Pros
At first, Bloomberg seems great. It's full of seemingly smart, motivated people. The pay can be good. Resources are never a problem. When they want to do something, it gets done. The first couple of years are great and full of excitement.
Kontras
And then time starts to pass. Things can start to get political. The most mediocre start to rise into upper middle-management and beyond. The single easiest way to get ahead is to be a yes-man. Never question anyone above you. Do what you are told, and like it. Treat those above you as if they were gods. Stoke their egos. The rules and bureaucracy start to suffocate. They bend the rules for people they like, but after the newness wares off and if you threaten anyone above you, the rules will be applied with full force. It's disappointing to work so hard and then to be cast aside. They will work you until there is nothing left.
