come through for a key customer, I got tired of running in a hamster wheel. I decided to find some carriers that could assist. Long story short, after staying late many days and making some creative calls to find a backhaul, I was able to secure a new carrier, at a great rate, and keep the customer happy."

"When I was reworking lesson plans, I noticed that there was a gap between the programs and some policy. So, rather than hand them back to the team to fix, I took it upon myself to write the remaining lessons and tweak the existing ones to make them cohesive. It took about seven days of working on my own time, but it was worth it when I saw the lessons in action during the school year."

4. Tell me about a time where you had to analyze a set of data and then make a recommendation.

Talk about your attention to detail and sharp focus when it comes to data and statistics. You may not consider yourself a highly analytical person. However, this is a skill that you have indeed exercised in the past.

"I worked for a financial firm last year and had a client who was looking for investment recommendations. I gathered data on the stocks they were interested in, sorting through 12-month trends and further historical data to determine the most promising returns. The client was happy with my findings, and my manager was quite impressed with the research that I conducted."

"My boss recently asked me to make a case for Oracle on Demand versus SAP Business ByDesign. Our business was growing so fast, and we needed a new CRM fast. I called both companies who took me through a webinar and a couple of online tutorials. I then gathered the data and made an informative PowerPoint presentation. My boss was very impressed with how thorough I was, and I was happy to learn something new!"

"Each time I onboard a new client, I analyze a set of data before I make any recommendations on their strategy. This data includes their current analytics, primary sales sources, key customers, and more. I have a formula that I follow for the most part to help me assess and then give the best strategic recommendations that I can."

"My current employer wanted to know the exact impact our social media campaigns were making. I gathered our Facebook analytics for him and created a short PowerPoint presentation from the data. My recommendation was to increase our keywords in the geographical areas where our ads received the highest click-through rates. My research and recommendations certainly helped as our Facebook reach grew exponentially."

"As department manager, I'm responsible for forecasting what our sales will be for the upcoming season so that our buyer can accurately purchase the proper inventory. I have to look at our current inventory, last year's trends, YOY growth, and what the industry is doing as a whole, especially with the impact of online retailers. I then make a recommendation and forecast that will either set us up for success or not. If I under or over forecast, we end up with not enough inventory or too much to sell through and the cost is either opportunity in missed sales, or having to discount unnecessary items. To date, I've been nearly exact in my predictions."

"When doing annual reviews with my clients, I would analyze the past year's shipments, trends, and overall data. I would then make recommendations for improved efficiencies, rates, and better service contracts in the upcoming year. I would make not only carrier recommendations based on service level and pricing, but also made suggestions on new routes or ways in which we could be creative, like consolidating the shipments in our warehouses, to save cost when possible. I managed two of the most significant accounts in the office, so my recommendations were fundamental to our bottom line, and I'm happy to report that they were consistently adopted, resulting in more business."

"I am responsible for analyzing the results of our unit tests given across the department quarterly. I had not only to compile the results and make recommendations as to what units to keep and what to remove for the following year but also diagnose what ineffective and how we could remedy that. This task is a critical one as it shapes the future of the department and our efficacy as teachers."

5. When a problem requires a quick solution, how do you respond?

When it comes to complex problem solving, decisions are not always readily reached. It takes practice, experience, and confidence to learn what sorts of decisions yield the best results. Walk the interviewer through your process when it comes to making quick decisions. Do you rely on past experiences? Perhaps you go with a gut feeling. Maybe you have read case studies that you lean on in these instances. Problems that require you to act quickly can be emergency situations such as knowing where the fire extinguisher is and grabbing it fast enough to put out a small grease fire in the company kitchen. Other quick decisions could be if you are asked to take on a new responsibility and are only given five minutes to decide if it's something you are prepared to take on. Going with your gut is a skill, and the more you learn to trust your intuition, the easier it becomes to make these types of decisions. Demonstrate that you are confident and able to react swiftly when the need arises.

"Our Controller recently came down with pneumonia on a week where we had a major client presentation to give. He sent me what he had prepared, and I had to fill in the blanks. As an Analyst it was a bit out of my wheelhouse, being in a client facing role, but I adapted quickly, and reminded myself that my team needed me."

"When an urgent problem arises at work, I always try to respond in a calm and assuring manner. I am a natural leader which means that my team often looks to me for answers. One instance of my fast-thinking was just last week when we had an administrative employee no-show on a significant day for us. I called a temp agency, and they had the position filled in just one hour."

"In logistics, there are often split-second decisions that can either get the freight to a customer on time or cause a shut-down of a production line. Sometimes, these decisions have to be made after hours. On more than one occasion, I've received a phone call from our central dispatch asking me how to handle a late driver. I have to remember the details of the particular shipper or receiver, my customer, and the actual load in question but also get creative with how they can make sure to meet customer expectations. Due to the urgent nature of the business, as well as the drivers, it has to be a very quick decision to be successfully resolved. Luckily, due to following my gut, I've been able to make very fast, split-second decisions in the best interest of the branch and customer."

"As a Marketing Director, I need to make a multitude of decisions, on the fly, for varying projects. I rely partially on the instinct that I have built as an expert in the marketing industry and part in past experiences that may be similar. I am sure always to exude an air of control when making decisions."

"I thrive under pressure and always have, so when I'm given a time-sensitive situation to address, I light up and get down to business. I am more impactful and even more creative when I have little time to do much besides jump in and take charge. This ability to make fast decisions is especially helpful in my role as manager when there is an inventory, personnel, or customer issue."

"Just like with negotiations, I react swiftly in emergency situations. Perhaps my skills come from my years as a parent, having to think fast and put out fires! If a quick solution is required, I will do a fast overview of the facts and make a decision based on risk factors considering the potential financial loss."

"I am certainly a take charge and tackle a project kind of gal - as a teacher and a mom, too! I feel I have a powerful and accurate intuitive sense and I follow it instinctively. It's very rarely steered me wrong."

6. When it comes to problem solving, are you a strong collaborator?

Show off your teamwork skills by giving an example of when you successfully collaborated with your coworkers. Be sure to demonstrate how you communicated your thoughts or opinions. Highlight how your contributions, or ability to ask for help, made a difference. Explain how you are a team player who enjoys working alongside others.

"Last month, I recruited a couple of coworkers to help me solve a problem for a client. We were looking at their financials, but something didn't add up, and I didn't have the analysis background that these two co-workers had. Together we molded our areas of expertise and created a bulletproof financial plan for our client. I enjoyed the collaboration and would do it again in a heartbeat."

"I am most certainly a strong collaborator! Being an executive assistant, I am often in need of strong collaboration to complete a project for the VP who I support. I love learning new things from my coworkers and those who I report to."

"I love having impromptu brainstorm sessions with my team. It keeps everyone on their toes! When an issue comes to light, I will approach the problem with the entire team and open the floor, at the end of the meeting, for suggestions."

"In marketing, it is imperative to collaborate and gain different sides of the story, and new opinions. I try to seek out my team's opinions on projects all the time. I find everyone has something to contribute and can help me see a problem or strategy in a way that I may not have ever considered."

"I would consider myself an active collaborator and believe that two heads are almost always better than one. Three is the best, in my opinion. This way the team is odd-numbered, so if there's a dispute you can take a vote on it! Multiple viewpoints are almost always a great idea."

"I am a strong collaborator. I am always willing to listen to others' opinions, hear their perspective, and work together to build a solution that will fit for everyone. I am always looking to draw from others' experience and expertise to bring about the best solution for the client and the branch as a whole. When drafting a pitch for a client, I am always sure to bring on a manager or carrier sales rep so that I will have multiple perspectives to help bring us to the best collaborative solution."

"I believe I'm a skilled collaborator and am confident that my coworkers would agree. I come to our bi-weekly department meetings full of ideas and with an open spirit, ready to collaborate with the rest of the team. We always have engaging discussions that result in great takeaways for the teachers as well as our students."

