I applied through college or university. The process took 3 weeks. I interviewed at Koch (Norman, OK) in Sep 2016
Interview
The interview was 30 minutes total. 25 minutes of answering questions with the last five minutes for questions you can ask. The questions were 100% behavioral. They make an effort to get you comfortable. It was an all around good experience.
