Pros
Interesting technology. Talented peers. Compensation is okay. Company appears to have a good product and vision for the future.
Cons
Where to start... extremely high expectations on performance coupled with expected use of personal time to perform research and other tasks. Lack of leadership within development teams to push back on management and promote good practices within teams. Aggressive deadlines which lead to technical debt in the code base and no interest from management in refactoring or any other work which does not lead to feature development. They say that they're agile, but only the parts that management likes. Architecture team is completely separated from the development teams so there is no real effort to improve designs. Extremely political atmosphere at the management level to the point where teams within the company can not effectively work with each other. 2 (now 3) week vacation policy but it is mandatory to use your PTO between christmas and new years, so you lose 3-4 days automatically. There is a lot of domain knowledge that experienced team members have acquired over time, but you are expected to know on day one. Extremely stressful.