7. When you cannot seem to find the right solution to a problem, how do you deal?

Sometimes, problems just seem too impossible to solve, at first glance. Your creative problem-solving skills may be at a stand-still from time to time, and the interviewer wants to know how you deal with that. Taking a brief break and stepping away from the problem can help you to see things from a different perspective. When you are in a rut, you can waste time plugging away at something, resulting in a decline in productivity. Discuss with the interviewer how you handle being in a rut like this.

"If I am stuck on a particular problem, I will take a break from trying to figure out what's wrong and ask a coworker for advice. Getting another person's perspective when you start to feel like you're hitting a wall can help one to see a problem with a fresh set of eyes. As humans, sometimes we overthink! The biggest hurdle can be asking for help, and I am not above asking for help when I'm stuck."

"If time allows - I will sleep on it! When faced with tough decisions where an answer does not come to me easily, I will take a moment to feel the issue out. When necessary I will also bring in the opinion of the administrators in a different department."

"If I cannot come to a solution that feels right I will check in with other leaders whom I work with and, depending on the situation, my business mentor. It's important to check in with those that I admire as they have unique ideas and some have more industry tenure as well."

"As a marketer, I am hired to find the solution for others. As you can imagine, when that solution seems elusive, it is incredibly challenging for me to accept. For this reason, I love brainstorm sessions with my team. I will also look to the outside in the form of resources online such as blogs and forums by other marketing professionals."

"It can be frustrating when a solution does not come fluidly. However, sometimes trying a solution and seeing it fail, will lead you to a lightbulb moment. I am an active person, so I like to walk and talk things out. Usually, as I do that, I don't filter my ideas. This way, something slips out that I would have edited out as "ridiculous" if I were writing down a list. I have found that this free-flowing problem-solving session often leads to the most creative and impactful solutions which I would have nixed from the get-go had another not failed."

"If I'm stuck on a problem, I try to take some time away from the issue, ideally by taking a step away from the screen and get my blood flowing. Walking away seems to help me get reinvigorated and more creative. I also find it valuable to talk it out with someone, even if that person is not a stakeholder in the situation."

"If I am stuck in a rut or can't seem to figure out the best approach, I am fortunate enough that I have so many other tasks and classes that I can focus on. Usually, if I clear my mind and fill it with something else, a great idea hits me when I least expect it. If I am stuck on a problem and cannot take the time to step away, I usually rely on my students to help me shake it off!"

8. When faced with a problem, how do you decide on the best solution?

There may be more than one solution to a problem, and the interviewer would like to know how you make a final choice when you're in a situation like that. Effectively comparing and contrasting, or weighing the pros and cons, is essential when choosing the best way to solve a problem. The interviewer wants to see that you are capable when it comes to calculating risk vs. reward. Think about a time when you have compared the risk and reward to a potential solution.

"If I have a problem with multiple solutions, I always go back to the classic pros vs. cons method. I fully understand that although no solution is perfect, and some solutions offer lesser sacrifice while others pose potential loss. I have been trained to take the solution that is 'closest to the money' which means that if I am stuck between a rock and a hard place, I will choose the solution that is most beneficial to the company's bottom line."

"When it comes to problem-solving, I will always weigh the pros and cons before making a decision. I will also bounce my thoughts off of some co-workers if I still feel conflicted after that."

"My decisions are always based on three factors. One, what is best for the company. Two, what is best for our clients. Three, what will boost employee morale. Now, not all decisions will be popular with all three groups, and I do keep that in mind. In those instances, it is my job to watch our bottom line but ensure customer satisfaction at all times."

"Rock, paper, scissors! Kidding - of course! Our team will collaborate on tough decisions, and we often vote. Majority wins in our office for many creative decisions."

"When I face a problem, I am sure to draw on previous experiences both as a customer and an employee in retail. I then use these experiences to make the most informed decision that I can about the problem at hand. Generally speaking, if I've already seen or experienced a very comparable situation, I can be impactful and exact in my approach by drawing from those experiences."

"As I consider a problem and its solutions, I make a note of what my gut tells me what to do. Then I take a step back and reflect on times that I have faced the situation before. I recall the actions that I took, the outcome, and then pivot as necessary. I trust my instinct because I am heavily knowledgeable in this industry, but I believe in relying on fact as well."

"I am typically a follow-my-gut type of person, so I follow my instinct when possible. I make a note of what my initial inclination was and then I make sure to compare and contrast solutions. Once I have identified the best solution, I check in to see if it feels right. More often than not, my initial instinct is correct. Of course, I am sure to be analytical as I weigh out each decision."

9. How do you prioritize multiple projects when they all seem equally important?

Prioritizing is a skill that requires practice. There are many approaches you can take. Here are some suggestions: 1) Make a list. By thinking through and writing down each item that needs completion, you can see it on paper. 2) Mark what is urgent or essential. Take into account deadlines and meetings. 3) Order each task based on effort and estimated value. 4) Consider due dates and how long it will take to do each item. When answering this question, show the interviewer that you have a system in place that helps you to think through what needs to happen, and when. The better you can prioritize, the more productive you will be, making you an asset to their company!

"I aim to be as effective and efficient as possible and make sure I can use all minutes of a day for a project. I have a few things going at once most of the time. I am the lead on some, the delegator on others, and the reviewer on another, for instance. This way, by splitting up the work to the appropriate parties, both my team and I can be the most efficient with our time."

"I often have multiple projects due at a time, since I am the assistant to three different executives. I ask my executives to rank their need from 1-5 in the level of urgency, including its due date. I start my work on that list. If there is more than one urgent need, I will work overtime, or through my lunch, to ensure that I deliver everything on time."

"I had to utilize creative problem solving last month when we found ourselves short-staffed and unable to hire new employees due to budget cuts. I changed our schedule to include some split shifts and received approval for a small amount of overtime spending. The problem is solved, at least temporarily, until our company comes out of our spending freeze."

"In my current department, we are very systematic in our customer delivery promises; however, that is not to say that doubling up on client deliveries does not happen. When situations occur where I have to prioritize, I will do so by the size of the client and budget. It may seem unfair at times; however, our largest clients with the most significant spend always rule out."

"I prioritize based on urgency and time required for the project. I have a list of what needs to be done, by when, and how long I estimate that it will take to accomplish. I am great under pressure, but try to make sure that I don't get myself or my team into a sticky situation by not allotting enough time for any particular project."

"I love to keep running lists of everything that I need to do, big or small. Mostly because I love crossing things off of the to-do list, but also because it helps me keep track of everything. Lately, I've started utilizing a free project management software that I use to make those lists, categorize the tasks, and mark them by the level of urgency. I take care of the most time-sensitive issues first and then move along to the equally important, but perhaps less time-sensitive to-dos. I also estimate how long each task will take, so if I have a few minutes in between projects, I can tackle the quick to dos and use that time effectively, rather than use it to figure out 'what's next.'"

"I follow the tried and true practice of making lists and assigning each item a priority and tackling the list that way. I love to check things off my list, as it gives me a feeling of accomplishment. Also, I am a believer in following my intuition. If I feel that something lower on the to-do list needs to be bumped up in priority, I will tackle that right away. As a teacher, there are always a lot of simultaneous to do items, so in addition to prioritizing, I have to be good at multitasking; something I find I do quite well as both a teacher and a mom."

10. Tell me about a recurring problem that you run into in your current position, and how you handle it.

The interviewer wants to see that, despite this recurring problem, you take action to find a resolution. They want to make sure they aren't hiring a chronic complainer who is easily defeated! Be careful to avoid complaining about your current (or most recent) position. A recurring problem could be a glitchy software system, an employee who is regularly late, or even an unpredictable work schedule. Remain optimistic in your reply!

"A recurring problem that I have in my current position is the fact that our client management software is not user-friendly. Any entry that I need to make is incredibly time-consuming which poses a real problem when a deadline is present, or when we have clients waiting for an answer. I have found that the best workaround for this is not to allow my paperwork to build up. The more proactive I am, the better I can keep ahead of schedule."

