The Best 40 Help Desk and Desktop Support Interview Questions and Answers

As businesses worldwide adopt IT and software systems, the demand for desktop support and help desk professionals is increasing. Millions of users face daily issues with their computers.

These issues affect productivity, so companies want to ensure that their IT systems run smoothly. That’s why they need desktop support and help desk professionals.

Desktop support and help desk interviews check your technical knowledge and problem-solving skills. The main focus however, is on your problem-solving approach, customer service, and communication skills.

If you have a desktop support or help desk job interview, here are the best 40 interview questions and answers you should use to boost your chances of getting the job.


Question #1 &#;Why do you want to work as a desktop support specialist?

Your answer should indicate that you have a real knack for solving problems.

Instead of just saying desktop support is my “passion”, try to be original and answer the question in such a way that the interviewer feels that you really enjoy solving computer problems.

So, a good answer would be:

I’ve loved solving computer problems since I was a child. I remember opening my childhood computer and toys to look at what’s going on inside them, and I tried to understand how they worked.

I think desktop support provides me an opportunity to refine my problem-solving skills in the area of IT.


Question #2 &#;Give us an example of a ticket that you resolved. What was the problem and what steps did you take to solve it?

This is a very common question in desktop support and help desk interviews.

Try to be genuine and give a real-life example of a ticket you’ve resolved at any point in your career.

The interviewer wants to know your problem-solving approach and your communication skills.

If you have never solved an IT ticket before, you can familiarize yourself with a few common computer problems and their solutions before going into the interview.  You can use one of these examples to answer this question.

If you have solved an IT ticket before, here’s a good answer to this question:

In my previous company, I was assigned a ticket in which a user was not able to drag and drop anything on their desktop.

I contacted the user remotely, as they were located in a different office.

I asked them to restart their computer, but the problem wasn’t fixed.

I asked the user to look at their keyboard and make sure that no key was pressed.

It turned out that the Escape key on the keyboard was pressed due to some stickiness. Bringing the Escape key to its normal position fixed this problem.


Question #3 &#; You receive a ticket in which a user’s monitor is not working. How will you solve this problem?

I will first check the power cable and then the VGA or DVI cables and ports to rule out any hardware issues. After that, I will connect a spare monitor, if available, to the computer to make sure the monitor itself is not faulty.

I will also check the display drivers and video card.


Question #4 &#; What is Safe Mode?

Safe Mode is used to start a computer in the most basic state. In Safe Mode, the computer does not use autoexec.bat or config.sys files and most of the device drivers are also not loaded.

This helps in narrowing down the cause of a specific problem.  If a problem is not appearing in Safe Mode, it means the default settings and basic files have no problem, and we should look elsewhere to diagnose the problem.


Question #5 &#; What is Active Directory?

Active Directory is a service by Microsoft that is used to manage, organize and run networks.

Active Directory makes it easier for system administrators to find and use information related to all the users and objects in a network.

An example would be using active directory to assign new policies to a specific group of users, restricting access to a printer for a specific user, or removing users from a network.

Active directory consists of different objects, like forests, domains, contacts, groups, sites, printers, and subnets.

Question #6 &#; What is Blue Screen of Death and how do you fix it?

The Blue Screen of Death is a critical error that occurs when the operating system cannot function, and it crashes. Mostly, BSoD problems are related to hardware, kernel, or drivers.

Blue Screen of Death errors often show an error code or stop code which we can be used to find out the cause of the problem.

To solve this problem, I will first restart the computer. If the computer restarts successfully, I will update all drivers.

If the problem persists, I will disconnect all unnecessary hardware to rule out the external causes. I will also boot the computer in safe mode to see if the problem occurs in this basic state as well.

Other fixes I can try include, checking the hard disk for bad sectors, system restore, installing updates if available, checking hard disk cables, and using the startup repair option from the boot menu.


Question #7 &#; A user complains that their system is running very slow. How would you solve this problem?

The primary reason behind a slow computer is usually lack of sufficient memory.

I will start by removing temporary files from the Windows folder. I will also, with the user’s permission, delete any unused files and programs that are taking up significant space on the hard disk.

I will also run defragmentation tools to optimize space on the hard disk.

If the user is facing slow performance while using the internet, I will delete cache from the browser.

As a last resort, I’ll explore the possibility of upgrading the hard disk to SSD, increasing RAM, or installing a more powerful processor.


Question #8 &#; Describe a situation where you had an angry client or user.

Try to answer this question in a way that shows you are always patient, and willing to listen to the customer no matter how angry or unfriendly they are.

