paq314,
I would, AT A MINIMUM, know something about the osteopathic philosophy, its history, who A.T. Still was etc..etc..
I was asked a couple of questions of this type when I interviewed at UHS and at TCOM.
Also, be ready to explain why you are chosing osteopathic medicine, why would you want to come to 'our school' etc.. There will be other questions and topics that will be no different from interviewing at any other medical school. (osteopathic or allopathic)
Whatever you do, don't make up some bull****, grandiose story about anything! Interviewers can smell a snow-job a mile away! If they ask you something regarding some sort of hypothetical clinical situation, and you don't have a clue, then tell them that you don't or tell them that you are going to need a little more information before you can answer the question. The ability to realize that YOU DON'T KNOW enough with the information that you currently have, admitting that, and then trying to obtain more information instead of just "punting" is a trait that they are probably looking for in a good student doctor!
Last but most...don't worry! The interviewers aren't there to hang you up by your heels! Getting an interview is a big portion of the acceptance process. They (the admissions comittee members) have already seen and scrutinized your application and qualifications to the nth degree! In the interview they want to see that you can communicate intelligently and effectively. Obviously, as physicians, communication will be a BIG part of our job. So don't worry, relax, go into the interview and be friendly, courteous, and by all means...be yourself!
Good luck and have a great New Year!
