Meta reviews

Despite having several thousand employees, you can still have an impact, and it doesn't have to be "wrote the messaging system", it can be as simple as "made something more efficient, saving hundreds of thousands of dollars over a year", or "enabling someone else to be a rock star". There are great challenges in the infrastructure, and it's a first-hand experience of (at the heart) simple systems interacting in complex ways. Lovely food from the on-campus cafe (really and truly I'd call it a restaurant, the food is that good), break out areas for peace and quiet, and generally excellent and smart co-workers.

+ Smart/energetic people around you to make yourself better + Relative flat management for a company at this size + Projects that influence people + Probably the best café in all IT companies at the moment. Thomas Keller, Gary Danko theme, etc. + Work for fun. You can still keep a life if you are good at what you are doing. :)
