Tell me about a mistake you made at work. What did you learn from it?
Why interviewers ask this
Everyone makes mistakes. The interviewer wants to see whether you take ownership, fix problems quickly and learn from them — or whether you hide errors and blame others.
Your answer also shows honesty and judgment: choosing a real, meaningful mistake and talking about it calmly is a sign of maturity. Interviewers often trust candidates more after this question, because an honest story about getting something wrong makes their other answers more credible.
How to answer
- Choose a genuine mistake with real consequences, but not one that caused serious harm or questions your integrity.
- Take clear ownership — say “I” and avoid shifting the blame.
- Explain what you did to fix it, quickly and specifically.
- Spend a good part of the answer on what you learned and the habit or process you changed.
- If possible, show that the lesson has worked since then.
Example answers
Early in my recruiting career, I sent a job offer to a candidate with the wrong salary figure — I’d copied a template from a different role and didn’t check it carefully. The candidate accepted, and the hiring manager spotted the error the next day. I called the candidate straight away, apologized, explained the mistake honestly and confirmed the correct figure, which was slightly lower. I was worried we’d lose her, but because I was upfront she appreciated it and still joined. Since then, I never reuse old offer letters; I generate every offer from the approved details and ask a colleague to double-check figures before anything goes out. I haven’t had an error on an offer since.
A couple of years ago I approved a large seasonal stock order based on the previous year’s sales without checking that a new competitor had opened nearby. We ended the season with a lot of unsold stock, which we had to discount heavily. I reported it to my area manager myself, with a plan to clear the stock through promotions and transfers to other stores. The lesson was that historical data isn’t enough on its own. Now, before any big order, I look at what’s changed locally and talk to my team, who often notice changes in footfall first. My orders have been much closer to actual sales since.
Mistakes to avoid
- Saying you have never made a mistake at work.
- Choosing a tiny, trivial error that shows nothing about how you handle real problems.
- Blaming other people or circumstances for what went wrong.
- Describing a mistake without any lesson or change in behavior.
