Pros
Good compensation, good benefits, and nice offices. Extremely smart and talented people work there.
Cons
Extremely political. There is no clear direction, and constant change and ambiguity are the norm. Your team members are not encouraged to help or collaborate, rather your encouraged to all be "leaders". So it's a very "every man for himself" culture. There are constant conversations going on about you and your performance at all times, and you never know who is a part of those conversations. So, for example, if you work on a project with someone, it's not just you working on a project...it's a test. Because that person was likely advised to work with you by a leader so that they could see how well you performed. So you're constantly being scrutinized and tested. There are tons of smart people there, but no one's really passionate about the work, so it's a very uninspiring work environment. People just endure for the money, but the culture is actually quire sad and depressing.
