The process took 2 days. I interviewed at Koch (Wichita, KS) in Apr 2015
Interview
The process was very informal in my opinion. First there was a "get to know you" dinner, and then the actual interview was the next day. The day of the interview, I had four, thirty minute interviews, mostly asking about my background and other behavioral questions. Just learn "Why Koch" and you should be fine.
