1. Tell me about yourself.
What they are testing: Communication skills + relevance to the role.
✅ Winning Answer:
“I am an IT support professional with experience troubleshooting hardware, software, and user-access issues while providing excellent customer service. My background includes supporting users with system setup, password resets, application errors, and network connectivity problems.
I enjoy diagnosing technical problems and translating technical language into simple explanations for users. In my previous role, I improved ticket resolution time by prioritising incidents effectively and documenting solutions for future reference. I’m now looking to contribute my technical and customer-focused skills in a structured IT support environment.”
2. What does good technical support mean to you?
What they want: Customer-first mindset.
✅ Winning Answer:
“Good technical support means resolving issues efficiently while ensuring the user feels supported and informed. It involves active listening, accurate diagnosis, clear communication, and preventing repeat issues through documentation or education.
Technical skills solve the problem, but communication builds trust.”
3. How do you troubleshoot a technical issue?
They want: Structured thinking.
✅ Winning Answer (Use a framework):
“I follow a structured troubleshooting process:
- Identify the problem by asking questions.
- Replicate or observe the issue.
- Check simple causes first.
- Isolate whether it’s hardware, software, or network-related.
- Apply a solution or workaround.
- Test the fix.
- Document the resolution.
This approach ensures consistency and reduces resolution time.”
4. A user says their computer is slow. What would you do?
✅ Winning Answer:
“I would first ask when the issue started and what applications are running. Then I would:
- Check CPU and memory usage via Task Manager
- Close unnecessary programs
- Check startup applications
- Scan for malware
- Verify disk space
- Check for pending updates
If needed, I would escalate hardware upgrade recommendations or deeper system diagnostics.”
5. How do you handle difficult or frustrated users?
Very important question.
✅ Winning Answer:
“I remain calm and empathetic. I allow the user to explain the issue fully without interruption, acknowledge their frustration, and reassure them I will help resolve it.
I avoid technical jargon and keep them updated during troubleshooting. Often, users calm down once they feel heard and informed.”
6. What is the difference between hardware and software issues?
✅ Winning Answer:
“Hardware issues relate to physical components such as hard drives, RAM, keyboards, or monitors. Software issues involve operating systems, applications, or configuration errors.
For example:
- A failing hard drive is hardware.
- An application crash is software.”
7. What would you do if you cannot solve a problem?
✅ Winning Answer:
“If I cannot resolve an issue after reasonable troubleshooting:
- I document all steps already taken.
- Research internal knowledge bases.
- Consult colleagues if appropriate.
- Escalate to the next support level with detailed notes.
This prevents duplication and speeds resolution.”
8. Explain DNS in simple terms.
They test communication ability.
✅ Winning Answer:
“DNS works like the internet’s phonebook. Instead of remembering IP addresses, users type a website name, and DNS translates that name into the correct IP address so the computer can locate the server.”
9. What is Active Directory?
✅ Winning Answer:
“Active Directory is a Microsoft directory service used to manage users, computers, permissions, and security within a network. It allows administrators to control access centrally, manage login credentials, and apply policies across devices.”
10. How do you prioritise support tickets?
✅ Winning Answer:
“I prioritise based on impact and urgency:
- Critical: System outages affecting many users.
- High: Business-critical user unable to work.
- Medium: Partial functionality issues.
- Low: General requests or minor problems.
I follow SLA guidelines while keeping users informed.”
11. Describe a time you solved a technical problem.
✅ Winning STAR Answer:
Situation: A user couldn’t access a critical application.
Task: Restore access quickly.
Action: I checked permissions, verified network access, and discovered their account was locked due to failed login attempts. I unlocked the account and reset credentials securely.
Result: Access restored within 10 minutes, preventing workflow delays.
12. What operating systems are you familiar with?
✅ Winning Answer:
“I have experience supporting Windows environments, including user account management, system updates, troubleshooting software issues, and basic networking configurations. I’m also familiar with macOS basics and continually improve my knowledge through hands-on practice.”
(Adjust based on your experience.)
13. How do you stay updated with new technology?
✅ Winning Answer:
“I regularly follow IT learning platforms, technical forums, and vendor documentation. I also practice in home lab environments and take online courses to strengthen skills in areas like networking, cloud services, and troubleshooting.”
14. What would you check if a user cannot connect to the internet?
✅ Winning Answer:
“I would check systematically:
- Physical connections or Wi-Fi status
- IP configuration (ipconfig)
- Network adapter status
- Router/network availability
- DNS resolution
- Test another device
This helps isolate whether the issue is device-specific or network-wide.”
15. Why should we hire you for this IT support role?
