I had an interview last January at AZ and I can tell you how my experience there was. I was nervous too, but after I got there, several students said hello and assured you not to be nervous and to BE YOURSELF.
We did stay in a group most of the time. You do have to play well with others in a group activity, like the airplane crash in the desert. It is not to see if you die or kill your group, but to see how well you work with and in a team. This is VITAL in dentistry. Then you write and essay or go to your interview. I had 3-4 people in my interview. It doesn't really matter, because you will always be nervous in an interview. They will ask you questions that others have already posted and the key is CURRENT events and basic geography. I was asked who the presidential candidates were at the time. But just like everyone who new a little, I memorized some capitols of Europe, Africa and the US. It gave me something to do on the plane. 🙂 Ask someone close to you, (that will be honest), what your strenghts and weaknesses are and know that!
After my interview the student that sat in on my interview said that I had done the best that she had seen. That made me feel good. So, if you can get the cahnce maybe you can ask the student, if there is one, how they think you did.
All in all, I loved the experience and I would definately go there in a heartbeat. They are very warm and family oriented. If you don't want to be a zombie by the 2nd year of dental school and question why you ever placed yourself here, then apply to AZ.
Sadly to say, I did not get accepted, but I am going to try and strenghten my stats and apply next year.
Hope this helps. Oh I work with a dentist that teaches at the UW dental school so I can tell you a little about them too. Best wishes!! 🙂