The interviewer is trying to test your ability to solve problems in tough situations.  For example, when a customer is being angry, impatient, irrational, or unreasonable.

The employer wants someone who is a good listener, problem solver, and has the ability to put themselves in another person’s shoes.

So, here’s how you should answer this question:

In my previous company, a user was extremely upset with his printer issues. When I contacted him to resolve the ticket, he started yelling and complained that this specific problem has reoccurred for the third time.

Without interrupting the user, I kept listening to him and when I got a chance, I ensured him that I understood his frustration and the effect that this problem is having on his productivity.

I also assured him that this time his problem would be resolved to his satisfaction and told him that his problem was my priority.

When the user calmed down, I started looking into the problem. It was an IP conflict issue that was disrupting the printer configuration periodically.


Question #9 – A user is finding it difficult to configure a printer on their computer. How can you help them?

After making sure that the printer is powered on, and the computer is connected to the printer, I will open the “Add Printer” wizard in Windows and select the required printer from the list of available printers.

I will use the ‘Add a Network, Wireless or Bluetooth’ printer option if we are operating in a networked environment.

I will also install and update printer drivers if necessary.

If the user’s computer normally fails to detect their network printer, I will enable ‘Network Discovery’ and ‘File and Printer Sharing’ options in the Network and Sharing Center in Control Panel.


Question #10 &#; How will you make sure that a system is not infected with a virus?

I will use a good anti-virus software to scan the computer for any viruses or malware.

I will also look for signs of virus-related problems, including unexplained slow speed, endless pop-ups and spam, functioning of .exe files, PUPs (Potentially Unwanted Programs), unfamiliar programs, and unintended events.


Question #11 &#; What is PTR (Pointer Record)?

A PTR record resolves an IP address to a full domain name.

PTR records are used to check a server’s association with the IP address from where the connection was initiated.

PTR is often known as Reverse DNS because a PTR associates an IP with a domain name, opposite to DNS which points domains to IP addresses.


Question #12 &#; What is a Logical Drive?

A Logical Drive is a virtual storage unit that exists on a physical hard drive but acts as an independent storage drive.


Question #13 &#; What is the purpose of a Logical Drive?

The purpose of a logical drive is to optimize storage performance by making contiguous storage units, allowing them to interact optimally without intervening with irrelevant or unrelated physical units.

Logical drives add abstraction in storage, making it easier for the operating system to read from memory.

Question #14 &#; How do you get the MAC address for a specific NIC?

We can use “getmac /v” in the command prompt dialog box, or we can also find it using the Ipconfig/all command.


Question #15 &#; How does a VPN work?

A VPN builds a private network over a public network with extra encryption to connect users to the private network’s resources.

A VPN masks the original IP address, identity, and location of the originator of a web request.


Question #16 &#; What happens behind the scenes when you type &#;; in the browser and hit enter?

When Enter is pressed, the browser checks the cache of the browser, operating system, router, and ISP for the DNS record to find the corresponding IP address of

If the IP address of Google is not found in these caches, the ISP’s DNS server will initiate a request to other DNS servers on the internet to find the IP address of

When my browser receives the appropriate IP address, it establishes a connection, usually a TCP connection.

Once the connection is established, the data transfer process will start.

The browser will send a GET request asking for the web page.

The server on the other end receives the request and the request handler (usually, a program written in common web languages like PHP, ASP, or RUBY) reads the request to identify what exactly is being requested and starts to assemble a response in the required format.

The server response contains the required web page and other details like compression type, cache format, cookie information, and more.

The browser will render HTML and send more GET requests, if necessary, based on HTML tags. Complete rendering will take place, which includes CSS, JavaScript files, images, and more.

The webpage will then appear on the browser.


Question #17 &#; What is the single most important factor that must be present in your work environment for you to be successful, and happily employed?

There could be several responses to this question. But here are the most useful ones that would convey to the interviewer that you plan to stick with the company, are willing to learn new things, and are open to challenges.

Your answer should be something like this:

The most important factor for me would be an opportunity to learn new things and the freedom to think outside of the box.

To be given a chance to present new ideas for growth and productivity.

To be appreciated when I work hard to remove obstacles in the way of the company’s goals and success.


Question #18 &#; How does a router work?

Routers manage the flow of data to multiple connected network devices.

If a packet has to go from Network A to Network D. The router connecting the Network A devices will first identify the best possible path for the packet to get to Network D, or the closest network to the final destination.  It does this by using a routing table to determine the best path based on the number of hops to the destination.

In simple words, a router sends IP packets to other networks using the best possible path which it identifies using routing tables.


