When you arrive you'll be given a folder with your name on it containing information about your interviewers and you'll be assigned to a group (A,B,C..) which results in some of you interviewing while the others are on a tour.
You'll go into a classroom, mingle with some first years like
@samac , and watch an introduction video and have a brief intro from the associate dean and director of admissions. Your interviewers will come in and call you back with them.
My interview was very conversational and was given by 2 professors. Some of the questions I was asked:
What brought me to KYCOM?
What was my biggest regret of college?
How did I adjust my study habits when I was presented with a topic I had difficulty understanding?
How would I explain my learning style?
Questions regarding my research
What did I like in particular about my shadowing experiences?
Finally, I was grilled regarding my job. I work at an inpatient rehabilitation hospital so they were very interested in what my job consisted of and how the experience has affected me.
You'll be fine, just don't go in with rehearsed answers and speaking 1,000 words per minute. Review your personal statement, secondary application, and the information they give you about your interviewers. KYCOM is VERY mission oriented in regards to producing primary care physicians, so I would recommend your interest in going into primary care (even if that's not the case) to be brought up at some point during your interview.
You'll be fine. It'll be here and over before you know it, good luck!
