30 minute meeting with CEO where it was mostly general questions about my background and an overview of the company. The second interview was a 90 minute technical interview with the CTO. My first technical interview, and I'd say they were definitely doable tasks for someone with a comp-sci background (not me) and/or someone who studies for these things as I think they are pretty common interview tasks. Both the CEO and CTO were incredibly kind and thoughtful during the whole process. I especially appreciated the CTO's patience and encouragement as I was nervous (which affected my ability to do much of anything).
