Which was one of the biggest mistakes you have committed in your past projects? How has it impacted your approach to work?

To err is human, they say. It is how you deal with the errors that define your skills. By asking this project management interview question, the interviewer intends to check your honesty and whether you take the responsibility of mistakes you have made in your past projects. Rather than giving a ‘no’ for the answer, you can mention a couple of mistakes. Make sure you show that you take responsibility for the mistake as it is a way to reveal your maturity level. Also, you can explain how you had resolved it.
