The interview process was what I expected other processes to be like. They started with a phone screen, followed by a 3 hour onsite interview. Talked to the CEO, CTO, Director of Engineering and a company advisor. I requested to speak to an investor to understand the value proposition a bit more. Then finally an offer. Response times between events were usually 1-3 days, so they were responsive and ultimately they gave me a great offer which I was happy to accept.
