I applied online. The process took 2 weeks. I interviewed at SpaceX (Hawthorne, CA) in Oct 2025
Interview
Recruiter honestly stayed on top of it. Heard back extremely quickly after each interview. Process was:
Recruiter phone screen (didn't have any trivia questions, just ensuring you're a good fit) -> Take-home assessment (this is where I failed, but 4 hours to complete a take-home assessment) -> 1-on-1 Codility with a SWE on the team -> onsite.

I applied online. In a day or two, a recruiter reached out to me asking for availability. I filled out the form but never heard back. So not sure what happened there.
Recruiter Screen->OA->Technical Screen->Onsite->Behavioral. The OA was a mix of linear algebra and a practical problem, but the rest of the rounds were not that coding intense. In the technical screen, be prepared for very specific domain questions.
