Pros
I had some amazing peers--smart, creative, hard-working. At the individual contributor and lower managerial levels, there was generally a sense of camaraderie and a willingness to go above and beyond to help others (both clients and fellow employees).
Cons
The company rewards bad behavior and has some genuine bullies in its leadership ranks, a certain "Distinguished VP" being a prime example: he would loom over people while they worked, often assigning essentially impossible tasks and then berating employees when they couldn't accomplish them--either that, or he would ignore you completely, providing zero feedback on your work before unceremoniously reassigning it to someone else. Your needs and preferences as an employee don't even enter into management's thinking; you are just a means to an end--more research, new clients, bigger contracts. Don't bring your real / whole self to work. I saw AMAZING people (who have since gone on to succeed elsewhere) become utterly demoralized and, in some cases, humiliated by management (if they decide they don't like you, they will treat you worse and worse until you quit). I would never work here again nor recommend it to anyone else.
