SpaceX Sr Software Engineer interview questions

They moved quick and it was a streamlined interview process. One screen phone call and two video calls. There was an opportunity to send a sample of past presentations I gave and it was forwarded, and well received. The hiring manager and HR were fine. This place is 150% hype with a regular level of benefits and pay for this area. The third interviewer was fake, bias, and not professional at all. All interviews went well. They rejected me two days later. They only want foreigners for those higher positions and California is the land of foreigners. The feedback was illogical and ridiculous. Essentially, it said we need a person to setup and manage a software (which I have 15 years of experience in), but we don't have a position open for that software and we don't have a need. The position I just interviewed for is an open position involving that software they complained about.
