I'm 24 now and made $900 pretax in FB (no college loans).

I think i'm lucky that i joined Facebook after IPO but when the stock was very low. My new grad offer was $280k (negotiated like a VC with tons of counter offers from GOOG, DropBox, etc...) and stock was $19 the day i had joined around Sep 2012. So, i got ~14000 FB shares. I sold all my vested shares(~11000 [9500 vested on my base offer and 1500 out of my refresher grants over last 2 years) at $80 very recently and leaving the company for $1M offer with a startup.

Total Money i made pre-tax: $900k. Bought a Porsche and chilling out in LA for a month now before my next gig. Everyone call me as a lucky kid.
