Proven Process has a wide variety of projects going on at any given time, and a group of great Engineers doing the designs.
Cons
The medical benefits are the worst I've ever had through an employer. There is very little flexibility offered in terms of time off. Hours above and beyond what are normally required aren't recognized when someone needs a day off for family or personal reasons. Some Project Leaders shouldn't be leading projects. A good engineer doesn't always make a good Project Leader (and vice versa).
