Pros
The casual dress code and relaxed office atmosphere is nice. You get to work with some of the world's biggest retailers. Hard work is eventually rewarded. There is an opportunity to travel. They have some fun company events and if you're a top-rated performer, you will get a healthy annual bonus.
Cons
Late night and weekend work is the norm. Poorly trained middle management plays favorites and can act very immaturely. Senior management encourages a competitive atmosphere amongst fellow employees, and standards for who gets promoted differ from team to team, causing some internal angst. Technology issues cause many headaches for client services. Rumors spread fast and senior management takes their sweet time before releasing any internal communications.
