Pros
10% retirement contribution whether you contribute or not; good health, dental, vision insurance; ample vacation time; decent pay; no funding worries; food service (subsidized food prices, free coffee/tea and fruit); free gym & exercise classes; abundant other perks (at least for now).
Cons
Isolated location; no career advancement; "diverse" but there are blatant divisions (predom. Latino cleaning/kitchen staff, Black/African security, Asians/Whites in research or admin positions). The benefits may keep you here but ultimately, this is where careers come to stagnate. Make sure that you're okay with the position you're offered because you'll be doing the same thing until you leave. If you're lucky, you may get a promotion. However, promotions are not based on skill/knowledge, they're based entirely on how buddy-buddy you are with your manager.
