I was in the interview for about 1.5 hours. The interviewers were remote. I scheduled a screening call with a recruiter. She presented my information to the hiring teams. I got an invitation to meet with two team hiring managers.

Met with representatives at career fair who passed my information along. Met with representative a week later for an introductory interview. Nothing too difficult or technical, merely evaluating how you present your achievements alongside your resume. This was followed by an in-office interview. I spoke with the head of that office's structural department for a half hour, mainly about what the job would entail and what kind of person I am. This was followed by four more half hour interviews with employees of descending seniority within the structural department. Very laid back, informative conversations. Only once was I asked to yet my knowledge of structural engineering. Very nice, honest employees. Every single one said the half the work was engineering, half the work was regulatory paperwork. Good experience. 2-3 hours long though
