People I interviewed with were pleasant, 1 HR phone interview, 1 phone interview with an Engineer. Engineering interview was nothing but questions on engineering equations and reciting them from memory (not actually on engineering principles or fundamentals) , reciting the exact numbers of material properties, then being asked what those are in English units if you work in SI normally, density, yield stress, ultimate tensile. (Oddly 0 questions on aerospace structures, presure vessels, FE theory or anything of what is in the job description) It is very hard if you work for a global company that sources materials from multiple standards (some standards don't specify certain criteria )and has to jump across equivelents all the time as all those numbers aren't memorized. But it is fair questioning if that type of memorization is required for the roll. Never had an interview so based on memorization over the phone before honestly just write up a cheat sheet and get ready to read off. You are honestly set up better for this interview if you are fresh out of college with a FE book in hand than having the 8 years of Fea experience they ask for It was nice that they tell you where you fell short on the interview and let you know with a phone call instead of leaving you hanging.