Question #19 &#; You are asked by the company CEO to make sure that no employee in the company is able to open Facebook. How will you implement this policy?

There are several ways to do this, but the best one is to implement the restriction using the company’s router.

First, I will find the IP address of the main router by using the IPCONFIG command.

I will type the IP address in my browser to open the router’s settings. I will then open the content filter section.

I will add the Facebook URL to the content filter option.

This will block Facebook for all users.


Question #20 &#; What is a PST file and why is it important?

PST stands for personal storage table. A PST file is a file format built by Microsoft that is commonly used to store copies of emails, messages, calendar events, and other data items for applications like Microsoft Outlook.

The biggest advantage of a PST file is that it provides you with the portability to transfer your important Outlook data from one computer to the next.


Question #21 &#; A user complains that their computer clock resets every time they restart their PC. How would you solve this problem?

The most common cause of this problem is a faulty CMOS battery which provides power to Complementary Metal Oxide Semiconductor (CMOS) chip. This chip stores key information like data and time.

Replacing the CMOS battery solves this problem.


Question #22 &#; How you can you backup Outlook emails?

The best option is to use PST files to take Outlook backups.

We can use the Export option in Outlook to get a PST file for Outlook data.


Question #23 &#; What is DHCP?

DHCP stands for Dynamic Host Configuration Protocol. DHCP assigns unique IP addresses to hosts.

We use DHCP to automate the process of IP address assignments, so that we don’t have to manually assign IP addresses to computers or devices in large networks.


Question #24 &#; Ok. Can you tell me, in a bit more detail, how DHCP works?


A computer runs the DHCP client and sends a broadcast message requesting an IP address.

The DHCP server sends an IP address to the computer.

The computer accepts the IP address by sending a message back to the server.

The server sends an ACK message along with subnet mask, default gateway and other network details.


Question #25 &#; What is SCSI?

SCSI stands for Small Computer System Interface. It’s a type of fast, parallel bus that is used to connect several devices within the computer, including hard disks, scanners, CD-ROM, and tape drives.


Question #26 &#; What is the difference between incremental backup and differential backup?

A differential backup only copies those files that were changed since the last full backup. For example, if I take a differential backup of my files today, the backup will copy everything that was changed since the last full backup.

The full backup copies all data.

An incremental backup copies everything that changed since the last backup.  The last backup does not necessarily have to be a full backup.


Question #27 &#; You talked about DNS earlier in the interview. Can you explain what is DNS?

DNS translates domain names to IP addresses so that browsers can load internet and network resources for end users.


Question #28 &#; What is Reverse DNS Lookup and Forward DNS Lookup?

Forward DNS lookup converts domain names to IP addresses, while reverse DNS lookup converts IP addresses to domain names.


Question #29 &#; A user is unable to log in their computer even when they are typing their password correctly. How can you solve this problem?

After making sure that the user is entering the right username and password, I’ll check the network cables and connectivity to ensure that the user is connected to the network.

I will also check whether the user is added in the domain.

I can also use the “Manage User Account” option by signing in as an administrator to change the password of the problematic account and try signing in again.

Running a system file check using the SFC command also helps in fixing this problem.  Sometimes corrupt files hamper the sign-in process.

Starting the computer in Safe Mode and trying to sign in with a local account, and doing a system restore or a complete reset of Windows can also help to solve this problem.

Help desk interview questions with sample answers

Use these questions and example answers to help you prepare for your help desk interview:

  • Can you explain what a BIOS is?
  • Can you explain some of your past experience in technical support?
  • Can you explain the difference between RAM and ROM?
  • If a customer calls in saying the audio isn't working on their PC, how would you address the problem?
  • If a customer calls in saying their PC is slow, how would you address the problem?
  • If a customer calls in saying they experienced a blue screen, what would you do?
  • How long do you believe a phone call should last?
  • What type of problems have you worked with the most?
  • Can you describe a typical day in your previous help desk position?

Can you explain what BIOS is?

When working with software, some users may encounter issues requiring help desk employees to address other issues as well. Interviewers need to know that you understand and are capable of handling external issues caused by their programs, making BIOS a required topic. If possible, relate the specific term to how it is used within the role.

Example:"BIOS is an acronym that stands for Basic Input and Output System. Its firmware is used to support and troubleshoot hardware installation on a PC. There are occasions when proprietary software conflicts with the booting process of a PC, requiring me to walk callers through the BIOS screen and related processes. They report back to me what they see, and I provide a solution."

Can you explain some of your past experience in technical support?

This is a broad question, but your answer can provide more in-depth information on your background in the industry. If you have little experience, focus more on what you learned from the experience you have.

