ps. It is worth looking for companies you have never heard of. While there is no point in listening to a speech from a MSFT HR drone - the small company that have their CTO on the stand who are making a cool technology might be worth your time.
Not that they can hope to get much information, just enough to filter your resume in a good or bad pile. Some companies collect huge piles of resumes and simply can't call them all. Seeming intelligent and interested in the company may be the only reason they call you from that resume.
Another problem if you are anywhere nice is that the HR dept treat this as a holiday, so you are getting a bunch of people who are in your town to drink, stay in a nice hotel and 'bond'. Having to talk to a few smelly students isn't the highlight of the trip.

Those are frequently far less "nice", and being smelly won't work anywhere. And even smaller businesses still send HR-oriented people more frequently than people they're paying to produce the core of what they sell.
