Too Long; Didn't Read
There are never two identical engineering job interviews, but there are some common common hiring practices. Hiring people, not skillsets, is hiring people who will stay at the company for years and work productively. Engineering is constantly changing - new technologies replace the outdated ones, regulations (especially in the case of aerospace engineering) get broader. That’s why adaptability is a must-have quality of a modern-day engineer. Take your time if you need it, not to “play cool” once you’ve made up your mind, let the candidate know.
