Pros
Some very very talented people. It is a very collaborative and egalitarian environment. Company is starting to grow its conceptional/marketing (versus design) prowess and making strides.
Kontras
Output of work is not consistent and usually either very good or very bad. Varies depending on whether you get the "A" team or leadership is paying attention. Teams (especially creative) can get very large with no one "on first" making final calls, until up against the deadline. Drives a lot of doing-over at the last minute. If I were a client I'd be concerned about this driving up my fees. They are still a very production-driven shop with many of the senior executives not really fully on board with the migration to marketing/advertising work. So there are camps, which makes for mixed signals from leadership sometimes (even though from the very top it may be clear)
