Pros
Competitive pay in the local area, LOTS of smart people. There are good places w/in the company, but it totally depends on whom you get as a manager as to whether or not you will be successful.
Cons
managers whose motto is "what have you done for me lately", a management team that thrives on fear & intimidation. I was in a group where both my direct manager and the director were arrogant and headstrong, and it made for some very unpleasant times. My manager expected inordinate amounts of time from me, and not that I'm unwilling to give it for a position I love, but for someone who constantly terrorizes and berates you, is it really worth it? I complained to HR about his behavior, and was told my complaints were unfounded. I did some investigating on my own and found that he had been demoted and moved out of a group after mistreating a number of employees.. and then 3 years later, he's up to his same tricks in a different department. If you are thinking of working here, be VERY CAREFUL and ask to talk to former group members to see if you can get the real scoop on your potential new boss.
