Really enjoyed all my 1:1 interviews! Mostly technical questions. Some were a bit challenging, but nothing unbearable. Most questions were in fact pretty interesting to discuss. General engineering thermo-fluid. Some questions about fundamental rocket concepts. Really nothing too bad. I got challenged the most by a structures question, because I haven't dealt with structures for a while. I think a candidate who did well throughout all their undergrad/grad school, is strong in fundamentals, and has a reasonable background in propulsion (e.g. took propulsion classes and actually did well and feels comfortable about it) has good chances to prepare themselves and do well in an interview like this. At least from the technical perspective. Another side of it is this: It might be difficult to prepare for something like this overnight. The type of questions and the discussions that take place really require you to have a thorough and solid understanding of the important concepts in your field, which is smth you learn in school (or a good job, e.g. in R&D), and it takes you a good several years to build and solidify in your head.
Why SpaceX? This is the most important question since we require dedication.
How important is national defense?
Have you ever designed a more complicated component than the one you presented on?
How does temperature, pressure, and velocity change through a venturi?
HR asked about my experience and if I could describe examples of things I'd done that pertained to specific lines in the job description. The interview with the CTO was just me asking questions about the company and the position. I was never really asked any questions.
Director of Propulsion: Pretend I don't know anything about rockets and teach me about how they work.
