I'm not applying to Arizona but i just got off the phone with a friend of mine in Tucson who is applying to U of A and we were sharing interview experiences. From what she said it was really a chill interview, no ethical questions or anything like that. They talked about the usual stuff, why medicine, why Arizona, where do you see yourself going with your career. She's older, non-trad has extensive clinical experience as an allied health professional so they talked a lot about that and why she wants medicine after having had this other career. Nothing too hard and they guy told her her thought she did a good job and he would write her a nice report. This was a physician in private practice in Tucson. Hope that helps and good luck!
