Everybody would love to have a' do over' at some point in their life. This applies to their professional life as well. We've all made a decision that, in hindsight, we either regret or would like to take in a different direction. Interviewers understand this and may ask you about it. One reason is to test your honesty and your ability to accurately evaluate your actions. The other is to determine the scope of the decision you would like to change, and how much it impacted the organization you are working for. When responding to this question, describe a situation that had a minor impact and would be beneficial to the organization if corrected.
