Pros
Casual environment, unspoken and unofficial but useful work from home policy, all the hollow benefits everyone seems to like at trendy startups. Just be careful not to actually use the game room, as there are droves of folks waiting to tattle on you for not being at your desk every minute of the day, and plenty of managers ready to use that information against you. Oh wait this was supposed to be "pros". I did get a 1% raise, so that was cool.
Cons
Where to begin. At the risk of beating a horse that's already thoroughly stomped by other reviewers... Upper management. I've never seen so much backstabbing, idea theft, sniping, and disrepectful behavior at a company. I once witnessed the director of product management berating a product manager and asking him repeatedly "are you completely stupid? are you? are you stupid?" Never be naive enough to think your ideas matter. Unless you're in a certain clique, much like high school, the best and most useful ideas are dismissed out of hand. Except when they're stolen and used by a director or VP level to please the CEO. Departments have openly adversarial relationships, especially between "Product" and IT. Lots of blame and finger pointing, lots of excuse making. When I left the company, there was effectively an IT shadow organization under Product trying to work around IT. Weekend and overnight deployments galore. Building a new "enterprise" ecommerce platform that is SOA but undeployable without manual oversight and vast service dependencies speaks volumes about the "genius" crew - the ones who make decisions and get lots of hero-worship service. All in all, this place is like an episode of Silicon Valley. Hooli, without the talent or success. Don't waste your time.
