I was interviewed by them. Best process ever. Easy, straightforward, had options but I wasn't really interested in working for other people anyway. They let me code in ClojureScript for the snake game if memory serves. Also, this was many years ago when they initially started out so I am assuming they only got better.
I agree, I was one of their early people (they even met me on a holiday weekend at their offices across from the stadium as that was the only time I could fit in for their "long form" interview). Was best process I've ever been through.
My only critique, is that it seems a bit too front end oriented these days for someone like me who is basically a deep backend person. They did have long form infrastructure questions, but as I get asked to take their prototype tests every so often, it seems many of the new tests are just front end oriented (i.e. language types). I'm guessing this is because that's where the market has taken them.
