ha! i lucked out-and got accepted! my interview was seriously only 10 mins long. the docs interviewing me WERE LATE!!! yes!!! they were super cool, and actually, the student that was supposed to be there didn't show up, so i got off easy...the girl before me said they asked her EVERYTHING OD. sucks for her!
the interview itself is usually 30-60 mins long. however, the whole process takes a good 3-3.5 hours. it's cool...i think everyone you talk to there is part of the interview committee, so be nice to EVERYONE. =)
