What questions can I ask my interviewers?

Those five or 10 minutes that they give to me in the end of the interview to ask any question... the first question, obviously I'll ask them for any advice they want to give me for working in the company that they are working in. The second thing I ask about is the role that they are looking out for me to fulfil, and especially whenever there is a company which is having a broad variety of use cases that they are looking out to solve. So I'll ask specifically which use case or which kind of project or which kind of team that you are going to put me in.