"A problem that I am currently running into is a lack of office supplies. My boss has been running very lean, financially speaking, since our industry took a downturn. I have to time my ordering with client invoices at this point. This situation has certainly helped me to become more aware of spending and budgets, that's for sure!"

"The greatest issue in my current position is that we have so much employee turnover. It started to feel like I was constantly training new staff. I came up with an employee referral bonus program which greatly helped. For every successful referral, our employees get $400 plus another $400 after their referral stays for three months. I believe this has been successful because the quality of our employees has greatly increased."

"In my current office, we have more clients than we can handle - which is a great thing! However, it's been tough to find the best marketers to join our team because we are a small organization. This hiring situation has meant a lot of overtime hours, which I am certainly happy to do for the most part. I do look forward to working with a bigger team, like yours."

"Unfortunately, a recurring issue in my current company is employee tenure. It's just really part of the industry as we need some holiday and seasonal associates and they typically don't want to stay on, or we don't have the budget to keep them on. This turnover means we are continually becoming a new team and learning how to work with our new coworkers. Scheduling often has a learning curve with a new team, too, because you have to take into account the availability of all parties, and who works well together. That said, it's something I'm used to. I make it a bit of a personal challenge or game for myself. How quickly I can learn their available days, how fast I can learn who works best together."

"A recurring issue at my current job is lack of reliable inventory that my clients are requesting, which can be incredibly frustrating. I am working hard to land a client, get them to buy into our program, both literally and figuratively, and then we fall short of expectations when our inventory doesn't meet their standards. That said, I continue to go out, land new clients, and try to source the proper inventory for them."

"A recurring issue revolves around my lack of a classroom and the friction that can arise at times because of it. Without the flexibility of my own classroom, I sometimes find myself in an awkward situation since I have to abide by the other teacher's rules, which sometimes conflict with mine. I do my best to follow the teachers' class rules, and make sure that we have a good understanding."

11. Tell me about a time when you failed to solve a problem. How did you overcome the failure?

'Success is bouncing from failure to failure without losing momentum,' or so they say. Your resilience shines through when you can learn from your mistakes and keep going. Give an example that shows you can accept fault and learn from challenging experiences.

"I failed to meet an important deadline in my first job out of college because I didn't know how to prioritize properly. I kept letting other menial tasks get in the way rather than focusing on finishing the project. I learned how to manage my time wisely by setting reasonable goals and reminders on my calendar. This technique helped me to manage my time more effectively."

"Last month we were having issues with our GoToMeeting application, and it was right before a major client meeting. I was on a call with the service provider, trying to troubleshoot and unfortunately, did not deliver a fix on time. After the initial frustration, I decided to talk to my boss about having backups in place. Now, we have Skype, and Google Hangouts set up for these emergency situations."

"I was asked to solve our issue of employee turnover which ended up being much more difficult than I originally thought. My initial goal was to improve turnover by 70% but in the end, only reached 40% improvement. Although I did not reach my goal, I am still happy that my action plan made a difference."

"I had a customer who was not happy with my delivery, and I chose to take care of the situation without involving my boss. It wasn't that I was trying to sweep the situation under the rug, I just honestly thought I had been successfully dealing with the situation on my own. Unfortunately, I was wrong because the client sent a nasty email to my boss a short time after. I should have gone to my boss right away and filled him in. It's something that I've learned from, and I'm ready to involve my boss with every sticky client situation."

"In a previous role as a personal shopping assistant, I was tasked with taking on a notoriously difficult client. She spent a lot of money in the store in the past but was very demanding. This challenge seemed like the perfect opportunity to prove myself. A few months in, I made the misstep of mentioning something she'd complained about at an earlier date. Apparently, she was offended that I brought it up, even though I meant it very innocently. I owned up to it immediately to my manager and came up with a plan to win her back. I wrote a snail-mail card apologizing to her and let several weeks pass before reaching out in any other way. By the time I did, two months later, she was perfectly lovely, dismissed my apology as though she didn't know what I was talking about, and we moved along in a better fashion than we had prior."

"In my first role out of college, I was working to solve a lane issue with a carrier that kept falling through. I went through every solution I could come up with including pitching consistency, to leveraging my current relationships, and asking for favors. Those favors and workarounds ran out, and we fell short of client expectations. While I did all that I knew how at the time, I still fell short, and it was disappointing. In retrospect, I would have involved more people in supervisory positions earlier on in the process to learn from their shared experiences."

"The problem I've failed to solve that still keeps me up at night is a successful inclusion of one of my students with an IEP. He loves Spanish and in a one-on-one setting excels at it, but cannot handle the behavior expectations in class because he gets too excited. I've tried multiple approaches to get him to regulate, and participate, but so far nothing has allowed him to participate in the class without disrupting the other students and causing a meltdown for himself. This fact weighs on me since I want him to experience inclusion at all times. As a result, he comes to my office a few days each week, and we have our Spanish class together. I feel this exemplifies who I am as a teacher. I will go the extra mile for my students to make sure they get their fair shake at life."

12. What sources do you look to when you need to solve a complicated problem?

The interviewer wants to know that you can think outside the box, or even ask for help when you are stuck on a complicated problem. Maybe you look to a mentor or boss for advice. Perhaps you have handbooks, manuals and systems you turn to for help. Offer some relevant examples based on your industry. If you work in the medical field, you may turn to textbooks, online research, colleagues or even patient's history to find the right solution. If you work in customer service, you may ask the customer what they need to find the best way to solve the problem. Show the interviewer that you are knowledgeable and equipped to handle these types of scenarios.

"When I am faced with a complicated problem, I will look to the resources that my current company has provided me. The answer is almost always in there. If it's more of a moral dilemma vs. a knowledge-based dilemma, I will ask my supervisor for his thoughts and opinion since I value him as a mentor and expert in our industry."

"I have a variety of manuals and online tutorials that I lean to when I need to solve a complicated problem. Usually, the issues are surrounding Excel troubleshooting, so it is easy to find answers without involving anyone else and interrupting their day."

"I have a business mentor that I turn to for significant problems. She and I are in the same industry; however, she is much more tenured than I am. I recommend that everyone have a mentor. Even though I run a team of my own now, there are times when I do not have the answers."

"When I need to solve a complicated problem I will turn to marketing forums and blogs that I follow. There is a plethora of information on the internet, and it would be a shame not to take advantage of them!"

"To solve a complex issue, I will reach out to a manager or mentor from a previous role to ask them how they've handled such issues in the past. I am always ready to dive back into our handbook, but these types of scenarios are often not covered there, which is why I value a human, experiential approach. I know that there are so many folks in the industry who have so much to teach me and have probably already "been-there-done-that," so I love to utilize them as a resource."

"If there's a complicated problem, I'll write out what I think the possible solutions would be. Then, I will weigh those potential solutions against one another and list the complications that may arise as a result of each choice. Also, I am always open to input or suggestions from those with more experience than I. I will often turn to my organizations' training resources, as well as talk the problem out with coworkers or my boss."

"I have a vast cohort of teachers with whom I work currently, or have worked in the past, so if I am stuck on a problem or feel I need some additional help, I reach out to these educators. If nothing else, they're there to lend an ear and let me bounce my ideas off of them. They almost always have some real-life experience in a very similar situation. I value this collaborative, supportive group that I've amassed over the years."

13. After you implement a solution to a problem, how do you test the effectiveness of that solution?

The interviewer wants to see that you have strong follow-through skills and the ability to use data and analytics to support your decisions. The only way to test the effectiveness of a new solution is to keep a close eye on the immediate, and often longer-term, results! Depending on the situation, you can use data, run reports, and compare/contrast your findings. If you have records of the data before your problem-solving solution, you can track the results of your new solution and analyze in a month, or beyond. It can take time to see the results, so having a method for measuring them is essential. Give an example of a time you implemented a solution and found a way to measure the results to check its efficacy.

"Last year, our company was having a very high rate of turnover due to employee burnout during overtime hours worked. I implemented a third shift which alleviated the need for excessive overtime. Yes, it did increase our payroll costs by 33%; however, it decreased our turnover which was costing us more and more every year. From the analytics I have been watching, the change will pay for itself by the end of year two."

