Pros
Fantastic people. I mean really: competent dedicated and they listen. That's a big deal, the listening. Everyone is passionate about the work, and they express that by living the way the site is written, thoroughly, and happily. Great benefits, good pay, most excellent kitchen with twice weekly Fresh Direct deliveries. One of the biggest things is the no vacation policy. Take as much time as you need, just get the work done and let people know how to reach you if you are gone for awhile. No clock watching etc. Just get the work done, be great at it and be happy. For someone like me who throws himself into what he does and isn't just looking for a paycheck, this is fantastic. The flexibility also comes in handy when you have a family. Also they want you to define what looks like a successful tour of duty there, which is a refreshingly honest take on work mobility. For someone who thrives on accountability, this place is an awesome place to work.
Cons
Too many Van Damme gifs on Slack? Seriously though, its a startup ( well, kinda, they've been around a few years) so things are not as polished or structured, so someone who needs that in their work life may not like that. For people who want to be judged on measurable results, and are happy to define how they do that, it rocks. They are very interested in you being happy and healthy, as defined by you. So that could seem a bit intrusive, but when you look at the evidence they have that shows happier employees are more productive, it makes sense. But if you are the type who wants to lock themselves in a cubicle and not have anyone talk to you, maybe not the place for you. Ok, no 401k yet (they are working on it) that would be good.
