SpaceX Build Engineer interview questions

Scheduled an interview and HR messaged me and cancelled 1 minute before the interview starts because the position is filled. It seems there is a lack of communication between hiring manager and HR.

Initial Recruiter call. Made it sound like they needed the position filled quick and after a very straight forward quick conversation he mentioned I would hear back by EOD to schedule the next interview. Ghosted after that, tried to reach out a couple times but nothing.
