Pros
Lots of food. They serve a ton of snacks and meal options. Great perks for a startup, they are competitive with Zynga and Facebook on this. Short work hours, everyone leaves at 4 pm on Fridays for Tea Time. Low expectations for team members. easy to get promoted to Tech Lead. If you are coming from Google you will feel like a genius. Extremely social company, very friendly leadership. High salaries and restricted stock.
Cons
Very frustrating to be a Software Engineer coming from an environment like Google. Unusually high turnover for a startup tech company, particularly among senior management and high performers. You never know when someone is about to leave -- and often you have no idea why. Very secretive. I have no idea how the company is doing in terms of finances. Most big news I read about in Tech Crunch. Engineering reputation is poor. It's getting better, but hiring is difficult.
