I sent mine in yesterday, too!
Does anyone know if ISU has a dress code? I think this was mentioned during interviews, but I forgot. If so... I need to get a new wardrobe; I'm pretty sure my collection of school and nerd shirts will not be allowed. Haha.
On Thursdays we dress up. Some guys/girls wear suits and there are others that wear khakis and a nice shirt. I wear black pants and a nice shirt. The idea of Thursday is dress like you're going to an interview. The other days of the week you can wear jeans, t-shirts and sweatshirts. So I doubt you need to buy a whole new wardrobe unless you only wear yoga pants.
