SpaceX Manufacturing Engineer interview questions

4 Interview rounds, with 1 phone pre-screen followed by 2 phone interviews (Technical first then Behavioral) and a 5 hour onsite interview consisting of a brief tour of the main production floor, then a 30 minute presentation(Blocked out to 60 mins for questions). Afterwards I had 6 back to back one-on-one interviews with various members of the team with questions ranging from actual(how would you solve a problem with this part) to theoretical(how does an engine work?) to more about myself(Why are you the best fit for this job?). After this I was given a tour of the separate facility where I would work before being escorted back to the front desk and leaving. Was told I would receive a decision the week after but got an automated email on Saturday saying I did not get the job. Was not able to get any kind of response from the recruiter afterwards concerning any feedback which was pretty disappointing considering all the effort I put into everything prior.

4 total rounds (3 phone, 1 onsite). 1st round was recruiter screening, 2nd round technical with team member, 3rd round behavioral with team member, and 4th round was onsite. Onsite interview included a tour of manufacturing floor, followed by my delivery of a 25min presentation on a technical project of my choice from previous experience. This is followed by six 1-on-1s with the team and lunch. I made it through 2/6 of the 1-on-1s before I was escorted out. These interviews varied from technical to behavioral. Team was very polite and easy to talk to, Manager took time to give me detailed feedback and specifics on why they would not be extending an offer. Very constructive criticism and strongly encouraged to reapply after gaining more experience. Appreciated the detailed feedback and encouragement from the team. Based on casual conversations and lunch with members of the team can tell the atmosphere is that of people taking pride in their work and maintaining high standards for one another. Overall the experience was fun and enlightening. Didnt see a lot of "tired" or "depressed" faces. Regular people working hard, living and breathing space.
