We all have things we can improve on, so do not be afraid to share them. The interviewer will likely take note of your greatest weakness and may even provide you with additional training or mentoring if possible to help you excel. The interviewer wants to hear that your weakness is not critical for the job you are applying to. Think of something you could improve upon that is not necessary for the job, and openly share it with the interviewer. Next, share what things you have done to improve upon your weakness. The key is to have a plan! The interviewer wants to hear that you work through your weaknesses and do not allow them to be stumbling blocks. Simply share 1-2 ways you have worked on your weakness. This might including doing something to push yourself outside of your comfort zone, attending a seminar/workshop, or finding a mentor or coach to help you.
