Describe a time you improved a process. (Behavioural)
What they're looking for: Initiative.
STAR outline: S: Slow laptop setup. T: Improve. A: Moved to Intune Autopilot. R: Setup time dropped from half a day to under two hours.
How do you document a ticket? (Technical)
What they're looking for: Good documentation habits.
Strong answer covers: Record the user's description and impact, steps taken and results, the root cause if known, the resolution, time spent and any follow-up — written so another analyst could pick it up. Turn repeat fixes into knowledge-base articles.
You can't solve an issue. What do you do? (Situational)
What they're looking for: Knowing when to escalate.
STAR outline: Set a timebox, check the knowledge base and colleagues, document what you've tried, update the user on next steps, and escalate to Tier 2 or the right team with clear notes so they don't repeat your steps.
Tell me about handling a frustrated user. (Behavioural)
What they're looking for: Patience.
STAR outline: S: A user lost access to files minutes before a client meeting. T: Calm them and restore access.

What's DNS and why does it matter? (Technical)
What they're looking for: Networking basics.
Strong answer covers: DNS translates names (like a website or server name) into IP addresses. If DNS fails or is misconfigured, users can't reach sites or internal services even when the network is up; checks include nslookup, flushing the cache and confirming DNS server settings.
Why IT support? (Behavioural)
What they're looking for: Motivation.
STAR outline: Explain that you enjoy solving problems and helping people work smoothly, mention a project or home lab that shows your interest, and share goals such as Network+, Microsoft or security certifications.