"One solution that I recently implemented was the use of Google calendar with the executive that I support. She was rarely updating her Outlook calendar because she found it to be too difficult to do on her smartphone. Since this implementation, we have minimized our crossed wires significantly! I have measured the effectiveness of this new calendar strategy by marking down any appointments that need to be rescheduled. So far, for the month, the number of reschedules is down by 80%."

"I always look at the data to gauge the efficacy of policy or new solution. I am big on numbers as they do tell the full, and true, story. I love the reliability of spreadsheets and numbers!"

"Once our team comes up with a new marketing strategy for a client we will conduct two focus groups. One test group will be on the original marketing plan and the second, on the plan that we want to pitch. The use of focus groups is the best way for us to measure if our new strategy will be effective enough to justify the changes for the client."

"I like to collect data, as well as anecdotal assessments of new policies. It's great to have data to confirm if it was or was not effective, but I am a firm believer, too, in getting the team on board. Plus, as you implement a solution, sometimes those doing the actual day-to-day work with customers or in the actual implementation have a more accurate understanding of what's going on or what could be improved. Therefore, I am sure to ask the staff how they think it's going, if it's impactful, or what they still see as an area for growth."

"To test the effectiveness of any solution, you have to be objective and see if it genuinely addressed the problem it set out to solve. Everything in our business runs on KPIs, so when we introduce any initiative, we can see how it is or is not impacting those measurements. One example of this was when I assigned specific accounts to my team of buyers, instead of just attaching as they came up. The idea was to get a buyer to become an expert on that account, their buying habits, and therefore be more effective in the long term at sourcing for their needs. At first, it didn't seem all that impactful, as the close rate was still around 42% overall. However, over the course of 10 weeks, we saw an uptick in close ratios on the assigned, dedicated accounts versus the randomly distributed ones, resulting in 53% close ratio. It's something that became so effective that other sales pods adopted it as their practice as well."

"For me, numbers play an important part in teaching but do not paint the full picture. So, after implementing a change, it is certainly important for me to collect data from our unit tests to gauge the efficacy of the lessons we're teaching and the lesson plans we are using. However, I also am sure to check-in with the students on a more regular basis to check for comprehension. Testing is only truly reflective of the way some students learn, whereas others are terrible test takers, even though they've learned the material. That is why I like to take a two-pronged approach."

14. When a major problem arises, what is your first reaction?

The interviewer wants to know if your reactions to problems reflect maturity and professionalism. How you react will significantly determine how you fit with their existing team. Perhaps your computer crashes, and you realize you may have just lost all of your hard work. Or maybe you are limited on time and have a deadline rapidly approaching. Demonstrate to the interviewer that you take a very methodical approach to problem-solving, rather than reacting impulsively when a problem occurs.

"When a major problem arises, my first instinct is to take a step back and absorb what just happened. I then go into 'brainstorm' mode, jotting down potential ways to resolve the issue. From there, I can use a pros and cons list to determine the best course of action for a fast and amicable resolution."

"I have taught myself to become much calmer with my first reactions when problems arise. Now, I will step back and review my options for solving the problem rather than allow myself to become frustrated. If I feel that I cannot solve the issue on my own, I will ask for help from my superiors."

"Depending on the situation, I will gather my resources and team and collaborate on making the necessary happen on a shortened timeline so that we can deliver our results in the most efficient manner possible. Usually, we learn something about ourselves, the team, or a more effective approach to the next problem in the process."

"When a major problem arises, my first instinct is to jump in and fix the issue. I am a do-er and also think in a reverse-engineering manner. I start with the desired result, and work my way backward from there, figuring out where the snag occurred."

"I am resistant to stress but cannot completely avoid it. When a major issue arises, I will take a quick walk, if possible, so I can best assess how to address the issue while clearing my head. Then, I get to work. I delegate whenever possible so that I can oversee the effectiveness, but am not at all afraid to jump in and do the dirty work myself."

"In the event of a significant problem or setback, my first reaction is to freeze in disbelief for a moment or two while I gather myself, then I jump into action. I know that I need to work harder and faster to recover the time and effort lost. My salesperson mind goes into overdrive until the issue comes to a resolution."

"My first inclination in the event of a major problem is to roll up my sleeves and jump in to fix it or help mitigate some of the potential blow out. This initial reaction is especially true when the problem involves a student's feelings or wellbeing."

15. What steps do you take when you have to make an immediate decision without all the relevant information?

Sometimes we have to make decisions without all of the pertinent information at our fingertips. The interviewer wants to know that you are capable of taking educated guesses and that you are confident enough in your abilities that you can make a firm decision without all pieces of the problem being present.

"When I need to decide without all of the information, I weigh the pros and cons and come up with a solution that makes the most sense. Common sense can take you a long way! Next, I may ask the opinion of someone I trust to see what they think. Even though I trust my decision-making ability, I still think it's important to get a second opinion when it comes to situations involving money or decisions that make a significant impact on others."

"Being organized, I do have a checklist that I follow on all policy-related decisions and changes. If I do not have all necessary information to make an important decision, I can usually find answers in our company resource database, or I will consult an administrator more tenured than I."

"Immediate decisions are required of me on a daily basis. For instance, what do I do when a forklift driver doesn't show up for their shift? How do I react to a chemical spill in the warehouse? I find that the most effective method for making immediate decisions is to forget about what you don't know and focus on what you do know. That's the best anyone can do, and there is no sense wasting time on the what ifs, especially in my industry when the safety of others could be at risk."

"In my current company, we have a rule always to do what will make the client happiest. So, when I am in a situation where I need to make an immediate decision on a client file, I will ask myself what I would want if I were the client. Then, I jump into action to make that happen."

"Often when a customer is worked up, I only have a piece of the puzzle to go off of, whether because they haven't given the full story, or I'm pulled in by the associate who heard the full story. In either case, it's something I'm accustomed to and deal with daily. As far as customer problems go, they tend to follow the same general pattern, so I assess quickly what category the problem seems to fall in, and go from there."

"I am a strong believer in following my gut, and for the most part, it has not steered me wrong. I try to gather as much information as possible, but when all of the pieces are not accessible, I assess the situation using my prior knowledge of similar situations, and I follow my intuition. If I'm not certain or feel conflicted, I don't hesitate to bring in another person to help me come to the best decision for the company."

"I feel comfortable making an immediate decision, even if I don't have all of the relevant information, for the most part. I have great confidence in my situational knowledge as an experienced educator. One example that comes to mind was the class when there was a behavior outburst. I immediately leaped into action to diffuse the situation the best way I knew. By acting quickly, I can prevent the situation from further escalating."

16. How do you deal with distracting coworkers who stand in the way of your progress?

Even the most well-meaning coworkers can distract you from getting things done at work from time to time. The funny and entertaining coworkers who like to chat online and send YouTube videos are often the ones who can get in the way of your productivity if you let them. How do you respond? Show off your ability to set professional boundaries, when needed.

"I typically just set a kind, but clear, boundary and tell my coworker that I need to focus. I will offer an alternate time for a catch-up, over lunch for example. It is important for the sake of workplace culture to set aside time to be social with coworkers, so I usually just let them know when I'll be available for a quick break in the day."

"I understand working relationships are significant, and I'm sure to make time for them so that I can be useful but also enjoy myself at work. With that said, I know where these relationships fall regarding prioritization of my day. I make sure that others know that, too, without being off-putting."

"I am always interrupted by my team - that is par for the course being a manager. To deal with any lost time, I will simply stay late or come to work a bit earlier the next day. My day is unpredictable, and I have accepted that fact."

"I am very open with my colleagues and will let them know if they are a distraction. Currently, I can take my work home as well so if there is a part that I cannot get past due to distractions; I will take a day to work from my home office."

"I try to make the workplace as fun as possible, within reason. I love to make it a place people want to go to, instead of dread. That said, there are always the people that ruin it for the rest of the team by taking advantage. To combat this, I make it very clear what the expectations of allowed and prohibited behaviors are, and am sure to reinforce those expectations."

