Great benefits including pension, amazing health care. World class facilities and opportunities for global travel/experience. They pay very well.
Cons
Very stiff, hard to navigate politically. Very opaque and medieval ranking system. Work environment can be joyless, especially in certain organizations. Very demanding. Management leads by intimidation not inspiration.
Everything else. Benefits are lackluster, Flex Your Day policies are elusive. The company changes everything all the time so that a large portion of your time is spent finding new links to things on the portal, figuring out who to contact in various departments and in what country just to get a simple answer to a question. No one stays in the same role long enough to get good at their job. Morale is terrible.
