Recruiter reached out. Initial call going over resume and gauging passion working for SpaceX. Job description clearly states as requirement able to stay longer hours and work weekends. Followed by technical interview that was an online coding session. Question could have been more clearly posed and written out.
Very unpleasant, interviewer looked distracted and cut me off when I couldn't answer the question in set time. Ended interview early very rudely. I hope that not all interviews at this company are like this.
