Tell me about a time when someone pointed out something you did wrong. How did you feel about it? What was the situation? What did you say?
Sometimes it can be difficult to be corrected at work, but it's also a part of learning and growing in your field. Try to think of a specific example that happened where you made a small mistake that made a small impact. It is ok to admit that you made a mistake, as it happens to everyone. The interviewer is looking to see how you handled the correction and what you did as a result.
"When I was an apprentice, I made a fair amount of small mistakes during the process of learning my trade. Once, I went into a boiler without first making sure it was clear because I saw my supervisor go in earlier. He saw me do this and immediately corrected me, saying that I can't assume it's still safe to enter just because it was safe earlier. That stuck with me; now, I don't make any assumptions. I always ask myself if I'm making an assumption about something or if I have evidence to support what I'm doing."
