Pros
Flexible schedule (sometimes); cafeteria and medical staff on site; good health benefits
Cons
I was on a team with several young engineers who were in the US on work visas. Because they tend to be single and new, they are easily "inspired" to work 65+ hours a week. This was used against my coworkers who limited their work hours due to family obligations. Also, the 360 Review process and the 5-90-5% approach is outdated. [That's where you give your top 5% of people a nice raise, 90% a standard cost-of-living increase, and 5% are ushered out the door. It is based on the belief that you keep the cream of the crop and eliminate the chaff. The problem with this is that someone HAS to get axed and it's almost always support staff who are perfectly competent workers.) Compensation is low compared to other people in my position. Management in my area played favorites.
