Two video chat interviews, followed by an person interview. Chat interviews were more technical, in person interview was more personal. CEO asked me questions I considered pretty inappropriate and possibly illegal (He asked me if I have kids or if I plan on having kids in the near future, trying to determine if I would be willing to work long hours). The developer who interviewed me was nice enough, but the CEO removed any chance I had of continuing with the process. Very slow turn around time (promising to respond the next day, then not responding for several weeks).

Informal interview followed by a code challenge then an on site interview. Overall it was a very casual process. No follow up after. Everyone was nice and the office was cool though.
