Pros
As a good patriotic company, Northrop Grumman will cover your pay for jury duty and they pay 6 weeks salary if you have a child (for mother and father). My experience is that Northrop Grumman tries to produce high quality work rather than just enough to get a contract and move on. This results in a lot of repeat business, so even as a contractor, you can get very long term employment with the same department. My immediate management has done a good job at taking care of me and they are good at minimizing office politics. All in all, I found working for Northrop Grumman to be a positive experience.
Cons
I feel that my salary is a little week. Also, as I work on site for the federal government, I am subject to the high levels of insanity that come with the job. Often I feel like one of the office clerks in the movie 'Brazil', but this is not a direct result of working for Northrop Grumman, but rather working for the feds.
