Think about a mistake that you made that is significant enough to mention, but not so damaging that you wouldn’t be hired. Employers hear “I don’t make mistakes” all the time and know that this is not true. It is better to be honest and put a positive spin on how you learned not to repeat the same mistake twice.
•“I always double check my work to avoid making mistakes and almost always catch a mistake before it becomes critical. However, one time, I forgot to XYZ. I have learned to set my work aside for a few minutes and look it over again with fresh eyes.”
•“At the beginning of my career, I had a hard time asking for help. When my manager gave me too many projects at once, I didn’t say anything and was unable to complete one project by my deadline. I have since learned to communicate the status of my projects and prioritize with my supervisor not to miss a deadline.”
