I interviewed in Oct. (I think) and got accepted about two weeks later. I really think it is an excellent school. The only thing I did't like is that you don't stay all 4 years in Duluth.
My interview day was just fine. I had very friendly tour guides that really seemed to love the school. With that being said, one of my interview sessions was probably the strangest experiences of my life. I won't give you the name of the person I interviewed with but you will know who I am talking about if you get him/her. This person was really out there and asked crazy questions...I pretty much laughed at him/her the entire time. Just play along, keep your cool, carry on a decent conversation, and you will be fine. My other interview was pretty normal. Good luck!
