RTX Modeling and Simulation Engineer interview questions

I was invited to a hiring event that consisted of a plant tour, networking event, and interviews over a span of two days. The interview consisted of two other people and myself. It was relaxed and very straight forward. They wanted to learn your interests and skill sets as well as your personality. The questions were fair and balanced with some behavioural and some technical. All in all these people genuinely want to hire you and are seeing if you will be a good fit with their own respective team. I received an offer from them the following morning.

There was a phone interview with a couple questions on signal processing, physics, and software. These questions weren't that difficult, but they each had one right answer and were designed to test my hard-skills. After that, there were some more conceptual questions about general problem solving approaches. These were more open-ended and designed to test my ability to understand a problem and propose a solution. The phone call was ~30-45 min. After that, I was invited for an on-sight interview. This consisted of a meet & greet, a tour of the workplace, a networking event, and a sit-down 45 minute interview. The interview consisted of 4 parts: First, they told me about what my work would be like; Second, they asked me questions about my hard-skills, i.e. math and software; Third, they asked me about my good and bad experiences with team projects; Fourth, I asked them questions.
