Pros
Look at all the positives mentioned in all the reviews and just believe them. This is the company that gave me hope about Silicon Valley. I would work again for the founders and a few other leaders (Ken, Marcus, Dan) in a heartbeat. Just crazy good. I have been privvy to some of the strategy discussions. Amazing clarity of thought, no turf warfare or political agenda and just swift decisions.
Cons
While I have seen a good deal of positive people I have also encountered a few rare pockets of negativity first-hand. Be prepared to see 2-4% bad apples. You will kiss lot more prince/ princess than frogs, metaphorically. I have also seen a sense of entitlement among some old-timers. I have seen people working 6-7 hours a day. I have also seen old timers (geniuses) who get a sheer mountain of work done in single 8 hour window - almost 2-3 times as that of others. The average works out fine. But it is perplexing when you see people arriving at 10, taking 60-90 minute lunch breaks and leave at 5:30.... and the entire management cadre thinks that everyone is holding themselves accountable. And if you want to talk about it, tread carefully - this is a very sensitive topic. If you bring this up prepared to get yelled at by several people, including a few senior leaders.
