Hyperloop One Software Engineering Manager interview questions

My interview was a strange one. It was a tour that ended with me having a beer with the head of engineering, Josh Giegel. At the time, I had no idea who he was, only that the person giving me the tour had to take care of something and I now had someone new to meet and talk to. We discussed software needs for Hyperloop, how I thought a software team should be grown, and my overall goals. To this day, I do not really know if it was an interview "set up" or a lucky random happenstance. At the end of the discussion, Josh gave me his card and said that I should let him know if I can figure out a way that I could help out Hyperloop. After 3 weeks of thinking about it, I drafted a "treatise on building a software team" and a month later, I started at Hyperloop.
