The main perk at Facebook is working with brilliant people and getting access to top-level execs. How top-level? Mark Zuckerberg invited all the Engineering interns to a BBQ at his house. I had a meeting for high-level discussion with the VP of Growth, Chamath Palihapitiya. It’s no small deal. These people have grown companies from idea to billion-dollar scale. They must have done something right. To be able to interact with them and pick their brains is something that very companies, even Google, cannot do easily.
There are also the likes of Andrei Alexandrescu and Bret Taylor. It’s hard to resist the temptation of working for Facebook with this team.
Oh and BTW there are also other perks such as free food and laundy (with the bane of my existance, folding, taken care of) and amazing offsites, and ripsticking. But those are of marginal importance.
