Pros
Colleagues are friendly and smart. Opportunity to work on the latest technologies. Good stepping stone for gaining experience to join a larger employer later. Flexible working hours.
Cons
Upper management takes advantage of staff. When they go IPO at a low price, they ask you to sign a voluntary paper to convert your higher price options to lower exercising price options, but your options vesting year resets to the current year. That means the number of options you can vest is the same as a new hire, even after working here for many years. Why not just keep the same vesting date? Why take back the options already vested to you? The bonus given to staff is also a joke. It's just a small bonus, yet they ask you to agree that you must stay here for the next year else they take back the amount from you. C'mon, If people want to quit, no one cares about such a tiny amount anyway. Managers commit to unrealistic timeline to you without discussing with you first. When you can't make the deadline, they blame you. There is also no appreciation from management even if you work very hard to meet the impossible deadline.
