Why they ask this: They want to see how well you know yourself and whether you can speak honestly about your experiences and goals.
Sample Answer:
“I’d say one of my biggest strengths is staying calm and focused, even when things get hectic or high-pressure—it helps me think clearly and keep things moving in the right direction. It helps me think clearly, make good decisions, and support others when things get hectic. I’ve had users yelling over printers or crashing systems five minutes before a big meeting, and I’ve always stayed composed and resolved the issues quickly. I’m also a fast learner and regularly take online courses to improve my knowledge.
As for weaknesses, I used to struggle with saying ‘no’ and overcommitting to helping too many users at once, which affected my response time. I’ve since learned to manage expectations better and prioritize tasks effectively.”
Tip: Avoid turning a strength into a fake weakness—it can come off as insincere. Keep it real about your weaknesses, but also share how you’re working to improve them.
4. How do you prioritize multiple support requests?
Why it’s asked: To evaluate your organizational and time-management skills.
Sample Answer:
“I prioritize tasks based on impact and urgency. If a senior executive can’t log in or a department-wide issue like internet failure occurs, that takes top priority. For less critical issues like minor software glitches, I log them and address them based on the queue order. I use ticketing systems like Zendesk and ServiceNow to keep track of requests and update users on ETAs. Communication is key—I always keep users informed about delays or changes in the priority of their issues.”

5. Describe a situation where you handled a difficult user or a stressful support scenario.
Why it’s asked: To assess your interpersonal skills and emotional intelligence.
Sample Answer:
“Once, a user was extremely upset because their report disappeared moments before a board presentation. They were blaming the system and the IT team. I calmly reassured them I would help and asked if they had saved or emailed a copy. While speaking, I checked the temporary files and recovered an autosaved version in Word. They were relieved and thanked me afterward.
I’ve learned that staying calm, listening without interrupting, and showing empathy goes a long way in diffusing tension. Even when it’s not a tech issue, how you handle people matters just as much.”
Tip: Choose a real-life example. Show empathy, problem-solving, and communication skills.
6. How would you troubleshoot a computer that won’t turn on?
Why it’s asked: To assess your hardware troubleshooting process and logical thinking.
Sample Answer:
“When my computer won’t turn on, the first thing I do is double-check the power source—making sure the outlet or power strip is working.I then verify that the power cableis securely plugged into both the PC and the wall socket. If there’s still no response, I try using a different power cable to rule out a faulty wire.
Next, I check for signs of life—any LED lights, fan activity, or beeps. If there are beep codes, I refer to the motherboard’s manual to diagnose the issue. I may also try reseating the RAM, checking the PSU, or testing with a known working power supply.
If it’s a laptop, I’d try removing the battery (if I can) and then plug it straight into the AC power to see if that works.Once I isolate the problem, I either replace the faulty component or escalate to the hardware team if needed.”
Tip: Walk through your diagnosis logically. Mention tools (like PSU testers) or troubleshooting steps you’ve used in real-life scenarios.
7. How do you handle a slow-performing computer?
Why it’s asked: To evaluate your OS knowledge, diagnostic skills, and efficiency.
Sample Answer:
“I begin by asking the user when they noticed the slowness and if it’s consistent or intermittent. Then, I use Task Manager to check CPU, memory, and disk usage. If a process is hogging resources, I investigate further—like updating or disabling background apps, browser extensions, or startup items.
I check the disk space, run Disk Cleanup, defragment (for HDDs), or scan for malware using Windows Defender or third-party tools. If performance is still slow, I run CHKDSK to check for disk errors, update drivers, and check Event Viewer for hardware warnings.
Sometimes, outdated or bloated antivirus programs slow down performance, so I assess their configuration. In some cases, adding RAM or upgrading to an SSD might be necessary. I always document what changes I make for future tracking.”
Tip: Use real troubleshooting tools in your answer. Show that you don’t jump to conclusions—you follow a process.
8. What is Active Directory, and how do you use it in support?
Why it’s asked: To confirm your experience with user account management and directory services.
Sample Answer:
Active Directory (AD) is a Microsoft tool that helps organize and manage users, computers, and other resources on a network.In my role in desktop support, I frequently work with AD to reset passwords, unlock user accounts, move users between organizational units (OUs), and assign them to appropriate security groups.
For example, when a user can’t log in, I check if the account is locked or disabled. If they’ve forgotten their password, I reset it and ensure it complies with our policy. I’ve also used AD to apply group policies (GPOs), such as enforcing screensaver lock after inactivity or restricting access to control panels.
Using ADUC (Active Directory Users and Computers), I ensure that user permissions align with their job roles and that access is removed immediately for terminated accounts.”
Tip: Mention common tasks you perform in AD. Highlight both security and usability aspects.
9. What would you do if a user couldn’t connect to the internet?
Why it’s asked: To check your network troubleshooting skills and attention to detail.
Sample Answer:
“I’d start by asking if it’s just one user or if others are affected. If it’s isolated, I’d check the physical connection—verify the Ethernet cable or test the Wi-Fi signal. Then, I’d run basic commands like ipconfig /all to see if the device has a valid IP address and DNS settings.
If the IP address is missing or wrong, I typically run “ipconfig /release” followed by “ipconfig /renew” to get a new one.I’d also ping the gateway and a public IP (like 8.8.8.8) to identify if it’s a local or broader issue. If DNS is the issue, I’d switch to a public DNS server temporarily to see if that resolves the problem.
