Pros: Good food and people overall.

Cons: Work-life balance is not well.

Pros: Disclaimer: This is my particular insight into working in engineering at Facebook. The people here are smart. Very much so. The people here are driven. Even more so. If a challenge comes up, people come together and solve it and do it correctly; the buck doesn't get passed. The product is very engineer-driven. If you're interested in product work but love the task of actually building it, Facebook is a good fit. I was choosing between Product Management at Google and Engineering at Facebook, and I think I made the right call for me.

Cons: Biggest con for me is that they are in Menlo Park, and I live in San Francisco. They run very efficient shuttles, but that's only second best to having a close office.

Pros: Facebook's products are used by more people than anything else. The company's mission – to connect the world – is good. There are many, many choices of projects for software engineers, and you get to pick your team.

Cons: Facebook is a big company with rules. If you are a software engineer, you are compared to all other software engineers. If you do part of the job of a software engineer and part of the job of something else (PM, manager, analyst, etc.), it will be hard to evaluate you. Also, it is common to have a lot of manager changes.
