People argue that this can be a difficult question to answer, because you obviously can't say no, and saying yes may appear as an invitation for the company to exploit you. But if you think about it, you're bound to do overtime at one point or another. Also, depending on the nature of the work, overtime may be inapplicable because the work itself involves rendering long hours. Moreover, if you're applying for a managerial position or a position that is focused more on projects than operations, note that there may be no overtime pay, and overtime may simply be a given.

If you do not feel comfortable saying yes outright, you can sidestep by expressing your agreement or determination to deliver what is asked or needed of you. This has the additional benefit of showing you as being goal-driven rather than a clock-watcher.

☛ Strengths are skills or values you feel are an asset. Rather than just listing these down, be more specific. Values are relative, therefore tricky. You can be patient, but patient to what extent and in what context? Are you able to endure instructing someone who can't seem to understand you, or are you uncomplaining of people who are late? You can also give brief examples to be better understood.

☛ Weaknesses are skills or values you feel can be a liability and need to improve on. Since these may seem like points against you, turn the negative into a positive. Give weaknesses that, when looking on the bright side, can also be a strength, and highlight that fact. You can also give a weakness that you've created alternative solutions to or are currently working to correct. This article on About.com has some great suggestions and examples.

Never refuse to answer these questions or give vague and non-committal answers since this will give the impression that you either do not know yourself well or are not confident enough in your abilities to recognize what you're best at and what you need to work on.
