Vantaggi
Fast pace, learn skills that are valued by other tech companies. Pay is good if the stock value keeps going up and you got the stocks few years ago.
Svantaggi
Location. Hard to commute into Seattle downtown or SLU. SLU has no proper public transit that would not require changing of bus. Parking is limited and you have to pay 150 dollars per month for parking. That's a lot. Management strongly discourages working from home even though that would help solve the commute problem or at least make it less miserable. Managers also want everyone to work regular hours so that you commute during the worst rush hour. No flexible hours. 401k match almost non-existent. "Holiday" season is not something to look forward. You will be working like crazy and on call.
