Are you aware of your weaknesses? Interviewers understand that we have weaknesses, and they want to hear that you understand yourself. Think of an area of your life that you are proactively working to improve, and openly share it. Perhaps your weakness is that you get nervous speaking in front of large groups of people. The key to this question is ensuring that you acknowledge your weakness and that you are taking steps to grow in this area. It shows the interviewer that you have initiative. Think about ways you have stretched yourself to grow in your area of weakness. Did you sign up to speak at a conference to give yourself the opportunity to develop your public speaking skills? Tell the interviewewr what you are doing to improve and grow.
