Pros
As a global firm, this is a good place to get experience working on a variety of projects. They are very safety conscious and encourage employees to be aware of surroundings when working offsite. They give money to help environmental programs overseas. I definitely was impressed by the leadership outside of the Atlanta office. They really seemed to want to get junior staff plugged into cutting edge projects.
Cons
Leadership in Atlanta would refuse to communicate with staff, local HR representative told me very blatantly that I was "a trouble maker" for asking for constructive criticism and bringing up gender/salary questions. Many people left the same year I did because local leadership performed unethically and made allowances for behaviors by staff which was offensive and against corporate policies. They expect you to be "100%" billable which means working in excess of 50 hours or more. In December I worked two 80 hour weeks and was not given a day off or compensated financially afterwards.
