Pros
Competitive salary, one of the best benefits, high 401k matching, health insurance, in-house health center, snacks from pantries, seasonal treats, free soup, smart and nice coworkers, flat hierarchy within the team -- all team members work closely together. One of the most stable jobs you can find to afford your family. Company subsidized team dinner/lunches. Provides dinner at the office if you stay until 8pm. Some groups are using more open source technologies which wasn't the case in the past. Great work-life balance. High internal mobility.
Cons
Not much vision for career advancement other than the raise and compensation. Upper management is pretty much not moving at all. Can notice a lot of politics in the upper management. Very corporate. Very financy atmosphere -- feels uptight overall, so R&D makes an extra effort to make it chill. For the engineers who are actually interested in finance (which isn't the case for many people.. but for these special kind), this is THE place to work at.. otherwise.. just not so much motivating or fun.
