There is nothing better that a SIGGRAPH conference to get your EGO deflated.
I remember quite clearly, the open portfolio review process in SIGGRAPH 98 that was just plain brutal. People were leaving in tears from that room.
By the way, I do agree with beaker. You have to do your homework, BEFORE the conference. If you are serious about getting a job, you should contact the companies before the conference, and tell them that you are coming over.
But if you go only to party, there are more than enough parties to satisfy that need.
PS: Does anybody remember that “Matrix Chick” in one of the booths at SIGGRAPH 99?
