I was wrong no matter what I answered. (I adjusted my answers with each person, based on feedback from the previous interviewer.) This was after several phone interviews, so I assumed they would have understood why I was there. Furthermore, I have read many articles that indicate the best option when you're told you're wrong in an interview is to RUN! If you do get hired, it's quite possible that you will never be right anyway, and become an office whipping person. At least that's what the 'experts' who write the articles say. :-)
