Avantages
9/80 schedule. Big company to move around on campus and at different locations world wide. Good work life balance depending on the program you are working, but in general its a typical work week. On site gym. The onsite cafe is so-so. It's not the best or best priced, but its convenient. People tend to be pretty nice. Nothing out of the ordinary with big corporations. You have the complainers that VPs and higher ups are too high paid, yada yada, and then you have the people who just get stuff done without complaining. In general it's a good place to work. Personal growth is definitely there if you are a go getter!
Inconvénients
The only major con I see is that its a slow paced environment if no major contracts have been won. Also with any Aerospace job, you might be stuck creating a bracket/widget for years without ever seeing one made. There in a transition phase right now which causes a little bit of disconcern.
