Pros
pay, PTO, benefits. they are all there
Cons
super boring, super slow. You are one of thousands of engineers, working on a small piece of a very big puzzle. The company charges the Navy for you being there, so all they are looking for are warm bodies to sit around on the clock, as they make money for every 6 minutes that you are there (GD charges the gov $100 an hour for you, you get 35 or so). So you see the business model: "cram as many engineers into an office as you can, and make money off of each one, just avoid the auditors." Work is so boring people literally sleep at their desks. Some people call it a dream job. It was like a prison for me. Also, people crammed into offices design for 1/3 of work force, bathrooms are always busy (hope you like warm toilet seats), parking is a circus.
