Pros
The company has had a ton of success over the past 2 years. It a very exciting place to work and the salary, stock, benefits are great. There is a new focus on science and the company is throwing resources at R&D. If you're in the right group, you will see a lot of flexibility in work arrangements (WFH, telecommuting, etc)
Cons
Management is, for the most part, awful. There is constant infighting, finger pointing, and political jockeying. Also, the bureaucracy is both crushing and worthless. A good 30% of the staff are here only because they are too vested in the stock plan (golden handcuffs). If you are applying, have a long timeframe. HR is slow and borderline useless. Expect rude comments, arrogance, and lack of communication and follow-through. In my experience, I have seen 3-6 months from first interview to offer. You will also get low balled in salary and title.
