(btw, if you are student check out these posts; after the career fair, make students awesome, and you need to do a honors thesis)
and Student Employment actually has a lot of great resources for that. i did a few practice interviews. trust me it really helps!
i think this year was a little bit slower that most and we were in a strange location in the corner. but, i thought it was a pretty good career fair. i was pretty happy with the ee and ics students i talked with we had some good conversations. and for me its all about just talking with students; even though they don't work for me, i hope that i help them learn more about our industry.
