The interview was better than most interviews I have participated in. The actual engineers ran the interview with an HR representative present. They asked questions that were relevant to the job regarding experience with CAD software and completed coursework. They did not ask any of those ridiculous behavioral questions. I was asked to interpret a construction drawing and explain what I saw. I was also shown other drawings relating to mineral and ore processing as examples of what I would be working on. If you are applying to be an intern and have CAD experience, bring an example of your work (school project, etc.) if possible. Overall the interview was relaxed and I had a good idea of what the company did by the end.
