Blue Origin interview questions

Submitted online application, got a call from HR after a week, and set up phone interview with an engineer for two days later. I rushed this for reason I mention below. Interview itself took an hour or a little little, was scheduled for 75min, with access to computer for code sharing platform.

I have to say the people are fantastic. Every one of them was personable and super sharp. The interview process was like waking up after a long sleep in roles that limit engineers to small scopes of responsibility. It was refreshing to see a place that requires both design and analysis. It started off with a phone screening with a recruiter, followed by an on-site. The first on-site was a one on one chat with the hiring manager, who asked work history and discipline-specific questions peppered with technical questions. My brief interaction was a positive one. Once I got word that I would be moving forward in the process; I was set up with a full interview loop. The full loop included a presentation to those who would later be interviewing me one on one regarding my work history, followed by some Q&A. After the group presentation; I sat down with each person and we discussed relevant technical knowledge. I'm going to say it really showed me how much the silo I work in now has degraded my memory of some basic equations. You can bet I went back and brushed up after the interview on everything I didn't remember. Included in the questions were problems to solve that gauged my knowledge and (I believe) my approach to problem solving. Everything from free body diagrams, to beam loading, to schematics and material properties. I'm going to call it difficult, because relative to every other interview I've had for an engineering role; this one was the hardest. If you haven't lost your knowledge material properties and equations to the sands of time; it should help a lot. It comes back quickly, but if you're home when it does; that won't help you.
