You probably do not want to be brutally honest in answering this question. 'I'm dreadful at time management' or 'I have anger management issues' are not advisable, especially if you are dealing directly with customers! Similarly, 'I don't think I have any weaknesses' suggests that you are not being honest, or lack self-awareness. What should you say then? There is no doubt that this can be a difficult question to answer. A common response is to take a weakness that some people might not regard as a weakness, and provide examples of what you have done to work on it.
