I applied through college or university. The process took 1+ week. I interviewed at SpaceX in Sep 2021
Interview
First round was fine, standard phone screening going over aspects of my resume. Second round was very unexpected. After first round I was told to expect a technical dive into my resume/past experiences, but instead was just hammered with OS/Networking questions. Granted I should have known these topics, I had never studied them before and nowhere in my resume did I indicate I would have known anything about these topics. I do appreciate them extending an interview, but overall it was a colossal waste of time.
Applied online has two round. First being an phone call with recruiter and the second being online with a team of engineer asked about my previous experience and then had a short coding leetcode style question

Explain a recent debugging problem and how you solved it.
Basic questions about python vs c++, am I authorized to work in the US, stack vs heap, projects and my experience mentioned in my resume, quick introduction about myself and why i wish to work at spacex.
Recruiter screens usually hit: time/space complexity of common operations, why O(log n) beats O(n), array vs hash map vs linked list tradeoffs, and Big-O of sorting. Want me to drill you on these?
