Pros
1. Some of the engineers ( mostly junior to mid level) are very talented with prior experience in big investment banks, so you can learn a lot from them.
2. Free food, snacks and drinks.
3. Moderate work life balance - depends mostly on the team.
4. For good engineers in India, they are easiest way to get the H1B. As soon as you come here, start preparing and switch.
Cons
Ambush firing are more common than features addition to the products. There is a policy of total non-disclosure, so its very difficult to figure out the road-map of the products or to gauge the performance of the company. Nobody clearly knows whether the company is doing good or bad. The main product was developed 7 years back and currently the major work is to fix the bugs and maintain that crappy codebase. The senior people, barring one or two, are spineless people somehow holding their jobs. Being in such an important business field, I see no seriousness in the attitude of product managers. Most of the bugs are reported by users in production even though there is full QA cycle to test the products. I think I just depreciated my career and personal life by joining this unethical, directionless and pathetic company.
