Pros: Free food, good salary, hype.

Cons: At Facebook, I got to know what "gaslighting" really means. Gaslighting is exactly the culture that management imposes top-down. It starts at the bootcamp. There, you'll be properly brainwashed about how cute and cuddly Facebook is, how unfairly it is being treated by everybody, how great and kind the Czar and his ruling gang are, and how grateful and privileged you (a despicable, useless worm) should feel to be here! Right there, in the bootcamp, they will start the abusive treatment by telling you, "Why on Earth did we hire you? You haven't submitted any code in the last 24 hours!" This abuse and fostering of your impostor syndrome will keep going on. Typical Facebook-style management is when you are repeatedly told, "I have no idea how you got here, and I don't know why you weren't fired yesterday, but OK, we'll give you one more chance." This is part of this culture! There is stack ranking! It's in tooling, in manager training materials! The fact that Facebook officially denies doing it is yet another confirmation that this company doesn't shy away from crime. Stack ranking means that all colleagues see each other as competition. When I started my job at Facebook, my closest colleague didn't want to talk to me because he knew that the better I succeeded, the worse it was for him. This is very profound and affects everybody; it's a hostile work environment. Performance reviews are a complete sham. There is one "axis" which is related to your actual performance. The other three axes (direction, etc.) are complete baloney and can be used to justify any rating for anyone. All managers are deeply ignorant schmoozers. Cult means there are plenty of taboo topics for which you'll be fired. There are, for example, internal "non-managers" groups, which are patrolled for any signs of dissent. If a person posts anything out of line there, it gets straight to their manager and HR. HR is the worst people I've met. They enforce the authoritarian rule ruthlessly and with cynicism. Working at Facebook has permanently damaged my faith in humanity. I realized that people can still do horrible crimes, given enough brainwashing. That people can treat each other like animals, given stack ranking. I wish I never joined this scam of a company, a lousy swamp filled with ghosts who pretend to be humans!

Pros: Good opportunities and pay, and good benefits. Free food.

Cons: Toxic culture, pressure from peers, and an impact-driven, short-term vision can prevent the creation of great products in the long term.

Pros: Benefits are awesome. 21 paid off is great.

Cons: Food selection is limited in the Cambridge office, but it's still great (and free).
