Pros: Great company to work for. Interesting problems to solve. Smart people.

Cons: Quite bad work-life balance.

Pros: Great place for young kids out of school. You have to "play the game".

Cons: Facebook has created a truly toxic environment; it is hyper-competitive. Rarely a day goes by without talk of being impactful, impending reviews, or cross-calibration. So much time and effort is wasted on internal posts shamelessly describing improvements (which are often just fixes to your own shoddy work). Like working in a chicken coop? Beware of role deflation: you will get a pay raise when you join, but typically, you will be just another software engineer (like any new grad) – regardless of your experience.

Pros: Autonomy and freedom to work on projects you're interested in. Great bootcamp training. Everyone is incredibly intelligent and executes well.

Cons: It's starting to get fairly bureaucratic, even in 2015. I can't imagine now, but I've heard it has only gotten worse.
