My school has a different process for applicants. We are required to get 3 letters of rec from faculty then we get interviewed by different faculty who write a letter based on the first 3 + the interview. In addition, I have 2 letters from DO's. Overall, with my application, each xxCOM will receive 6 letters (3 faculty/1 commitee/2 DO's). From my understanding, the medical schools like the way my university handles the process....
Hope I helped!