"There are always going to be co-workers who are there for the gab, rather than the work, or who are content just being in their position with no intent of advancing through the ranks. Early in my career, this bothered me. Why weren't they motivated to grow and learn? Then, I realized that it's important to have those people since a company can't have all its people always vying for the top. If there's a distracting coworker, I try to make my priorities clear and engage kindly and courteously with them as humans, and then get back to work. I am sure to remain friendly, while also firm, as needed, to communicate that I am here for work first as a priority."

"Very rarely do I find that my coworkers successfully distract me- even in a department meeting, I find I'm able to remain on task. I was always taught to ignore the behavior you wish to cease. If my coworkers are distracting and seeking attention, I try to ignore it as much as possible and only address it when it's detracting from a productive work environment."

17. Tell me about a time when you had to troubleshoot to solve a problem.

Troubleshooting is like reverse engineering - it takes skill, effort, and patience. You have to understand the problem to know how to work backward from it to find a solution. Knowing how to solve problems with technical equipment is always a solid skill, and a great way to demonstrate your example. Show that you are insightful in your approach.

"Last week, while operating the ultrasound machine, I was receiving a repeated error. I entered in a few different codes, but that didn't solve the issue. I then did a hard reset, removing all power sources. Then, I referred to the online manual for additional suggestions. It took a little time and patience, but I was able to resolve the issue without calling a technician."

"We do not have an IT department in my current office so whenever an issue arises, I am the person that my team calls. Troubleshooting is fun for me - it's like a new challenge every time. Google and IT forums are often my best friend!"

"We had a major complication in our system and our entire production line shut down. Our network administrator could not be reached so I had to go old-school and manually enter the orders so that my team could continue with production. The entire debacle lasted half of a day, and my system worked well as a placeholder."

"One of our clients called me in a panic, saying that Facebook rejected their ad campaign that we so carefully crafted. I researched on ad policy forums and learned that it was not approved because we did not set our demographic targets to people only over the age of 21. The ad was for a craft beer company, and we did not put into consideration the legal age in most states. Once I was able to narrow down the issue, I tweaked the ad, and it was approved."

"One horrific day at work, our systems went down entirely. We had no backup for how to check customers out, so I had to dig in the deep recesses of the back room and find the card imprint machines, and we wrote out tickets by hand and made imprints of the cards. I tried all the usual tricks to get our registers up, but couldn't get them to come online as it was a network error. I found the way around it with the handprint cards and then opening the cash drawer with a key."

"In a troubleshooting situation, I approach it like a maze and work backward. There are usually multiple factors contributing to any one issue, so I try to discern what they are, weigh those out and try to conclude what the potential best solution is. As far as technically speaking, my go-to in many situations, as rudimentary and childish as it may be, is often turn it off and turn it back on. Ha. I know it sounds too simple, but it often works best."

"I do everything I can to test out the technology before I bring it into the classroom- the day is so packed that we don't have any time to spare on figuring out technology if it acts up. I also always have a backup plan in mind in case the smart board or whatever we're utilizing that day doesn't cooperate, so we don't lose precious learning time." However, I believe that troubleshooting applies to more than just technology. Problems that occur offline also need troubleshooting as they arise, including figuring out a lesson plan and how it works or doesn't. It's all about working backward to see what issues, if any, may arise in its implementation during a dry run. By preparing in advance and being aware of what issues may come up, I'm able to flush out problems that would have otherwise arisen during the class time. "

18. Tell me about a time when your analysis of a problem was deemed to be incorrect. What would you have done differently?

Everyone makes mistakes when analyzing a situation. The interviewer isn't concerned with perfection; instead, they want to know how you deal the aftermath of rejection! Sometimes you can't correct your mistakes, but you can certainly learn from them. Highlight your ability to learn from your mistakes and move on, professionally.

"It was my first job as a physician's assistant, and I was trying to diagnose a patient who had severe pain in her abdomen. After running some tests, the doctor and I believed she was suffering from a gallbladder problem. We treated her, but she came back to the ER a week later. It turned out she had a problem with her pancreas. Even though we misdiagnosed her initially, we were able to use this mistake to help us identify the real problem. I've learned that sometimes making a mistake is a part of the process of solving a more complicated problem."

"I was asked recently to work on balancing an accounts receivable report. Math is not my strongest suit; however, I was confident in my ability to make it happen. Through a bit of research, I carefully worked on the document and was quite proud of my result. It turns out, I skipped a few important steps, and my work was, in fact, incorrect. I took it as a learning opportunity but also realized that my strengths are in other areas of business. I should have asked for the project to be placed with someone else, but I do not regret trying."

"We had incredibly high turnover rates when I first started in my current role. Going in guns blazing, wanting to make a strong first impression, I did a complete overhaul of the training manual thinking that was the problem. It turns out the training manual was just fine. The culprit to the turnover was one employee who was a complete bully on the job. The moment I terminated that person, the issue was solved. At least now I have a fancy new training manual! Moving forward, I now poll my team regularly for job satisfaction. I encourage a transparent workplace culture where people feel safe bringing their issues to me."

"I had a client, earlier in my career, who was not seeing the same results from their Facebook advertising as they once did. I changed the headlines, increased the budget, and even did multiple A-B tests. What I failed to see were the strategic algorithm changes that Facebook had made, which directly affected the visibility of my clients' ads. Now, I have alerts and subscribe to a couple of blogs solely dedicated to these changes, so I never miss a beat."

"Unfortunately, this happened not too long ago where I misjudged a customer complaint. The associate needed to escalate the conflict to a manager but did not accurately portray the customer's concern, and I jumped into action based off of the limited information given. Due to not gathering enough information from the customer herself or clarifying the misunderstanding with the associate, I took a misstep with the customer and did not resolve the issue as quickly as I would have liked. Ultimately, I was able to clarify the situation and get to a resolution that worked for everyone, leaving the customer happy. However I have some regrets. It was a learning process, and something I have been sure not to repeat since. Were I to do it again, I would clarify the situation with the customer, rather than taking the associate's word for it."

"When pitching an existing client on increased volume next year, I had made a recommendation on the most effective carrier for a lane. I based this recommendation on historical data and projected future rates. However, a merger occurred after the time of the pitch, and their prices skyrocketed since they were the only viable carrier for that area. Without competition, they didn't have to remain competitive in their rates. While I could not have predicted the merger, I could have quoted out with a higher margin on our part so that if there were some snag like this, we are covered. Since we lock in the rates for the customer, we took a loss each time they moved freight this way. As a backup method, whenever possible, I attempted to send the freight another way, so that we would lose some money but not take as large of a hit. That was a big learning experience for me and has helped me be better prepared to pitch other customers in a more effective, CYA type way."

"While teaching, the kids told me that I needed to quiet down at one point. I assumed it was the teacher whom I shared a wall with, that planted the seed, which was irksome. This type of situation had happened before. This time, however, I was wrong. I asked her to avoid delivering messages to me through the students, and she said she had not. Apparently, the students knew she had a headache that day, so they were all watching their volume level. I was glad that I did address the situation with the teacher, but made sure not to be accusatory or make assumptions about motives again."

19. Tell me about the most challenging aspect of your previous job. How did you overcome it?

Sometimes the most significant workplace challenge is a difficult task that puts you outside of your comfort zone. It could be something that requires skills you haven't mastered yet or qualities where you are not the strongest. Explain to the interviewer why it was difficult but be sure to spend more time highlighting the actions you took to overcome the challenge.

"The most challenging aspect of my last job was troubleshooting some of the older technology. We needed some serious upgrades, but they weren't in the budget. Learning how to work around this problem was quite a challenge, but I learned how by referring to old manuals and online forums. I ended up to become one of the stronger users of this program, in our entire office! I quickly became the go-to person when anyone had questions about the technology."

"In my current role, we have global offices that span four time zones. It is an incredible challenge to be continually calculating the difference in my mind when I call or email on updates for projects, for instance. I now have each locations time added to my desktop, my smartphone, and four individual clocks on my wall. These small and inexpensive changes made all the difference."

