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.

Questions asked across Technology & IT
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.
An AI assistant gives you code or configuration that runs but that you don't fully understand. What do you do?2026
The only safe answer: you don't ship what you can't explain. Describe how you'd read, test and simplify it until you own it.
How does security show up in your day-to-day work, whatever your role?
Concrete habits beat buzzwords: least privilege, secrets handling, dependency updates, questioning odd requests.
Tell me about a time you disagreed with a technical approach chosen by someone more senior.
Show respectful challenge with evidence, then commitment once decided. Either outcome can be a good story if you learned from it.
