Pluspunten
There are some very smart subject matter experts - however be careful they're not ERPs (see Cons). Apparently it looks alright on your CV. It's easy to stand out - just do stuff. The place is full of "would-of", "could-of", should-of" people who just snipe and offer views or 'strategy' (half these people wouldn't know an actual 'objective' or 'strategy' if it bit them) from the sidelines, but won't actually get in and do it. There are some great people who just cut through all the crap (see Cons below) and bring things to life. If you can find them you might keep your sanity.
Minpunten
The place is full of ERPs - emotionally retarded people. There are many smart 'numbers' people, but they have no idea about how to deal with humans. You see this in their interactions with colleagues, clients and customers. Collaboration is seen as a weakness. A culture of fear. Some senior leadership members drive a sycophantic culture that has a number of the ERPs (see above) running scared and being even more ineffective. It's ruled by a hyperactive compliance/legal culture. As a result moves too slowly and when it does finally do something, it's often archaic. The company is too afraid to actually stand for anything so it pontificates and does everything it can to avoid actually executing. I've seen six-month projects where the first four months were taken up with arguing over a 'project charter'. Of course the project ran late.
