Congrats, guys! Listen to OMD--KCOM interviews differently from other schools. If you are invited for an interview, you have already passed the interview committee at least once. Your interview is a final determination of your "fit" at KCOM. More important at KCOM than intellignece is attitude, sincerity, and motivation. You passed the intelligence test or else you wouldn't have been invited. Now stress to your interviewer what makes you DIFFERENT. Be comfortable, be yourself, and, above all, be honest! They will overlook mistakes and nervousness if they can see the real you: I accidentally said to my PhD interviewer, "Oh, your just a PhD." That elicited quite the response! However, she could tell that I was nervous and slipped my tongue, so she obviously overlooked it--I guess since I am here! Have fun on your trip and enjoy this time!
P.S.--Come with questions; they'll expect them and you shouldn't be unprepared!
