The available SpaceX software engineer report describes a process built around showing how you work, not simply naming tools. It began with a recruiter conversation about background, motivation, availability, and compensation expectations, then moved to a timed take-home assessment that the candidate found difficult. Treat the assessment as an independent work sample: give yourself a time limit in practice and leave enough time to check that your solution is solid.
The final stage was a five-part onsite session. One component was a presentation to the prospective team on a past project. Prepare one project story that can withstand detailed follow-ups: explain the problem, your implementation choices, the tradeoffs you made, and why you chose them. The reported discussion also included a practical domain question about hydrostatic proofing, suggesting that role- or team-specific engineering context may enter the conversation alongside the project deep-dive.
The candidate characterized the environment as serious and detail-oriented, with emphasis on communicating technical work clearly to a team. Practice presenting your project aloud to an engineering audience, then ask a peer to probe the decisions behind it. Evidence is currently limited to one software-engineer account, so team and level may change the sequence or content.

The recruiter reached out about a month after I applied online, and I ended up scheduling a phone screen a few days later. It was a pretty standard 30-minute call, but it was very resume-heavy from the start. They asked me to walk through my background in detail, explain my most recent project, and talk through the technologies I had used before. There were also a few basic CS concept questions mixed in, plus the usual behavioral stuff like why I wanted SpaceX. The interviewer also asked me to describe a challenging thing I had worked on, so it felt like they were trying to gauge both depth and how I think about problems rather than just checking boxes.
What stood out most was the tone of the call. The questions themselves were not especially hard, but the interviewer came across as pretty condescending, which made the conversation feel more stressful than it needed to be. I didn’t get past the screen and received no offer. If you’re preparing, I’d make sure you can explain every line of your resume clearly, especially your latest project and the specific tools or technologies you used, and be ready for basic CS questions plus a straightforward “why SpaceX” answer.
Prep tip from this candidate
Be ready to walk through your most recent project and the technologies you used in detail, since the screen was heavily resume-focused. Also prepare a concise answer for why SpaceX and a few basic CS concept questions, because those came up in the 30-minute phone screen.

Synthesized from candidate reports. Individual experiences may vary.
One senior software engineer candidate reported an initial recruiter call covering their background, why they were interested in SpaceX, availability, and compensation expectations. Prepare a concise career narrative and a specific explanation of your interest in the role.
The candidate then completed a timed take-home assessment and described it as fairly difficult rather than a quick coding exercise. Candidates may benefit from practicing focused implementation work under time pressure and reviewing their solution before submission.
The reported final stage was a five-part onsite session, including a technical presentation to the prospective team on a previous project. The candidate was asked to explain implementation choices and tradeoffs; practical domain questions, including hydrostatic proofing, also came up.
