I applied through college or university. The process took 3 weeks. I interviewed at SpaceX (Hawthorne, CA) in Nov 2023
Interview
First round was a 30 minute call. First half was behavioral, asking about previous experience both professionally and org-wise, second half was technical, asking questions about C++ structure and memory management.
Second round is an open note OA for one problem. I was given 24 hours from start, but question I received was luckily easy compared to others.
Third round is completing a word doc describing your education status and then your four largest accomplishments in bullet-point form (1-2 sentences for each accomplishment).

Question 1
How would you direct C to put data in a stack versus on a heap?
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?
