I went to one of those a long time ago... it was pretty packed inside.
I don't know if it's the same thing but when I went there were just tables with people who hand out application forms and answer q's... you have to like fill it out and hand it in with your resume. There wasn't much room so i had to go in a corner and kneel while writing. I got so hot that i jsut took all the forms home and never filled them out..
