Day Girl Question:

More likely than not, the interviewer wishes to see how much you know about the company culture, and whether you can identify with the organization's values and vision. Every organization has its strong points, and these are the ones that you should highlight in your answer. For example, if the company emphasizes on integrity with customers, then you mention that you would like to be in such a team because you yourself believe in integrity.

It doesn't have to be a lie. In the case that your values are not in line with the ones by the company, ask yourself if you would be happy working there. If you have no issue with that, go ahead. But if you are aware of the company culture and realize that there is some dilemma you might be facing, you ought to think twice. The best policy is to be honest with yourself, and be honest with the interviewer with what is it in the company culture that motivates you.
