Pros
The people are the best around. They are fun and it's a fun environment to be in.
Cons
That being said, it's all just about putting on a facade of "fun". People get promoted that have no qualifications and are complete morons, but because they're best friends with the upper management they get promoted. The project management department is in shambles. Honestly, some departments are awesome while others are awful. It's like working for completely different companies based on what department you're in. Some people deserve where they are, others have no business working there. It's very inconsistent. The benefits are average. Nothing awful, but also not amazing either. Free movies occasionally. Random Christmas parties that I really don't enjoy going to. But they do give cool gifts for Christmas. The management likes to send you a Christmas Card to tell you how much they spent on letting you go to free movies to somehow makeup for the fact that their pay is crap. I worked there for years and years and still was paid crap. Work/Life balance also depends on your department. Mine was awesome, but I heard rumors that other positions you are pretty much always on-call. Also Dave is insane. Beware.
