I echo some of other interviewees experience that the technical interviewer team is inexperienced and arrogant. I applied for Fluids system engineer job and from my resume it was clear that my fluid analysis background was the main strength. However, at the end of interview, most of questions were focused on heat transfer/thermodynamics which I haven't dealt for many years. Obviously, I couldn't answer those questions satisfactory but given minimum time I am able to solve related challenges if they are part of any project. Also, in one case, one of the interviewers asked me about the meaning of Nusselt number and I said I didn't remember it since I used it many years ago. He joking laughed and called his colleague saying we have somebody who doesn't know the meaning of Nusselt number and asked him to come and explain it to me! I felt humiliated and surprised....Does it represent the overall culture in Blue Origin? In another case, I was asked to provide an equation which I used for designing an air track 10 years ago... of course, I didn't remember it but I was able to provide the general approach I used...Also, I offered to provide the related design document if interested. I wasn't sure if I am being interviewed for my skill/talents or for my memory! No wonder they are behind SpaceX for many years....
