Pros
Top quality engineers, management who doesn't slow you down or want to track every time you take a poop. Seriously, this place was built for speed. They empower the engineer and allow you to do what you need to get done without fear. At first I just assumed this was like every other corporation who claims to empower their employees and move fast. Nobody wants to move slow but Facebook is serious. It really is different here and in a great way.
Cons
People tend to want to tell you about how they hate facebook or how they don't use it because "xyz" when they find out you work there. I've just started telling people I work at the NSA spying on their porn browsing habits. The other major con is Zuck never responded to my friend request. I feel so rejected. I do wish they had a daycare..
