Relativity Space Structural Design Engineer interview questions

They do not ask you typical questions like, "why did you apply for this company?", "Tell me about yourself.", "What makes you think a good fit for this role?". After a very short introduction of the interviewer (engineer), they move straight to the hypothetical technical questions. If you have a D: 7.5ft, H: 100ft launch vehicle standing on the launch pad to test if the launch pad can hold up the vehicle when the engine is fired, how would you test? What are the things that you need to consider?
