I got invited to a hiring event for an Apple Retail Position. This doesn't seem like a very formal part of the hiring process, so I am a little confused as to what to wear. There are going to be a bunch of other people there, so I don't want to be overdressed. Anyone have any tips or suggestions on what to wear to this event? I was thinking jeans and a polo, but if someone has been to one I would love to hear their insight.
