It can vary a lot from group to group, but in general, wonderful place with wonderful people and lots of interesting work going on. Excellent benefits and lots of flexibility to explore different projects.
Cons
Little opportunity for advancement in terms of rank and compensation once you reach technical staff. Additionally (again varies from group to group) expectations of what a staff member does can be unclear and there can be a light sink-or-swim nature to the work, again depending on the group you're in.
