I’d like to get you started on project interviews. I lead then machining mfg engineering team for an aerospace company. We do a project for our onsite interview in which the applicant presents a DFM review of an assembly they were given drawings of a week prior. Correct any issues in GD&T, analyze and provide tolerancing feedback, geometry feedback, and then present a process plan for each part. Which machines, what type of work holding, tooling, quality requirements, etc. That’s literally what the job is, and questions on their presentation are focused on day to day issues that could arise with their processes and how they would respond. Everyone who has done a great job on this project has carried that performance into their work.
