Pros
Company has a structure very close to a flat hierarchy. Most people are really smart, and fun to work with. Company is fairly keen towards keeping its employees happy.
Cons
Compensation is not at par with the best, considering the sort of talent they seek. They have their philosophy around why it should be that way, but the times have changed since the time of inception of this company and so should their philosophy or else they will continue to lose good talent to that bunch of upcoming smart companies who offer almost everything that TW offer, along with exciting challenge and good pay. Another thing is that they seem to be stuck up in terms of the kind of projects they are taking. One might feel like a bit unused to their full potential. Some of the big long going projects have a fairly large number of people who are mere cribbers, so that sort of negativity on the floor sometimes hurt your productivity or the satisfaction that you might have otherwise acquired from your work.
