A pretty thorough process of the CTO getting to know you, performing a take home coding assessment followed by a peer review of the completed assessment. Next is an HR interview and then an interview with a senior level member of the team you'll be working in. The CTO is incredibly knowledgeable and enthusiastic about the company and its goals, and explains the entire interview process far better than I can. Expect to have no confusion about the process; they're very good about letting you know where you're at and what the next step is.
