The most intense and rewarding experience of my career.
Pros
Access to people who are smart in ways that you can't even comprehend. Incredibly challenging work, and opportunities to finally do things you've wanted to do elsewhere but couldn't because of the size or political currents of other companies. You really care passionately about making the world more open and connected and want to be surrounded by people who are dedicated fully to making that happen. You want to work with people who not only help you experience all of the above but who are also the most respectful and inclusive people you've ever met. When we say we want you to be yourself completely at work - we really mean it.
Cons
The pace and scale of what we're doing is insane. You're regularly exhausted but in a good way. Facebook isn't just a company, it's a kind of movement that people dedicate themselves to in ways that transcend the traditional bounds of employment. You will make life-long friends who will become a part of your life beyond 9-5.
