While these all work a little differently, the basic premise is the same: representatives from each company stand around a large room, pass out information and collect resumes. Even if you have already submitted your resume by some other means to these companies, and especially if you haven't, it is imperative that you attend this function and generate some face time. However, this is not as easy as it sounds.
