SpaceX Mechanical Design Engineer interview questions

Applied on company site, recruiter reached out via email to schedule phone screening interview a few days later. I submitted my availability to the recruiter and they confirmed a date and time for the call. The recruiter never called me. I followed up with a few emails to see if we needed to reschedule but I have been completely ghosted. Highly unprofessional and huge waste of time.

They asked mechanical fundamentals questions, Followed up with some questions regarding the resume. Asked why you applied for that position. Asked what university you attend and when you graduate, They asked if you are interviewing with other companies as well.
