I applied through college or university. I interviewed at Koch (Wichita, KS) in Apr 2017
Interview
They focus on values and integrity more than knowledge. They want to see what kind of person you are. Cocky and conceited will not last no matter what your talent
The overall interview process was smooth, well-structured, and professionally managed. The interviewers created a comfortable environment and maintained clear communication throughout each stage. The discussion was primarily focused on technical concepts, practical problem-solving, and recent updates in the relevant technologies, allowing candidates to demonstrate their knowledge and experience. Overall, it was a positive experience, and the entire process was organized efficiently with timely coordination and professional interactions.
There were total of two rounds, first round was online technical assessment which included coding questions.
Selected peers move to next round of interview which is completely behavioural based questions
2 interviews on campus with different department leaders then one phone/zoom interview. Had networked beforehand so my experience may differ. Interview was generally casual, asked typical behavioral questions, very nice folks.
