Vantaggi
Some awesome engineers around. If they don't see you as a threat, you will get to learn a thing or two. Decent perks.
Svantaggi
Rampant nepotism. Managers hiring 'loyal' people from their previous orgs, their boss's/peer's wives, and they all live in a happily ever after, where they scratch each other's backs. If the San Diego overlords are happy(or you can make it look like you are doing good), you can get away with anything. Even if the entire team report who reports to you, complaints to upper management, they will not do anything because, end of day its all about business. There is no thing as ethics, decent behavior or even decent language. You will be punished for not being complacent, threatened for asking questions. Have personally witnessed employees tortures and pushed into depression because they could not get along with the middle management.
