HI guys - good luck on interviews.
FYI about the clothing (everyone has their own opinion, but...) Arizona is REALLY laid back about clothing. Seriously. (I have lived here all my life (save 3 years in LA for college). )
WE can always tell which type of students are interviewing based on what they wear: DO applicants are the least conservative (may find a few greys or purples in their with the navies and blacks), then Pharm, and finally PA.
Of course wear something nice, but at a school where the head of anatomy often comes to lecture in shorts and the Assistant Dean of Students is also often seen in denim shorts, I wouldnt stress about it too much. This is a laid back school.
Good luck again!
