Since the engineering team believes they are elite engineers working for Elon Musk, they want to know if you can answer the popular brain teaser questions you can find online from SpaceX or Tesla. It was unclear if they could have answered these questions on their own. Otherwise I got the job on vibes alone. Nothing on my resume indicated I was technically qualified or intellectually interested but still wound up getting offered a salary that considerably more than my manager’s, which seemed to upset him!
