Atlanta office is shutting down and positions are being relocated to Chicago. With that said, cons:
-Very clique-ish environment - especially from Director-level on up
-Jobs generally pay less than the market
-Work is tedious and implementation heavy - especially if you are on Client Services team
-Marketing efforts are behind the times and there is little effort to change
-Attitude of the Chicago office is piss-poor to say the least
-Operations departments are less than cooperative when it comes to any type of change. You will experience push-back and tremendous tit-for-tat in EVERYTHING you do.
Good luck. You will need it!!
