i'm not sure if u r interviewing for a waitlist position but i assume most schools try not to do that (ie - interview when they are completely full). i know that when i interviewed in early feb, the class was nearly full (i have this info from a friend's father who is on faculty there). its also more difficult if you're female as the school is 70% female (also heard from this from the same faculty person) so they are accepting less females this year esp if you're like me and applied late though it turned out ok for me. but my advice is don't worry whether its a waitlist interview or not (you'll never know anyways), just concentrate on showing them your best and rock the interview!
