i interviewed last month and my interviewer DRILLED ME! i had nonstop questions for about 40 min, but i loved it--i prefer good questions and conversation to a general 1 or 2 impersonal questions. He seemed to have my file memorized! it seemed everyone was different though, i know some people only got a few questions (ie. 'why pittsburgh?' and 'why dentistry?'). either way, i got in, so good luck to you too!
