McMaster-Carr Managing Tech Projects interview questions

I first had a pre-screen with a campus recruiter. The interview lasted about 30 minutes, behavioral with some case - relatively easy. I received a phone call 2 days later saying that they would fly me out to Chicago for a final round interview. It took pretty much all day (from 8 AM - 4 PM) that consisted of a tour, four 1 hour interviews, and an informal interview with 2 employees over lunch. Overall, I had a rather good experience and I am still waiting to hear back from them.
