Desventajas
Private company, so no stocks. Health insurance co-pay could be lower. Extremely limited tele-commuting policy. Can feel bureaucratic at times. Traditionally hired only engineers and only recently started hiring computer science grads, which means that some of the older code is not coded up as well as it could have.
