I have been working at Northrop Grumman full-time
Extremely positive work environment. Management is extremely helpful while staying mostly hands-off after initial training. The exceptional body of talent across many different disciplines and... variety of programs lend to going home each day smarter than when you showed up. Lots of opportunities to expand your skillset, and coworkers who will make you feel truly appreciated.
Despite advertising competitive compensation, pay bands are antiquated (at least as of Jul'22). Hopefully HR catches up with the times.
