i would tell you to be yourself...the interview is very relaxed and everyone there is very friendly....you have a faculty interview that is an hour long (they have your file with them and they know it inside out so i would review your application) and a student interview that is 30 mins long (they get to look at your extracurriculars and personal statement)...at the end of the day, you write 2 short responses about what you observed at the school....i don't remember the exact questions...we interviewed in the morning...it was right after the opening session
very relaxed day...don't get intimidated by the length of the faculty interview.. mine ended up being over an hour
