Process
The process started with an internal recruiter reaching out to get a baseline of experience.
I next spoke to a member of the team for 30 minutes and was asked some standard structural engineering questions.
After that, I made it to the second phone interview where I met with two members of the team for 30 minutes and was asked some pretty technical questions.
I didn't come up with the right answer, so I did not make it to the final round.
Questions
How do you size a rotary bearing?
You have two pressure vessels. One of them is tested in a vacuum, and it fails at 4 ksi. The other, tested in STP, fails at 4.5 ksi. How do you account for that 500 psi difference in performance?
How do you account for thermal expansion in a design?
