3 rounds of interviews: Began with recruiter phone call to see if my resume met qualifications. Second interview is with a "manager" or lead on electrical team to further go over resume and get more insight on your technical experience. Third round is supposed to be 4 interviews on-site taking up 4 hours of your day and focuses on technical skills. I only went up to the second round with a "manager" who was clearly not experienced as a manager and clearly seemed like someone who has not worked in defense before. He did not introduce himself, asked very interrogative questions about my work to try get as much detail as possible (I work in defense on classified/proprietary info so digging for information like that is a big red flag), and did not ask any behavioral questions that a manager normally would. He seemed like a competent and intelligent engineer but clearly not used to defense or a managerial role. Additionally, although they listed a general role with general requirements, they were specifically looking for someone specialized in batteries, HV systems, and PCB design for this particular project. They should have listed their opening as a battery engineer.
