Pros
Generally pleasant atmosphere, nice people, reasonably powerful equipment takes some of the tedium out of development. Overall the company has a good vibe and I found it enjoyable 80% of the time. Plenty of latitude to do your own thing and own your space.
Cons
Plenty of latitude is mostly due to management apathy and inaction. Horrendous aging codebase shows signs of prolonged hacking and neglect. Senior researchers tend to throw their weight around and outright blockade development they don't agree with. Most other staff are frantically bugfixing for the researchers who avoid code reviews entirely. Your career can easily be stifled falling into the servitude of research staff with endless menial maintenance. This process leads to a revolving door of staff with heavy attrition. Try here. If you get lucky you can get something done but if you experience misconduct then prepare yourself to exit promptly. Expect no help.
