Good process and many technical questions. The questions are open-ended and up to you to show how you work through the process. There are also questions relating to explaining some of your projects.
Interview questions [1]
Question 1
Cantilever beam, where is the most stress? and what happens when you change the shape of the beam profile?
I applied online. I interviewed at SpaceX (Brownsville, TX)
Interview
Asked technical questions regarding basic college engineering fundamentals, asked engineering portfolio questions regarding previous internship and project experiences, and asked hypotheticals based on what areas were owned on those projects.
First was with a lead engineer (technical), then with a recruiter (behavioral), then with another lead engineer (technical), future would have been on site. It was a very accelerated timeline and fast process.
Multiple rounds of interviews ending with an all day onsite interview. Asked questions about background, classic textbook problems, and coworker interactions. Very technical and difficult. Lots of time spent trying to understand your thought process
