I did an interview like that once and ended up being "over qualified" and tried to talk the interviewer into hiring me anyway. It is funny how weird and rigid some companies' hiring practices are. The one I interviewed for was a huge insurance company and they said I was over qualified because of education and they didn't want me because I'd get bored and quit! It took too many interviews like that before I realized that I didn't want that kind of job, where other people are telling me what I think and feel and need.
