I went to the hiring day hosted by BEI, and I believe anyone who shows up gets an interview that day. The 1st one was behavioral, the recruiter manager just asked me about my experience that I listed on my resume. Waited a few days, and the second interview was with the hiring manager of the stress team. We went into further details regarding my projects. In the end, you have to complete a technical test on the fundamentals, beam bending diagram, shear force diagram, etc.
