Interview started with a phone call/coffee chat with HR, then proceeded to interview with the CTO the following week. In the interview with the CTO, the CTO asked some off questions for a technical interview, and rudely cut the interview short when he did not like some of the answers (I had different opinions than him on certain things which apparently is a dealbreaker with this CTO). I asked many questions of the interviewers and doubled the duration of the interview in doing so, although I am sure they wish I just stopped so they could end the call. Ultimately, the most insulting thing about this process was that they completely ghosted me after the interview.
