Avantages
Good steady pay check. If you network correctly you can find some very technically interesting cutting edge programs. the benefits are good. you get to work a 9/80 schedule (every other friday off). you get three weeks of vacation, flex time and you can work on your off days to build up to two weeks of additional vacation time. They're also ok with you working from home from time to time. Very accommodating as employers go.
Inconvénients
Red tape and excessive process. If you don't network properly you can can easily get pigeon holed in a boring uncreative job. You can spend way too much time doing mind numbing documentation because your following some arcane directive that wasn't originally crafted with your project in mind but which got blindly applied to all programs across the company
