A useful starting point
Build your answer with STAR.
Choose one real event you can discuss in detail. Work, education, volunteering and everyday responsibilities can all give you useful examples.
Situation
Where were you, and what was happening? Keep the background brief.
Task
What were you personally responsible for? What needed to happen?
Action
What did you do, in what order, and why? Give your own actions the most attention.
Result
What happened? Explain what you learned and what you would do again or improve.

The same example, step by step
Situation
At the end of a long shift at my previous job, I was securing equipment in the yard and inadvertently left one machine's safety guard unfastened. I was halfway to the car park when I realised what I had done.
Task
I needed to correct my mistake immediately and report it transparently, even though no one else had noticed and I was tired and eager to go home.
Action
I contacted my supervisor immediately and explained which guard I had left unfastened. I followed the approved arrangements to prevent the equipment being used and to have it made safe. I recorded the mistake before leaving and suggested a clearer final check for the supervisor to review, rather than changing the procedure myself.
Result
The equipment was checked and made safe before being used again. My supervisor reviewed the closing checklist and explained the agreed change to the team. I learned that reporting an error immediately is more useful than trying to hide it or waiting until the next shift.
Before you move on
Review your answer.
- Be honest about the mistake (they'll likely know)
- Focus on taking responsibility immediately
- Explain what you learned from the experience
- Show how you prevented similar mistakes
