Pros
I can see for entry level employees how this could be a fun place to work. The cafeteria is creative with cuisine and there are some fun events. The technology stack could certainly be a kickstarter to a great career elsewhere. The financial industry will be around forever, so as long as this company makes enough innovative product that their core clients keep buying them, the company should be safe. There are a lot of really great people here.
Cons
More politics than I would expect. More dishonesty than I would expect. Lack of vision outside of core competencies. A hugely cult-like culture. Indoctrination is fine, but I think it really prevents employees from seeing the problems at the core. Hours are long, but that is to be expected. There are a few managers who will severely burn you just to cover their own tails.
