First got asked what is a problem I stay up all night thinking about. Then I got asked if a hollow rod and a solid rod of the had same height and material which would bend easier. Then finally I got asked about the behavior of a drone being launched out of a car at 70mph. I had not brushed up properly on my physics so I wasn’t really prepared for it I expected it to cover more manufacturing oriented things. But all in all a really insightful and inspiring experience also showed me gaps in my thought process and knowledge and will try again hopefully sometime later. Note: lot of former Tesla guys at this startup so prepare like one of those types of interviews.