If hardware and IP settings check out, I’d investigate proxy settings, firewall configurations, or software conflicts like VPNs. Documentation and clear communication with users throughout are crucial.”
Tip: Highlight methodical problem-solving and make sure you reference tools like CMD or IP settings.
10. How do you manage software installation and updates?
Why it’s asked: To confirm you follow organizational policies and understand software deployment.
Sample Answer:
“I always ensure software installations are approved and licensed before proceeding. For manual installs, I log in with administrator credentials and install only from trusted sources.I turn off automatic updates when the company policy requires all patches to be managed centrally.
In enterprise environments, I’ve used tools like Microsoft Endpoint Manager (SCCM) or PDQ Deploy for software pushes and patch management. These tools help automate deployments, enforce version compliance, and track software usage.
I also ensure that installation doesn’t interfere with existing configurations. After installation, I test functionality, add shortcuts if needed, and document the install for asset management. For updates, I coordinate with the IT team and schedule them during off-peak hours to minimize downtime.”
Tip: Emphasize safe practices and automation tools you’ve used. Mention licensing, security, and rollback plans.
11. Can you think of a time when you had to troubleshoot something quickly, under pressure?
Why it’s asked: To assess how well you handle high-stress situations without losing effectiveness.
Sample Answer:
“During one of my previous roles, our CEO was about to present at a major virtual conference when their laptop crashed and wouldn’t boot. It was 15 minutes before the event. I immediately brought a backup laptop I had pre-configured for such emergencies. While they logged in, I retrieved their presentation from our shared OneDrive and preloaded it.
Afterward, I diagnosed the issue—it turned out to be a corrupt Windows update. I restored the laptop using a system restore point and ensured it was fully updated and operational within the day.
That situation taught me the importance of having contingency plans and being able to keep calm under pressure. Because of that incident, we later implemented standardized backup laptops for all top executives.”
Tip: Use the STAR method (Situation, Task, Action, Result) for behavioral answers. Focus on your calm demeanor and resourcefulness.
12. How do you handle users who aren’t tech-savvy or are upset?
Why it’s asked: To evaluate your communication, patience, and empathy.
Sample Answer:
“I’ve found that showing empathy really makes a difference in IT support. When users are frustrated, I let them explain their issue without interruption. I let them know I understand their frustration and assure them I’ll fix the issue as quickly as I can.
For non-tech-savvy users, I avoid jargon. Instead of saying, ‘Let me check your DNS settings,’ I say, ‘Let me see why your computer isn’t connecting to the internet.’ I walk them through what I’m doing, which builds trust.
One example: A user lost access to their files and was panicking before a meeting. I stayed calm, recovered their data from a synced backup, and explained how they could avoid the issue in the future. They were not only relieved but appreciative of the clarity and patience.”
Tip: Showcase your ability to empathize and adapt your language depending on the user’s technical understanding.
13. What remote support tools have you used?
Why it’s asked: To assess your familiarity with remote assistance, especially in hybrid or remote teams.
Sample Answer:
“I’ve used a variety of remote support tools including TeamViewer, AnyDesk, Microsoft Remote Desktop, LogMeIn, and ConnectWise. In my last role, we relied heavily on TeamViewer for cross-location support. I used it to install software, run scripts, troubleshoot hardware peripherals, and configure Outlook settings remotely.
For enterprise environments, I’ve worked with Microsoft Endpoint Configuration Manager and Remote Assistance built into Windows. I’m always cautious with permissions, ensuring proper authentication and getting user approval before initiating sessions. I also document remote sessions to ensure compliance with IT policies.”
Tip: Emphasize remote troubleshooting etiquette—security, communication, and transparency.
14. What antivirus and security protocols are you familiar with?
Why it’s asked: To ensure you understand the basics of endpoint security.
Sample Answer:
“I’ve worked with antivirus solutions like Symantec Endpoint Protection, Windows Defender, McAfee, and Bitdefender. I ensure regular signature updates are enabled and perform periodic scans to catch threats early.
Beyond antivirus, I follow security protocols such as enforcing strong password policies, enabling BitLocker for drive encryption, limiting admin access, and ensuring devices are patched regularly. I also educate users on phishing threats and check if systems are compliant with our security baselines.
In one case, a user downloaded a suspicious file.I disconnected the device from the network, ran a full scan, and notified the cybersecurity team about the incident.We used the event logs to trace the origin and confirmed no data was exfiltrated.”
Tip: Show you’re proactive about security and not just reliant on antivirus tools. Mention response and prevention strategies.
15. Where do you see yourself in the next 3 to 5 years?
Why it’s asked: To understand your career goals and whether you plan to grow within the company.
Sample Answer:
“In 3–5 years, I hope to evolve into a systems administrator or network engineer role. I see desktop support as a foundational part of IT, where I can learn how infrastructure, users, and software interact. That experience will help me transition into more advanced roles.
I’m currently studying for my CompTIA Network+ and plan to follow up with Microsoft and Cisco certifications.I really enjoy mentoring newer techs and hope to take on more leadership roles down the line.
What excites me about this company is the potential to grow from within, so I’m looking for a long-term fit.”
Tip: Align your goals with the company’s internal growth paths. Show ambition but grounded in experience.
