On Thursday I'm going to a Co-op/Internship Job Fair at my school (San Jose State University). There are going to be like 130 companies there, and I'm going to try to talk to companies like Cisco, Microsoft, Agilent, Compaq, IBM, HP, about MIS Co-op/internship opportunities. So, what should I wear to this thing? I don't want to look super dressed up ( that means so suit) because it is a large job fair that will require some walking around, but I don't want to look like a slob. I want to look professional and good enough to make a good impression. Anyone have any ideas? I'm a guy by the way.
