Pros: Nice building, nice fish, free snacks, good benefits, socially conscious, stable job.

Cons: There are those that love it, and I can only speak from my own experience: what you find will vary greatly from team to team. What I found is absolutely no career path or advancement potential of any kind for technical people. You are a "programmer bee," and that's the extent of what the company wants and expects from you. Much of the work is tedious and menial. There's a fanatical dedication to proprietary tools and methods (which, as an experienced senior hire, I really wasn't impressed by), no project management, and poor planning. It's a stifling, oppressive place that cripples all their best, most creative people. R&D is a massive sweatshop that relies on a constant stream of incoming H1Bs and fresh college grads they can get to before they learn anything that might make them attractive to another company. All in all, I'd say that if you're an experienced programmer with skills in legacy systems, or a recent college grad that can't find work, or you need the stability and benefits to support your family, then it might be worth it.

Pros: Have a chance to code financial applications. Big company opportunity to learn.

Cons: legacy technology, company unique technology

Pros: A lot of junk food.

Cons: People treated like slaves.
