I gotta confess: I'm one of those guys with over 1200 Facebook friends, 800 of which belong to my school. I decided to look through the people who graduated in 09 and 08 just to see where they are today (these are Ivy guys).
What I found was that many people didn't list their current employer. One guy had, for example, "- Summer Intern" and " Intern" but they were for 2006 and 2007...it's now 2010 and their employment dates end at 2007 with a . Another guy, who graduated in 2008 had "MTV Internship" but that was for 2006 and his employer list ends there. A whole bunch of people who graduated in 2007 didn't even list their employers nor did they join any groups (like "Microsoft Engineers 2009!!!!!!!!! yay!", for example). A couple of them are in grad schools so I didn't count their employment info.
Are all these guys living at home or don't feel like giving out personal info or what? All their Facebooks are still very active.
