It is a sweat shop. Leadership expects you to be in the office until 8-9pm. It is a micro-managed where you are simply a cog in the wheel. The work environment reminds me of a Busch League recruiting consultancy.
I've seen many people in the Engineering and Recruiting department leave full time status w/ equity before their vesting cliff date, including myself. You know there are problems when the so called "sexiest" pre-ipo can't retain their top talent for more than 6-8 months.
