Pros
some good and smart people; employees generally happy to be there; excessive amounts of free candy and free soda (a huge perk, right? that'll put at least a few pounds on you!); people believe in the mission (to a surprising degree) and management and others involved in the overall operation of the company tried hard
Cons
Unfortunately I can't get into too many specifics. I'm pretty sure they hired at least a few Sr. Managers that probably knew their stuff well, but lacked the people skills necessary to be genuine respected by their employees (that's sort of important). I think they've probably gone as far as they can with their products, though their mobile apps seem to be popular. If I'm wrong, more power to them. A friend who was one of their engineers complained of constant wake up calls in the middle of the night. As he put it "the network needs serious help." It did seem like the IT people were frequently scrambling.