"The most challenging aspect of my previous job was the constant need to pivot when it came to trends in the industry. We would gain footing, and then the next greatest product would arrive. It made it difficult to feel loyalty to any of it. I started to express loyalty to the company's ability to discern great products instead of narrowing in on the products themselves. This shift in thought helped with mine and my teams' performance when it came to sales."

"My previous role was with a small agency where budgets were always a concern by the clients. Although I liked the clients, they were usually independent businesses with less than ten employees. They had a hard time thinking big-picture. I overcame this by coming up with a questionnaire that would address their greatest pain points and needs for their business. I would then focus on their small goals versus what I felt their company could be. Some business owners are more comfortable being comfortable, versus ruling the world, and that's okay! I just needed to wrap my marketing brain around that."

"The most challenging part of my prior role was navigating the landscape as the newest manager on the team. I needed to work on gaining the trust and respect despite my being green. I worked hard to build individual relationships with each associate and forge a bond with them. I also shared information about myself, including my experience in the industry, and who I am as a person. I know that this made me more human, approachable, and also solidified my credentials, so I know how to get the team on my side."

"The most challenging part of my previous job was relying on another team to be efficient. I am all for teamwork, but for me to be paid, this team needed to deliver timely and quality work. Meanwhile, their goals and metrics remained disconnected to any sales outcomes. This situation made it tough to motivate them. In the short term, I sat down with them and explained why it was vital for myself them, and the company that we work together on the same timeline. I incentivized them with coffee or store gift cards. Bigger picture, I sat down with the management of both teams and shared the issues we were having, suggesting a solution that would tie their KPIs and financial incentives to our outcomes, to make them invested. In the end, the short- and long-term approaches proved useful."

"I think the most challenging aspect of my current job is the fact that I share a classroom with another educator. Without having my space, other obstacles come up such as teachers trying to influence how I run my class, or them holding small conversations with their aides during my teaching time. I make sure to address this up front with the classroom teachers- that while it is also their room, please treat it as though it were mine during the 40 minutes that I am teaching. If there is ever an issue, I am sure to address it quickly and directly, so we can move past it."

20. When faced with a problem, are you more likely to jump into solving it, or are you the type to carefully assess the issue first?

The interviewer would like to know more about your problem-solving skills, and your personality. Discuss how you tackle problems when they arise, and keep your answer work-related if you can. Whether you are the type to jump right into solving a problem or you are more methodical in your approach, highlight to the interviewer that you are capable of handling issues professionally while using sound judgment.

"When faced with a problem, I am more likely to jump right into solving it. I believe that you cannot leave a problem to fester or become bigger than it already is. You have to take ownership of the issue, and involve yourself in the resolution right away. With that said, I am responsible for my decision making and certainly don't jump in blind. If I am unsure of what action to take, I will ask my leader for advice."

"I am careful and calculated in every step taken when it comes to problem-solving. This effort is because as an administrator, one error in judgment can throw off the timing of an entire project. I would say that I am the particular type who thoroughly assesses situations."

"As a manager, responsible for a team of 18 individuals, I need to be very calculated in most decisions that I make. I cannot act on the fly, or by emotion alone because others are relying on me."

"In marketing, I feel that I often have to do both. Some smaller decisions simply cannot be over-thought and others, especially when it comes to strategy, will need extra thought. I can provide both sides when appropriate."

"I think it depends on the situation at hand, honestly. In a familiar situation, I am ready to jump right in and tackle the problem. However, when the stakes are high, or tension is high, I am more inclined to take a step back, slow down, and be more tactful in my approach."

"I'm a "roll up my sleeves" kind of person. I see a problem, envision a solution, and begin to tackle it, figuring it out as I go and asking for help along the way. I think it can become a 'bury your head in the sand' issue, or the team will have the bystander effect, thinking someone else is going to take care of it, so I jump in and take action. I rally the troops, gather the appropriate supplies or resources as needed, and get to work."

"I'm the type of teacher who jumps in, head first and gets the work done. I know that the longer I wait to address a problem, the bigger it becomes, so I make sure to get right to it. This approach applies to interpersonal issues as well as curriculum missteps."

21. Give me a recent example of a valuable lesson you learned from a problem you faced at work.

One of the best aspects of problem-solving is that you always have the opportunity to learn from the experience. Seeing problems as opportunities to grow, is what makes you an excellent employee! Show the interviewer that you can learn valuable lessons when there is a problem at hand. Use a work-related example, if you can.

"Last month our sales team was facing a major challenge when we lost one of our primary distributors. I took action and started cold-calling, other potential distributors. I brainstormed with my team in some other ways that we could avoid a negative impact on our bottom line. We were quite successful in our recovery, and I would say that the biggest lesson I learned from the experience is that you are often only successful if you have motivated people in your corner."

"The most valuable lesson I learned from problem-solving at work is that not everyone will see your solution as the best one. Accepting change is difficult for some people, so I have found that not everyone will be on board right away."

"I recently had an employee express their disinterest in the job and the company. Rather than coach them out, I selfishly wanted to 'save' the employee. I put in extra hours mentoring and training her, just to see her quit anyways. It's a valuable lesson as a manager to put your energy into those who want to be there. Other efforts are often just a temporary fix for the inevitable."

"Marketing is always shifting so I often learn new, valuable lessons. One lesson I recently learned was to double check the documents that I send out for any needed updates. A lot of the manuals and how-tos that we send clients are evergreen; however, some are not. I accidentally sent an old social media guide to a client, and they ended up being incredibly confused. My lack of attention to detail at that moment was a bit embarrassing but lesson learned!"

"A recent learning experience was when I misjudged what the customer was upset about, and I didn't take the time to learn what it was that she was looking for. It reminded me to slow down, go back to the basics, and not assume that all situations fit the mold of the 'typical' customer. It was a perfect reminder that though I've seen most everything, I need to remember that each person and situation is unique."

"A recent valuable lesson for me has been not putting all of my eggs in one basket, as the old saying goes. Over 64% of my sales came from one group of stores, and they've always been a big contributor to the entire company's sales numbers. However, they were put on "hold" recently by their corporate, due to some restructuring issues. This event threw me for a loop. I was in real danger of not hitting my monthly sales target, and therefore I would have fallen short on my quarterly quota as well. I had to work extra long hours and hustle my other clients and fence-sitters to get them into "buy" mode to make up for the void in my numbers. It took a ton of effort, long nights, and creative pitches, but I was able to make up for the gap. I learned just how important it is to diversify my portfolio so that I don't find myself, or the company, in this position again."

"When working on curriculum development, I learned an important lesson. Two of our teachers wanted to keep a lesson in, because of personal connections to the lesson, but the other three were quite against it, with me being the uncertain one. I saw the validity in both sides. So, rather than find ourselves with a divisive issue on our hands, I proposed that we have a "freebie" lesson when we each got to pick one that we thought would culturally enrich our students. I learned that by thinking outside of the box, the team and our students would all benefit."

22. When change occurs in the workplace, it can create new problems. Do you see these as inconvenient problems, or opportunities to learn?

When a change occurs in the workplace, often problems arise due to new implementations and procedures, or unforeseen kinks needing to be worked out. Do you approach these problems positively or do you resist the change? Talk to the interviewer about how you can adapt to the inevitable issues that come with the change in the workplace.

"I fully understand that when the change occurs in the workplace, some new problems may arise because of it. I embrace workplace change because it often gives me the opportunity to learn a new skill or even teach a colleague a new skill."

"As an executive assistant, I see change all the time. Policy changes, travel changes, issues in scheduling, and the like. Although they are often inconvenient or threaten to throw my day off, I am always prepared with a Plan B. Each time these situations occur, I learn something new."

"Change is inevitable when you work with people because you cannot control everyone's reactions in a day, or whether they even show up to work. Recently I had a major shift in my team and, overnight, went from being completely confident in my team to the need of reassessing our strategy. I saw this as an opportunity to stretch outside of my comfort zone. I embrace change and learning opportunities."

