The interview was very conversational at Creighton, the only real interview-type questions I was directly asked were, "tell us about yourself" and "why did you choose the distance pathway?" I'd recommend you be prepared to discuss your non-academic experiences (i.e. volunteering, work etc) because the interviews were closed-file and they have already looked at your transcripts and pcat. I have volunteered at a dispensary for low-income patients and my interviewers were really psyched about that; we talked about it for most of the interview. They don't quiz you on the school or anything and the interview day activities tell you all about Creighton and its history anyway. Be confident and affirmative and you shouldn't have anything to worry about. Hope that is somewhat helpful.
