Very open ended questions and just asked about work experience. Interview with 2 hiring managers. One time interview only to get an offer. Heard back 1-2 months later. Not much more to say other than that.

I interviewed with 3 mechanical engineers. The job posting was incredibly vague and it was clear after about 30 minutes that my experience was in a different engineering subject than they were looking for. Got a facility tour at the end. The entire process from initial application to this point was cumbersome, as there were a couple of months in between each step.
