Our school usually interview about 5k students, roughly 500 people interview for a class of 108 seats. So I assume they accept between 150-200 people.
For the interview, you really just have to be yourself and showcase why you deserve a spot. As cliche as that sounds, but they will know who you are by the end of the interview day. When I interviewed, I honestly did not read any books, or MMI articles or anything like that. I just knew why I wanted to be part of this school, and why I want to be a DO. The interview process is fun, the faculty are amazing and very supportive. So relax and don't sweat it, guys.
