I'm going to agree with Pharm OU and Ramo, I didn't interview last year so I don't have another interview to compare this to, but it felt pretty short and it really did feel more like a 'get to know you,' conversation than an interview.
I was a little concerned when they told us there would be 15 fewer seats this year compared to last year, but several of the P-1's who were there kept telling us, "Don't sweat too much, you're here for a reason."
oh yeah, to answer Lady23's question, I was in the last group, and we really didn't do that much walking. We just walked over to the student union (next door) took a brief tour of the union, then sat and talked to our P-1 volunteer guides until it was time for our interview.
