What are your weaknesses

What are your weaknesses?

Answer:

The classic answer here is to state a strength which is disguised as a weakness, such as "I'm too much of a perfectionist" or "I push myself too hard". This approach has been used so often that, even if these answers really are true they sound clichéd. Also, interviewers will know this trick. If you feel they really apply to you, give examples: you could say that your attention to detail and perfectionism make you very single-minded when at work, often blotting out others in your need to get the task done. 

A better strategy, is to choose a weakness that you have worked on to improveand describe what action you are taking to remedy the weakness. For example: "I'm not a very self-confident person and used to find it very difficult to talk to people I didn't know well, but my Saturday job in the local library meant that I had to help people with all kinds of queries and that helped me a lot. Now I'm perfectly happy talking to anybody on a one-to-one basis and I've joined the debating society this year to give me experience of speaking in front of an audience." 

Don't deny that you have any weaknesses - everyone has weaknesses and if you refuse to admit to them the interviewer will mark you down as arrogant, untruthful or lacking in self-awareness
