I interviewed in St. Genevieve Missouri for a co-op for the summer and winter of 2018. It might say it was in St. Louis on glassdoor but it was not, St. Genevieve was not on the list of cities to pick. Every interview I had there was a group interview and they asked a lot of weird questions that did not pertain to the job. I interview with one other process engineer and with another guy who was a mechanical engineer. They gave us a full tour of the facility and how each part works. I was there from about 8am-2pm. All the guys were nice and laid back. They also took us out to eat. I did not end up getting the co-op.
