interviewed for a job last year and was told that when i started i would be required to write down 300 names of people that i know. then i would have to call each one of those people. 
Was it Northwestern Mutual? I had an interview for an internship with them after my freshman year and it was very obvious that it was a scheme.
no but i also had a friend intern for them and badgered not only me, but asked me for names of anyone i knew.
so it's just as bad when that person calls a friend of yours and says "hey i got your name from your friend, _______."
he was a really good friend, was very awkward and i didn't want to not help him. 
I had the same thing happen with NW Mutual. Went in for the interview/recruiting scam because I figured interview experience wouldn't hurt, and at the end they asked for 10 names and numbers. I gave them legit names, but changed the phone number by a digit. The interviewer was a pretty hot ex-EMAW cheerleader though, so we talked 'Cats for a bit.
Got the Quixstar pitch three times. First time was an interview for a "marketing/business internship" (pyramid scheme) the summer after my freshman year. Second time, a college roommate got in to it and gave the pitch to me and the 2 other roommates as we

and

at him.
The third time, and old high school friend/acquaintance asked me and another buddy to help him move some furniture pretty early on a Saturday morning. This [redacted] had us move one couch across the room and maybe a chair, then sat us down and gave us some of the Quixstar sports drinks and tried to start in on the pitch. We basically told him to eff off, and left right away. Don't think I've talked to him since.
