This can be a tricky question to respond to, if you suggest you have no weaknesses you're going to appear as a lair or egotistical. You should respond realistically by mentioning small work related weaknesses. Although many try to answer using a positive skill in disguise as a weakness, like "I expect co-workers to have the same commitment" or "I am a perfectionist". However, it is recommended that there is some honesty and the weaknesses are true, and then emphasize on how you have overcome it or working to improve it. The purpose of this question is to see how you view and evaluate yourself.
