For information events/campus visits business casual is fine.
For interviews, which are conducted by alumni, you need to wear business formal (i.e. suit & tie.)
I thought the same. Went business casual to all events, which was not a problem since most of them were after work. For the one weekend event I went to, business casual attire was indicated on the invite.
Wore suit to interview.
I think this is the way to go, even though I have seen people at events wear jeans, etc.
+1 -- jeans do not make a good impression at something like that.
On a side note, last week I saw some kid go into an interview at Kellogg wearing jeans and a sweater. Some people are just clueless...talk about increasing your chances to get dinged ten-fold before you even start to talk!
