There were multiple rounds in their interview process that consisted of more general HR interviews just confirming qualifications, as well as a technical interview carried out by an engineer. That is when technical questions get asked.
Interview questions [1]
Question 1
They asked about simple fluid dynamics problems that focused on hydrostatics, pressure differentials, and a basic understanding of the assumptions made for fluids
I interviewed at Relativity Space (Stennis Space Center, MS)
Interview
Asked me to talk about any one of my technical projects on my resume and then asked difficult follow up questions about it. You need to have all your basic physics down pat, because I forgot some of the basics and it made the interview very difficult. They also asked two technical questions unrelated to the project.

Question 1
How can I found out how long it will take for an entire pot of water to boil?
I applied online. The process took 2 weeks. I interviewed at Relativity Space in Sep 2025
Interview
Applied online and got an email for an interview a couple of days later. When I joined the interview session via Teams, it went straight to the questions, not even a “how are you doing” kind of thing. The whole experience felt very rushed, like I was talking to a robot. It was clear that the interviewer did not read my résumé at all and only cared about the technical questions. The technical questions were quite difficult—studying the basics was not enough. Overall, it was a really negative experience. I would have liked to talk about some of my experience and why I think I’m a good candidate, rather than just solve absurd technical problems. Not conversational at all.

Question 1
There is a sealed bucket with water and air inside of it. How does the air pressure change as water leaves the bucket? How does temperature change? Show using thermo. What if the system is insulated?
