The hiring manager got back to me three days after I applied on their website. There were two 20-minute initial phone calls. My next step was a Skype meeting with the hiring manager. I think this one lasted 20 minutes. Two engineers interviewed me back-to-back a week later. During my interview, the first engineer gave me five minutes to solve a simple SQL problem, while the other engineer asked me a bunch of questions about programming. In the final interview, I talked to one of the managing directors. It lasted 30 minutes and was very casual.
