"Tell us about a time you made a mistake": how to answer

What recruiters look for

• Honesty. You own your part rather than blaming other people or the situation.
• Putting it right. You acted quickly to fix the problem or limit the damage.
• Learning. You can name what you changed afterwards, and show you've used it since.
• Judgement. The mistake is real, but not one that raises doubts about you for the role.

The Civil Service's guidance on behaviours says less successful examples "can be used if you can demonstrate the lessons learned and how errors would be avoided in future" (checked 25 October 2026). The Civil Service isn't connected with Aplara and doesn't endorse it.

Choosing the right mistake

Good examples: missing a deadline because you underestimated a task, a calculation error in coursework you caught late, a misunderstanding with a teammate or customer, or taking on too much at once. Avoid anything illegal, dishonest or dangerous, and anything you'd find hard to talk about at interview.

A structure to follow

1. The mistake: what you did, owned in one or two sentences.
2. The impact: who or what it affected.
3. Putting it right: what you did straight away.
4. What changed: the habit you changed, and a time you've used it since.

Example answer

Sam is a fictional second-year mechanical engineering student. The details are invented to show the shape of a good answer. Use your own.

During my summer job in a café, I took a large phone order for a children's party and wrote down the wrong collection day, so the customer arrived to find nothing ready. I apologised, told my manager straight away and offered to stay late so we could make a smaller order within the hour, which the customer accepted. The mistake was mine: I'd taken the order while serving at the counter and hadn't read it back. Since then I repeat key details back to the person and write them down before I move on. I used the same habit on my university group project, confirming deadlines in our group chat after every meeting, and we didn't miss one.

Common mistakes

• A fake mistake. "I work too hard" or "I care too much" reads as dodging the question.
• Blaming others. If a teammate or manager was at fault, it isn't your mistake.
• Too long on the mistake. Keep it short; the recovery and the learning matter most.
• No proof you changed. Saying you learned something is weaker than showing a time you used it.
• A generic AI answer. "I learned the importance of attention to detail" without a specific change says nothing.
