Two mostly technical interviews that started with some outlining of my experience and some basic structures questions + propulsion questions. Asked about pressure vessels and where they fail first + cantilever beams in first interview. Second interview asked about pressure vessels and combustion chambers/how I'd go about designing one; Guy got excited when I talked about using hand calcs.

Email message was received about interview opportunity. Two interviews of around thirty minutes in length. Questions involved experience in projects, and additional technical questions. First interview was more of a screening, second was more in depth on experiences.
