When I interviewed at California, I only had one interview with the Podiatric physicians. It is a group interview with 2 doctors. They basically asked why podiatry and the school. I heard that the interview now is more academic since there would be 2 interviews throughout the day.
At Arizona, they asked the same questions and more academic questions. However, since the california school has 2 interviews throughout the day, the questions would be similar to arizona.
At the interviews, expect at least one question from each interviewer. They really do want to get to know you and see if you can handle the program. Pm me if you have more questions.
