This is a possible interview question to gauge your degree of confidence. An interviewer may also ask this question to determine whether you possess the necessary skills to operate effectively within a company's standards.

You can respond to this question by listing your shortcomings and outlining the steps you can take to minimise them.

Example: 'I would like to respond to this query honestly. I have been bashful around people ever since I was a child. Right now, I believe I am at my best, because I have improved my communications skills. I acknowledge that I am far from perfect, but I strive hard to improve every day. I have always made an effort to speak with more people and develop my communication abilities. But, this has had no impact whatsoever on my career. Even though I struggle with communicating, I excel at managing a team.'
