Ventajas
The work itself can be rewarding and challenging for engineers. Onboarding right from interview process to relocation is very well executed.
Desventajas
The matrix organization that is touted as the template is not followed here. There is no parallel hierarchy of program manager vs functional manager, essentially the functional manager is simply 3 managerial levels above your program manager. There are many semi-skilled managers at the lower levels that have poor leadership qualities. They will easily castigate technical excellence and producing quality work with a bullying type attitude. It is a big company, but it can feel like there is nothing beyond the immediate manager, while any recourse requires reporting to HR/Ethics which requires documented paper trail of retaliation, not a luxury available to much of the classified work that's done here. Level 1 and level 2 hires straight out of college have the ability to rotate programs and get out of nasty situations this way, but I would not recommend this company for Level 3-5. You need to know how to play politics and stay in the good books with your work to make your immediate managers look great. Not a quality readily available to introvert nerdy types.
