I just interviewed at MWU September 2nd, 2008. You don't have to write an essay, and all of the questions I was asked were straight-forward; in other words, no geography or political questions. Interview was by a dentist and community member of admissions committee, was open file, and was laid back with the focus on getting to know you as a person to see if you are a good fit for the program. Lunch, tour of sim lab, campus, and student apartment complex as well as a boring financial aid presentation rounded out the day. We were also asked to fill out a survey concerning the interview day so they can improve it.
