Three fundamental mechanical engineering problems that consist of statics, strength of materials, and fluid dynamics. They do not mess around with these interviews so you definitely want to be at your A game. Highly competitive in my opinion. Interviewer also mistook the interview day and still made me wait a while, little bit ignorant of my time.

I met with some Key Tech Engineers at an online campus career fair, and had a technical interview a couple weeks later. Didn't talk about my projects or experiences, just wanted to see my technical ability. Did three basic conceptual questions on force balancing, bolt stress, and fluids. They really want to see conceptual understanding, so problems are simple enough to be done without calculators.
