Pros
Lots of folks have worked here a long time. Interesting work and products. Decent 401k matching, HSA money and student loan payments can be matched in your 401k. Good work-life balance, but there are times when you might have to work bit of OT to get projects across the line. Good systems and processes. Training opportunities. Kind people. Extremely diverse! Lots of opportunity to move around groups and roles.
Cons
Pay is a big one. They do cuts about once a year and you can go years without a raise. Rank and File employees are rif'ed pretty often. For some reason, management is really focused on keeping people who they would probably be better letting go. There are some groups that are very old school b/c the same person has been running them for 20 years. Very HR run business, so be careful about what your manager promises you b/c HR may not agree. I struggled with the cultural ideas b/c they say one thing and do another. The group you are in can be the difference between a good experience and bad experience. Be careful if you are a star employee b/c a lot will get put on your plate. No snacks or any fun events. You work and that's about it.