"One change that we always go through in this industry are shifts related to social media platforms and online trends. These tools are ever evolving, and when you think you have it - poof - changes are made. I don't mind this, however. I believe that each shift is a chance to learn something new."

"I like to approach every day and situation as an opportunity to learn and grow, so even though it's uncomfortable, I like to think that there's something valuable to take away from any situation that involves change."

"I'm all about taking everything in stride and jumping on opportunities for growth and improvement. My latest job has been a year-long exercise in that: a start-up that pivoted entirely from the direction it had been going in when I was brought on, with an entirely new team and even intended client base. I decided to take it as a growth opportunity. I took a deep breath, rolled up my sleeves, and got to work learning and adapting to the new product, clients, and management. I think that the experience will serve me well in the future since I became quite flexible and learned a lot about myself and sales in the process."

"I am adaptable to change. As a teacher, I have to be open to change! Nothing stays the same in education and students challenge everything. I am capable of pivoting when needed and am not thrown off my game, easily."

23. Rate your problem solving skills from 1-10. How do you justify your rating?

The interviewer wants to know how you would rate your problem-solving skills. Of course, you want to give yourself a healthy rating; however, it's crucial that you remain realistic. Try to avoid giving yourself a 10, and nobody is perfect, and you do not want to come across as overly confident or someone who has no room for feedback and improvement. Alternately, avoid giving yourself too little credit. You do not want to paint the picture that you are a problem-solving dud! Try to remain in the 7.5-9.5 range while staying honest and accurate. Everyone has room to learn and improve! Be sure to justify your score as well.

"I rate my problem-solving skills as an 8/10. I will, on occasion, have times when I am not as efficient as I would like to be but all in all, I do feel that my problem-solving skills are above average. My supervisor and co-workers will attest to my fast reflexes when a problem arises, and they would also say that I remain calm under pressure."

"I will rate myself an eight because I value problem-solving but, just like most people, I have things to learn. Some ways to ensure that I can effectively solve issues are by utilizing multiple knowledge resources when looking for answers."

"I will rate myself an 8.5 because I consider myself a strong problem solver, especially when it comes to important matters that affect my team. Solid problem-solving skills are the foundation of success in business. I am always striving to be a better problem solver, so I leave the rest of the scale as an aspirational measure."

"Problem-solving is at the heart of what we do in marketing. We have to solve branding and sales issues for our clients all the time. I am an exceptional problem-solver, and quite creative with my strategies. For that reason, I will rate myself as a 9/10 and always improving."

"I'd rate my problem-solving skills as an 8/10. I believe I'm always a willing learner who brings creativity to the table, no matter what the situation. I am still full of ideas on how to solve a problem, and yet I am also open to the opinion and input of others. I like to collaborate but am not afraid to take charge and make it happen. There's room for growth, which is why I give myself only an 8!"

"I would say I get a solid 8.3 on a scale of 10. Seems weird to give myself something like a .3, but I think of it as an 83%, which is a B minus teetering on a solid B. It's a solid grade, with definite room for improvement, since I'm certainly not perfect. The reason for the B-/B grade would be that I'm quick to take action and figure out the solution as I go, but sometimes I could benefit from taking a moment to pause and reflect or gather other contributors before taking action. That said, I believe I get the best outcome possible when faced with a challenge."

"I would say I'm a strong problem solver and would rate myself an 8/10. I follow my gut and problem solve creatively, but know there is still room for improvement. I think my teamwork and problem strategies highlight my strengths in problem-solving. I can hear what people find essential and flush out the things on which we can compromise. Then, I come up with a great outcome that makes the teachers happy and is in the best interest of our students."

24. What do you think might be the greatest challenges faced in this job? How will you overcome these challenges?

Even though it may seem like a dream job, the interviewer wants to know that you have realistic expectations of the role and that you will not be blindsided if problems or challenges present themselves. Keep your answer simple. It is okay to ask for clarification on the position if you do not fully understand what challenges are in store for you.

"I think the greatest challenges in this role will be to learn the proper operation of the equipment. Another challenge will be the physical aspect of the position as I will be required to stand and walk around most of the day. I will be sure to pay keen attention to training and ask questions along the way. In regards to the physical component - I will get used to the additional activity after just a couple of days, I'm sure."

"I believe that the greatest challenge in this job will be to learn the ins and outs of your systems. I am familiar with SAP; however, will need to navigate some modules that will be new to me. If you don't mind, I would like to gain a head start on these by studying online for the next weekend or so."

"As a new manager, the biggest challenge is always to earn the trust of my new team. I plan to do this by getting to know everyone through genuine interest and conversation. I do understand that solid trust develops over time, but it's important to me to get started on the right foot."

"The greatest challenge is going to be getting to know your clients and their preferences. Every client has their quirks that need to be kept the top of mind during projects. I plan to read as many project notes as possible before diving into face-to-face meetings. I intend to come across to your clients as well-prepared and earnest."

"I think the added responsibility of running one of the highest volume departments in the store will be an adjustment, but it's a welcome challenge. I am looking forward to tackling it head on and growing through the challenges, because I know on the other side of those challenges, of that responsibility, lies the biggest opportunity yet."

"I would say the greatest challenge I'll face in this role is learning the industry ins and outs to be perceived as an expert when making the pitch to new clients. I want to be sure to immerse myself in the industry jargon, attend as many seminars and conventions as possible, and I've already begun subscribing and reading the leading industry publications so that I can get into the nitty-gritty of how it all works. Of course, I will also seek out mentorship opportunities where I can learn from folks who have been in the industry for years. I find they love to share their knowledge and it gives me a leg up."

"I believe the greatest challenge faced in this new position would be getting accustomed to the new curriculum. I am accustomed to my lesson plans and the curriculum I've had a hand in developing over the last ten years, so something new will have a bit of a learning curve, but welcomed. I am looking forward to a new challenge and to tackle a new set of lessons!"

25. What steps do you take to solve a problem?

The interviewer would like to know that you understand the importance of taking calculated steps when problem-solving in the workplace. Most candidates want to sound like go-getters, and their first instinct would be to say that they jump right in. Jumping right in can cause costly mistakes and oversights. Assure the interviewer that you will workshop the issue before diving in! Here are some steps to take: 1. Identify The Problem. Proper problem solving involves ensuring that you are very clear on the nature of the problem. Be sure that you fully understand the core of the problem before trying to repair it. 2. Identify The Stakeholders. Ask yourself, what the best case resolution will be for all stakeholders, not just for yourself. Ask yourself what is best for the company, your coworkers, and your clients. 3. List Your Options. The third step is to figure out what your options are when it comes to your course of action. Write them down if you need to. 4. Evaluate Your Options. Take a look at your list of potential actions and see if you can solve the problem using just one, or a blend of them. 5. Execute! Finally, execute your well-researched action plan. Be sure to set up a follow-up time to ensure that your solution worked.

"When I need to solve a problem, I first stop to ensure that I understand the issue at hand. Once I do, I will think of potential fixes and the pros and cons of each. Whichever solution or a blend of solutions is best for the customer; I will choose that option."

"My current company is very team-focused, and we train everyone to problem-solve with "what is best for team morale" being the question at hand. I have been with the company for twelve years so most problems I have a pretty clear idea of what will work for us, but when I need to workshop an idea, I will call in my team and have a brainstorm session."

"Problem-solving in Marketing can be unique because you have to truly balance the customers' pain point with the solutions that are currently available. Also, some clients like trying new marketing methods and others want to remain conservative, using only tried and true advertising methods, for instance. When I approach a problem, I first identify the personality of the client and their business and research options from there."

"Problem-solving in a retail environment is challenging in the sense that the issue is often something that needs to be fixed immediately, like a faulty product or an upset customer. When faced with a problem, I ask questions first, to ensure that I fully understand the core of the issue. Once I fully understand the core of the problem, I can more easily troubleshoot from there."

