No one specified that the interview details should be kept under wraps, so I am going to be detailed. Someone let me know if this is going too far, and I will happily delete it. I will not say who I interviewed with. The admissions team does scope out your SDN accounts, and knew who I was and where I had interviews so far. So be professional on here.
If you have any very distinguishing characteristics, be prepared to talk about them. I talked 20 minutes about my major. Also know the school's mission and be able to give examples of why you fit the mission. Be prepared to talk about your views about the Christian faith/differences in your faith to Christianity/your lack of faith, and even to pray in your interview. One of my questions was, "has anyone ever discouraged you from pursuing medicine?" They asked me about my favorite volunteering endeavors. Overall very conversational. One of my interviewers was more conversational than the other. I was asked how I felt about the new health care laws. Do not be nervous, be yourself. I was so nervous at first, as it was my first interview, but they take good care of you and they make sure to make the day very positive.
I personally did not get the "tell me about yourself, why do, why medicine" questions that I was expecting, but I'm sure different interviewers ask different things.
They will send it to you a few days before. They are overloaded with applications and are holding to acceptance meetings this week, so I imagine they will get it to you asap. Good luck you will do great!
