IT Support Specialist interview questions
IT support interviews test your troubleshooting method and how you treat frustrated users. Being patient counts as much as technical knowledge.
What interviewers look for
- Troubleshooting. A logical order of checks.
- Fundamentals. Windows, networking and accounts.
- Service. Clear communication with non-technical people.
How the interview usually runs
- Phone screen.
- Technical interview.
- Practical troubleshooting scenario.
- Meeting with the team.
Stages vary by company, so ask the recruiter what to expect before you start preparing.

A sample answer
A user can't get online. What do you check?
I'd first ask whether others are affected, to see if it's just them. Then I'd check Wi-Fi or the cable, and run ipconfig. If there's no valid IP, I'd look at DHCP or the switch port. If the IP is fine, I'd ping the gateway, then test DNS. I'd update the ticket and tell the user what I found.
A made-up example to show the structure. Use your own experience and real numbers.Common mistakes
- Jumping to reinstalling Windows.
- Forgetting to ask if it's only one user.
- Using jargon with users.
- Skipping identity checks on resets.
