The questions to expect
Tell me about a time you helped a frustrated user. How did you keep them calm?
Empathy first, jargon never: acknowledge, set expectations, follow up. The result is the user's trust, not just the fixed laptop.
Describe a fault that took you a long time to diagnose. What was your process?
Show a method — reproduce, isolate variables, check what changed recently — and when you decided to escalate rather than struggle on.
Several urgent tickets land at once. How do you decide what to fix first?
Impact and urgency, honestly triaged: how many people blocked, is there a workaround, who needs an update while they wait.
A user can't log in and they're presenting to a client in ten minutes. Talk me through exactly what you do.
Fast workaround before deep fix: get them presenting (spare account, another machine), reassure them, then solve the root cause after.
A PC boots fine but has no network connection. Walk me through your troubleshooting steps.
Work in order — cable/Wi-Fi, adapter, IP config (ipconfig), ping gateway, DNS — and say what each step rules out.
What's the difference between 1st and 2nd line support, and how do you decide when to escalate?
Show you escalate on impact and time-box, not ego — and that you pass tickets up with clean notes so no one repeats your steps.
How would you talk a non-technical user through a fix over the phone?
Small steps, confirm each one, describe what they should see. Patience is the skill being tested — let it show.
Why IT support? What do you enjoy about the work?
The honest good answer combines liking people and liking puzzles — and a line about where you want the role to take you.
Users now ask AI chatbots before they ever call the service desk. How does that change first-line support?2026
Sharp answer: easy tickets shrink, weird half-fixed ones grow. Show you verify what the user already tried and use AI tools yourself, carefully.
Tell me about a time you explained a technical problem to someone non-technical.
Pick a real audience and show the translation: the analogy you used, what you left out, and how you checked they got it.
Describe a production incident you were involved in. What did you do first?
Order matters: mitigate, communicate, then root-cause. Finish with the fix that stopped it happening again.
Walk me through a technical decision you made that you later reversed.
Reversing well is the skill. Show what new information arrived, how fast you acted on it, and what the reversal cost.
How to prepare for a it support technician interview in the UK
UK service desk interviews are heavily customer-service weighted — expect at least as many people questions as technical ones. Mentioning ITIL basics (incident vs request, SLAs) lands well even for 1st line roles.
How Technology & IT interviews are run in 2026
- Coding rounds increasingly allow — or expect — an AI assistant: you are marked on how you prompt, verify and fix its output, not typing speed. Live reasoning, debugging and code-review rounds have grown to compensate.
- System design and 'explain your thinking out loud' rounds carry more weight than puzzle-style coding; many employers explicitly verify real-time reasoning because take-homes are now AI-solvable.
- Volume employers screen with async one-way video and online tests before any human round, so camera practice matters at the top of the funnel.