Example:"My most recent role was two years at a timeshare agency. All of our locations used the same systems and often had issues after deployments. I addressed the issues that arose, coming to the best solution I could. If we saw a high volume of the same issue, we reported them to our development team so they could send out fixes. Before that, I worked as a technical support agent for mobile phones."

Can you explain the difference between RAM and ROM?

This is a basic terminology question assessing your general PC knowledge. Some programs may affect hardware on the computer, so you should be familiar with them. Understanding the hardware allows you to better reach solutions for callers.

Example:"ROM is an acronym for Read-Only Memory. It's used to store the BIOS of a PC without needing additional power. Alternatively, RAM is an acronym for Random-Access Memory. It requires power and stores additional data that helps computers run faster and more efficiently."

If a customer calls in saying the audio isn't working on their PC, how would you address the problem?

Some help desk interview questions pose specific scenarios, testing how well you respond to them in the moment. The interviewer seeks an in-depth answer, including your thought processes or steps for addressing the issue.

Example:"Audio is a common problem when deploying new software. I often start by instructing the caller to reboot the computer, as it fixes most minor issues. If audio processes continue to fail, my next step is to confirm if the audio devices have been muted in settings or by any external mute buttons. I ask for confirmation that the speakers are turned on and the volume is at maximum. If it still refuses to work, I suggest plugging a set of headphones into the audio jack and test again. If that also fails, I focus my attention back to internal settings and confirm if the audio devices have check marks and are enabled. Beyond this, the issue may be a corrupted driver."

If a customer calls in saying their PC is slow, how would you address the problem?

This is another proposed scenario of a situation that is likely to occur. Proprietary applications can often slow down or cause the computer as a whole to slow down. Explain in detail your thought processes or steps for addressing this issue.

Example:"My first step would be to determine whether the slow down is related to our application or the computer itself. At my previous job, our programs had a feature that would repair the most recent update. It's a quick fix to many problems we experienced. If that doesn't work, I would run the application on a test computer to determine if I experienced the same slow down. If I do, then I know that it's most likely a software issue and I can tell the caller an update is coming. If I don't, then I can tell them it's related to their hardware and walk them through additional steps."

If a customer called in saying they experienced a blue screen, what would you do?

On rare occasions, updates cause computers to enter a blue screen mode with an error message. Similarly to the previous questions, explain the steps you would take and why you would take them in this situation.

Example:"The best way to address this initially is to ask the caller what the message said and if it provided an error code. Having an error code significantly speeds up this process, as I can quickly determine a cause. If they don't remember the message, I'd ask them to run the program again and repeat the same procedures. If it results in another blue screen, I know two things: It's probably related to the software, and I have an error code to work with."

How long do you believe a phone call should last?

While most help desk centers have their own metrics and standards, interviewers may want your opinion about phone call length. It gives them an idea of what you're used to as well as the standards you hold yourself to. Consider the call lengths imposed in previous positions and relate them to your personal customer service belief.

Example:"In my previous position, the maximum was seven minutes. I personally believe that no call should last longer than five minutes for most issues, and that is the standard I hold myself to. I'm usually able to determine the necessary length of the call once the caller describes their issue. In most cases, I know the proper fix immediately. There are always variables, of course, such as the caller giving misinformation by not knowing how to explain the issue."

What type of problems have you worked with the most?

Throughout the interview process, you may face questions that address your work history. This question in particular is a way for interviewers to get a better idea of what you're most experienced with. Consider your previous related roles and identify which problems you successfully addressed the most.

Example:"Most of the tickets we received at my previous job came shortly after deployments. Technical issues were almost always related to the new updates we sent out. Over time, I've memorized many of the standard procedures and can often identify the root cause of the problem early on."

Can you describe a typical day in your previous help desk position?

A question like this helps identify what your previous experience involved. Interviewers use this to compare it to the experience you might have with them. In most cases, this is a simple question to answer. Be honest and transparent about your daily activities.

Example:"At my previous job, the day started first by finding an open cubicle. I'd log into all of my necessary programs, pack away my bag and enter the caller queue. I handled calls up to around noon, barring any breaks I may take, depending on call volume. This type of day only changes if I worked weekends or nights. Call volumes were generally lower then, giving us free time to look up common issues and prepare for upcoming phone calls."

Help Desk Interview Questions and Tips for Answering

If you're interviewing for a help desk role, it's helpful to have a sense of what to expect. That way, you can practice your responses to common help desk interview questions, so you'll feel poised and confident expressing yourself during the actual interview.

