I once interviewed for a job at a smaller company, and at the end of the interview the interviewer leaned forward and asked me with desperation in his voice "why do you want to start here", with the implication "are you mad??" hanging in the air.. Needless to say, I declined the job and that was probably wise.. Moral here is that some things you might not get a perfectly clean answer to, you might need to read between the lines when you visit the company, walk around, shake hands.. Listen to what the interviewers casually talk about during lunch etc..

Nobody expects the spanish inquisition!
