Pros: Facebook provides a vital service to billions of users every day, connecting people. By doing so, it has been thrust into a role that addresses some of the toughest issues that society faces today. At Facebook, everyone will have a strong voice on how we tackle these issues.

Cons: The work will be challenging, and you may face seemingly unwinnable choices where there will always be a portion of the user population who will hate the choice you make. If this doesn't excite you, then this is not the place you want to join.

Pros: There is a huge potential for impact. If you have a great idea and can convince others to join you, there is very little process stopping you from building awesome new stuff and shipping it to the world. Practically everyone I know, and everyone I meet, has used the software that I've written. The company culture and values are amazing, and everyone is totally on board with them. There is no politics or infighting, and everyone is really on the same team, trying to make Facebook better. Facebookers are extremely smart people and super passionate about their work. We aren't afraid to take on new risks or big challenges. The technology stack is mind-boggling. When I started at Facebook a few years ago, every day I learned something that made my jaw drop. The same thing still happens to me on a regular basis years later. Mark and Sheryl make a great pair of leaders that I have the utmost confidence in. There are excellent learning and development programs/opportunities that help you progress in your career. The benefits are obviously awesome too.

Cons: We don't really do April Fools' jokes, which is kind of a bummer. There are some dragons in the codebase, and they breathe fire.

Pros: Perks are so great (3 meals a day, 5 days a week; microkitchens; ping-pong; no set hours; they do your laundry for you, etc). You're given a good deal of freedom in what you choose to work on. You have huge impact (you push code to a billion+ people weekly or even daily).

Cons: Expectations are pretty high (this isn't necessarily a bad thing). It's a software engineering gig, so work is somewhat isolating, but no more so than any other similar job.
