I applied through college or university. The process took 4 weeks. I interviewed at Koch (Wichita, KS) in Oct 2015
Interview
Recruited at the university career office. The initial interview consisted mostly of behavioral questions. It was was followed by second interview in Wichita which was more specific to the company and Koch's business philosophy. We were reimbursed for travel expenses. Mostaly behavior-based questions regarding various work-related scenarios. Emphasis on Koch's philosophy. It was difficult to finish reading and be able to converse about the Koch book as the interviews were held during midterms.
