I don't know about pointers, but you'll have 2 current post-Bac students at lunch with you & I recommend that you ask them anything you can think of about the program. You'll also have a med student take you on a tour, and that would be a good person to ask about the med program.
The interview itself will be with a DO and a PhD (at the same time). They tend to be pretty laid back, but do be ready to discuss your grades, MCAT, etc.
Feel free to PM me.
