SpaceX Intern interview questions

first interview was two behavioral questions and then i was asked a ton of technical questions about solid mechanics and statics (think forces on cantilever beam). the interviewer was pretty nice but i flopped on all the technical questions (been a few years since i took that class) and i asked a follow up question about next steps and he said "ah yeah i can send that over to you" but it really seemed like he was not interested at all and i did not get the role
