I applied through other source. The process took 1 day. I interviewed at RTX in Nov 2023
Interview
It was a casual interview with a senior GNC person. The interview went pretty well. There was a brief technical section where they asked about FFT, eigenvalues, and stability of LTI systems. It was not difficult just review what those things are and how to deal with them for linear systems.
Interview questions [1]
Question 1
How can you tell the stability of an LTI system from its eigenvalues?