"Every customer is different, with unique needs, so when I need to problem-solve, I am often coming across a brand new problem or a different version of a problem I have seen before. Our company is big on chasing the money, and so I have been trained that every solution I choose must have the business' bottom line top of mind. My process is to understand the issue, address who the stakeholders are, and create a solution where everyone feels they won in some small way."

"Problem-solving in the classroom is a challenge because it is often on the fly. Or, a student will ask a question in a new way and I won't necessarily have the answer! When a problem arises, I like to involve my class, have a brainstorm session, and discuss as a group what we could do. This method turns an issue into a conversation where we have the opportunity to come up with some unique solutions."

26 Good Examples of Problem Solving (Interview Answers)

By Biron Clark

Published: November 15, 2023

Employers like to hire people who can solve problems and work well under pressure. A job rarely goes 100% according to plan, so hiring managers will be more likely to hire you if you seem like you can handle unexpected challenges while staying calm and logical in your approach.

But how do they measure this?

They’re going to ask you interview questions about these problem solving skills, and they might also look for examples of problem solving on your resume and cover letter. So coming up, I’m going to share a list of examples of problem solving, whether you’re an experienced job seeker or recent graduate.

Then I’ll share sample interview answers to, “Give an example of a time you used logic to solve a problem?”

Problem-Solving Defined

It is the ability to identify the problem, prioritize based on gravity and urgency, analyze the root cause, gather relevant information, develop and evaluate viable solutions, decide on the most effective and logical solution, and plan and execute implementation. 

Problem-solving also involves critical thinking, communication, listening, creativity, research, data gathering, risk assessment, continuous learning, decision-making, and other soft and technical skills.

Solving problems not only prevent losses or damages but also boosts self-confidence and reputation when you successfully execute it. The spotlight shines on you when people see you handle issues with ease and savvy despite the challenges. Your ability and potential to be a future leader that can take on more significant roles and tackle bigger setbacks shine through. Problem-solving is a skill you can master by learning from others and acquiring wisdom from their and your own experiences. 

It takes a village to come up with solutions, but a good problem solver can steer the team towards the best choice and implement it to achieve the desired result.

You can share all of the examples above when you’re asked questions about problem solving in your interview. As you can see, even if you have no professional work experience, it’s possible to think back to problems and unexpected challenges that you faced in your studies and discuss how you solved them.

Interview Answers to “Give an Example of an Occasion When You Used Logic to Solve a Problem”

Now, let’s look at some sample interview answers to, “Give me an example of a time you used logic to solve a problem,” since you’re likely to hear this interview question in all sorts of industries.

Example Answer 1:

At my current job, I recently solved a problem where a client was upset about our software pricing. They had misunderstood the sales representative who explained pricing originally, and when their package renewed for its second month, they called to complain about the invoice. I apologized for the confusion and then spoke to our billing team to see what type of solution we could come up with. We decided that the best course of action was to offer a long-term pricing package that would provide a discount. This not only solved the problem but got the customer to agree to a longer-term contract, which means we’ll keep their business for at least one year now, and they’re happy with the pricing. I feel I got the best possible outcome and the way I chose to solve the problem was effective.

Example Answer 2:

In my last job, I had to do quite a bit of problem solving related to our shift scheduling. We had four people quit within a week and the department was severely understaffed. I coordinated a ramp-up of our hiring efforts, I got approval from the department head to offer bonuses for overtime work, and then I found eight employees who were willing to do overtime this month. I think the key problem solving skills here were taking initiative, communicating clearly, and reacting quickly to solve this problem before it became an even bigger issue.

Example Answer 3:

In my current marketing role, my manager asked me to come up with a solution to our declining social media engagement. I assessed our current strategy and recent results, analyzed what some of our top competitors were doing, and then came up with an exact blueprint we could follow this year to emulate our best competitors but also stand out and develop a unique voice as a brand. I feel this is a good example of using logic to solve a problem because it was based on analysis and observation of competitors, rather than guessing or quickly reacting to the situation without reliable data. I always use logic and data to solve problems when possible. The project turned out to be a success and we increased our social media engagement by an average of 82% by the end of the year.

Answering Questions About Problem Solving with the STAR Method

When you answer interview questions about problem solving scenarios, or if you decide to demonstrate your problem solving skills in a cover letter (which is a good idea any time the job description mention problem solving as a necessary skill), I recommend using the STAR method to tell your story.

STAR stands for:

It’s a simple way of walking the listener or reader through the story in a way that will make sense to them. So before jumping in and talking about the problem that needed solving, make sure to describe the general situation. What job/company were you working at? When was this? Then, you can describe the task at hand and the problem that needed solving. After this, describe the course of action you chose and why. Ideally, show that you evaluated all the information you could given the time you had, and made a decision based on logic and fact.

Finally, describe a positive result you got.

Whether you’re answering interview questions about problem solving or writing a cover letter, you should only choose examples where you got a positive result and successfully solved the issue.

Example answer:

Situation : We had an irate client who was a social media influencer and had impossible delivery time demands we could not meet. She spoke negatively about us in her vlog and asked her followers to boycott our products. (Task : To develop an official statement to explain our company’s side, clarify the issue, and prevent it from getting out of hand). Action : I drafted a statement that balanced empathy, understanding, and utmost customer service with facts, logic, and fairness. It was direct, simple, succinct, and phrased to highlight our brand values while addressing the issue in a logical yet sensitive way.   We also tapped our influencer partners to subtly and indirectly share their positive experiences with our brand so we could counter the negative content being shared online.  Result : We got the results we worked for through proper communication and a positive and strategic campaign. The irate client agreed to have a dialogue with us. She apologized to us, and we reaffirmed our commitment to delivering quality service to all. We assured her that she can reach out to us anytime regarding her purchases and that we’d gladly accommodate her requests whenever possible. She also retracted her negative statements in her vlog and urged her followers to keep supporting our brand.

What Are Good Outcomes of Problem Solving?

Whenever you answer interview questions about problem solving or share examples of problem solving in a cover letter, you want to be sure you’re sharing a positive outcome.

Below are good outcomes of problem solving:

• Saving the company time or money
• Making the company money
• Pleasing/keeping a customer
• Obtaining new customers
• Solving a safety issue
• Solving a staffing/scheduling issue
• Solving a logistical issue
• Solving a company hiring issue
• Solving a technical/software issue
• Making a process more efficient and faster for the company
• Creating a new business process to make the company more profitable
• Improving the company’s brand/image/reputation
• Getting the company positive reviews from customers/clients

Every employer wants to make more money, save money, and save time. If you can assess your problem solving experience and think about how you’ve helped past employers in those three areas, then that’s a great start. That’s where I recommend you begin looking for stories of times you had to solve problems.

Tips to Improve Your Problem Solving Skills

Throughout your career, you’re going to get hired for better jobs and earn more money if you can show employers that you’re a problem solver. So to improve your problem solving skills, I recommend always analyzing a problem and situation before acting. When discussing problem solving with employers, you never want to sound like you rush or make impulsive decisions. They want to see fact-based or data-based decisions when you solve problems.

Next, to get better at solving problems, analyze the outcomes of past solutions you came up with. You can recognize what works and what doesn’t. Think about how you can get better at researching and analyzing a situation, but also how you can get better at communicating, deciding the right people in the organization to talk to and “pull in” to help you if needed, etc.

Finally, practice staying calm even in stressful situations. Take a few minutes to walk outside if needed. Step away from your phone and computer to clear your head. A work problem is rarely so urgent that you cannot take five minutes to think (with the possible exception of safety problems), and you’ll get better outcomes if you solve problems by acting logically instead of rushing to react in a panic.

You can use all of the ideas above to describe your problem solving skills when asked interview questions about the topic. If you say that you do the things above, employers will be impressed when they assess your problem solving ability.

If you practice the tips above, you’ll be ready to share detailed, impressive stories and problem solving examples that will make hiring managers want to offer you the job. Every employer appreciates a problem solver, whether solving problems is a requirement listed on the job description or not. And you never know which hiring manager or interviewer will ask you about a time you solved a problem, so you should always be ready to discuss this when applying for a job.
