It's a good company to work for. There are about 40,000 employees world wide. Many of the employees and contractors work at customer sites (Pentagon, Military bases and Defense contractors etc). The pay and benefit's are ok, but I think they are higher for people with clearance. The company is employee owned (although I think we have little say) and I think they eventually want to take it public.
