Pros
I worked with some really good people while I was there. They cared about what they were doing and were very competent. The benefits were good.
Cons
I worked in the creative department based in West Kingston, RI and as I understand it, there have been some major changes since I was there starting with the firing of the CMO. But basically he ran a department based in fear. The managers were all friends and hold-overs from the old APC days and were grossly incompetent. They basically outlasted any real talent that may have been there. Since they were all fearful of the CMO they ran the designers and writers into the ground. The mantra was that quantity over quality. 150 mock ads/ concepts produced just to please a suit, most of which weren't very good? You better believe it. This resulted in long hours. Plus when "important" projects came up, we would get emails telling us the weekends we were going to be working for the next 7 weeks. It was just ridiculous.
