Be confident and be yourself. If there are any "flags" to your app., like low gpa, multiple colleges/universities attended, etc. be prepared to explain them. Otherwise, have fun. The day is really relaxed. Everyone is amazingly friendly. The students that give the tour have no say in the admissions process so feel free to ask whatever you want of them.
When I went, we had lunch with the students that did the tour, the dean of admissions, her assistant, the 2 recruiters, and the student service guy. We were all laughing and joking so it was a good experience. I was interviewed twice by the dean, once before lunch and then again at the end of the day. The last one is where I was given the acceptance letter. There were no hard questions or anything. I was asked about a comment in my ps about why I wanted to pursue podiatry. Overall, it was a fairly easy interview. I really enjoyed the day. I can't really know how long the interviews were. After the first one, the other interviewees said I was in there awhile but it didn't seem all that long. The second one was fairly short, too.
Be prepared to walk off and on. They let you see all of the school, which is kinda moot since it is moving.
Don't be nervous. You'll do fine. Like gangrene said, there is feedback online. I posted mine there. If you have any specific questions or anything, PM me. Good luck!
I know people talk about it being a lower level school, but I really felt comfortable there (even though I know I can get in at the other "top" schools). Go with your gut. Don't let other people sway you.
