I applied through my universities career website, and was invited to interview within 2 weeks from the application deadline. The interview was informal and held at the career center for my university. I was interviewed by a recruiter and a mining engineer from a nearby location, but was interviewed mostly by the recruiter. The interview lasted about 45 minutes and consisted of 2/3 of the time answering interview questions, and 1/3 of the time them talking about the coop position and life at the mine. All behavioral questions, no technical questions, with a lot of focus being placed on how you would handle certain situations or conflicts, as well as safety at the job site. I was told I would get a response within 2 weeks, and that if accepted would have to take a pre-employment drug test.
