Preparing for this question requires a little bit of self-awareness and strategy. You don't want to share that you have trouble working with difficult people or that you struggle with the details, as those are key aspects of your role. What you do want to focus on is a weakness that you could possibly turn into a strength. You want to share something that would not be detrimental to your role that you are working on improving. Being a people-pleaser or a perfectionist are great examples of weaknesses that could be turned into strengths. This example below goes from talking about a weakness to showing how it has helped create awareness and an ability to set boundaries. Always share what you are learning or have learned from your weakness. This shows your interviewer that you are adaptable and willing to grow.
