It was a casual conversation with the CTO. We talked over Skype and he asked me various questions about myself and my past experiences. Then he allowed me to answer any questions I had about the job. It took about 20 minutes and it was just a nice interview. It feels strange to add a question because nothing asked was super technical. It had to be rushed due to meeting a deadline on hiring, so it was very unplanned and a lot less involved than their usual interview process.
