STAR method: how to answer behavioural interview questions (with examples)
4 min read · Updated 21 October 2026
Questions that start with “Tell me about a time when…” are behavioural questions. The interviewer wants to hear what you actually did, not what you would do in theory. The STAR structure keeps your answer short, clear and easy to follow.
What STAR stands for
- Situation: the context, in one or two sentences.
- Task: what you were responsible for.
- Action: what you did, step by step. This should be the longest part.
- Result: what happened, with a number if you have one, and what you learned.
Example: “Tell me about a time you worked to a tight deadline”
Situation: two days before a client demo, we found our report export was timing out on large accounts. Task: I owned the export feature, so fixing it before the demo was on me. Action: I profiled the query, found it was loading every row into memory, and changed it to stream the results in batches. I tested it against a copy of the largest account and kept the team updated twice a day. Result: the export finished in under a minute instead of timing out, the demo went ahead on time, and we added a large-account test to our release checklist.
Example: “Tell me about a time you disagreed with a teammate”
Situation: a teammate wanted to add a new library to handle dates across our app. Task: I thought it added risk for a small gain, and we needed to decide before the sprint started. Action: instead of arguing in the meeting, I wrote a short comparison of both options, covering bundle size, the bugs we'd actually had, and migration effort, and we reviewed it together. Result: we agreed to use the library only in the one module that needed it. The rest of the app stayed unchanged, and we now use the same written-comparison approach for other tech decisions.
Mistakes that weaken STAR answers
- Spending most of the time on the Situation. Keep it to a couple of sentences.
- Saying “we” all the way through. The interviewer is hiring you, so say what you did.
- No result, or a vague one. If you have no number, describe the outcome and what changed.
- Choosing a story where you made no decisions. Pick one where your actions mattered.
Prepare once, use many times
Prepare five or six stories: a success, a failure, a conflict, a tight deadline, a time you led something, and a time you learned something fast. Most behavioural questions can be answered with one of them, slightly reshaped.
