I interviewed there on 11/17 (and got accepted today--
WOOT WOOT!!
). The facilities are fantastic--brand new comfortable building, great hang-out areas, good gym, labs are very impressive, and the classrooms are, well classrooms. It's a small campus, only 22 acres with only 1300 students. The students are the friendlies group of people I've ever met; very chummy community feeling. Curriculum is pretty standard, but pack your bags for your clinical years, because you probably won't stay in Des Moines, you'll go out of state unless you have wife and kids.
Interview advice? This school is BIG on OMT--know about it, expect to be asked about it. If you're not interested in OMT, don't go to the interview, they'll see right through a fake answer. One of my interviewers (a DO) voiced her disappointment in me never having RECEIVED OMM. Expect to be asked "Why DO?" Interviews are pretty short and my interviewers prided themselves on not asking the typical difficult questions (e.g., ethical questions, or major societal/medical issues in our country). The interviews are pretty laid back, don't stress out about it.
One more thing: Des Moines is small, and COLD. Pack accordingly. You won't go outside during your interview day because all the buildings are connected via underground tunnels.
Good Luck.
Let me know if I can help you anymore.
