Ventajas
Prestige is the first thing that came to mind when I first got news of the job offer. It's primarily an aerospace defense contractor that has its fingers in so many other disciplines that a lack of projects is hardly an issue. It is a highly respected company that actively employs professional and ethical practices in all aspects of its operations. With a current backlog in the billions of dollars (2009), this company has managed to be impervious to even the current market state. All my coworkers (myself included) have not broken a sweat knowing we have solid job stability in the engaging programs we're in.
Desventajas
A downside to working at this company, as well as basically every other corporate job, are the mandatory 40 hour work weeks. Of course you have to put your time in and assure the company they're getting what they're paying for, but maybe I'm just a fan of "so long as the work gets done". Besides that, I have no other major complaints.