What Employers Want to Know

During a help desk interview, candidates are primarily evaluated based on their technical know-how, problem-solving abilities, and communication skills. Also, since help desk specialists get a wide variety of questions through email, chat programs, and the phone, interviewers will be looking for people who are flexible and prepared to take on a wide range of issues. A strong help desk employee is just as comfortable answering questions over the phone as in a chat program. 

Finally, since help desk problems, questions, and requests from customers may range in tone from polite to rude and from calm to anxious, interviewers will be eager for candidates who are unflappable and can maintain their cool even during stressful situations. Therefore, expect interview questions that address (and even test) some of these important customer service skills.

Types of Interview Questions

Interviewers will ask various types of questions to learn whether or not you have the skills and experience for the job. Some will be common interview questions you might be asked for any job, including questions about your work history, your strengths and weaknesses, and your skills. Others will be personal questions about your qualities as they relate to the job. For example, you might be asked how you handle pressure, why you want to work at a help desk, and more.

Be prepared to be asked technical questions similar to the “trouble tickets” you might be asked to resolve on the job. 

You will also likely be asked a number of behavioral interview questions. These are questions about how you’ve handled certain work situations in the past. Other questions will probably be situational interview questions. These are similar to behavioral interview questions, but they involve future situations rather than past experiences.

Tips for Preparing

When answering questions during your interview for a help desk position, it can be helpful to give examples of how you have managed similar situations in past jobs. For instance, if you are asked how you would handle callers who can't convey their technical issues, you can relate a story of how you dealt with a similar problem. These references to the past can help solidify your experience to an interviewer.

When answering a question using a specific example, use the STAR interview technique. Describe the situation you were in, explain the task you had to accomplish, and detail the action you took to accomplish that task (or solve that problem). Then, describe the results of your actions.

Common Help Desk Interview Questions

Practice answering these common help desk interview questions. When possible, give examples from your on-the-job experience. 

Personal Questions

  • What does excellent customer service mean to you? Best answers
  • What is your biggest strength? What is your biggest weakness? Best answers
  • What do you find most rewarding about working at a help desk?

Tips for responding: It can be helpful to highlight that you enjoy helping people or solving problems. Avoid answers that might seem selfish or unprofessional, such as enjoying the long periods of downtime. 

IT Questions

  • In which IT areas do you consider yourself to be an expert? Best answers

Tips for responding: Be strategic! If you know the company's help desk gets a lot of questions around one area, make sure to include that in your response. 

  • How do you keep your IT knowledge and skills current?

Tips for responding: You can talk about online resources or social media accounts you follow, as well as any classes you have taken (or plan to take). 

  • What is ITIL? How can you apply ITIL to your position at a help desk?
  • What programs have you used to log and date calls?

Tips for responding: List out specific programs. It can be helpful, as well, to emphasize your willingness and ability to pick up new software technologies easily. 

Behavioral Questions

  • Tell me about a time when it was particularly difficult for a caller to explain a problem to you. How did you reach an understanding of the issue?

Tips for responding: Using the STAR technique can help you provide a succinct response.  

  • Give me an example of a time when you had to simplify complex information to explain it to a caller.
  • Tell me about a time when you had to deal with a particularly hostile customer or caller. How did you handle the issue? Is there anything you would have done differently?

Tips for responding: Don't try to dodge the question by saying you've never dealt with a difficult customer. That'll seem disingenuous. Instead, focus on how you formed a connection or overcame hostility by solving the problem or explaining it. 

  • Tell me about a problem you had to solve that tested your analytical abilities. What resources did you use?
  • How have you responded in the past when you received negative feedback from a customer or caller about you personally?

Situational Questions

  • Imagine someone calls with a technical issue with which you are completely unfamiliar. How would you handle the situation? 
  • Imagine a caller has trouble understanding what you are trying to explain to him. What do you do to help him understand you?
  • If a customer calls saying his computer won't boot, how will you troubleshoot it? 
  • If someone finds that their Internet connectivity is down, how will you fix the problem?

In addition to job-specific interview questions, you will also be asked more general questions about your employment history, education, strengths, weaknesses, achievements, goals, and plans. Take the time to formulate and rehearse your answers to these questions. This will give you an added boost of self-confidence during the interview itself.

Key Takeaways

SHOWCASE YOUR TECH SKILLS: Be prepared to demonstrate your competency both in standard help desk communications tools and, if relevant, in the employer’s tech products.

CUSTOMER SERVICE COUNTS: Think of past experiences you’ve had in handling difficult customers. What strategies did you use to communicate with them and resolve their issues?

BE A STAR: Use the STAR interview response technique to describe a situation where you provided stellar service within a help desk capacity.
