Koch interview questions

My recruiter called me with the opportunity and asked to send my resume over to Koch. Koch replied the next day that it was interested in having a telephone interview with me the following week. My first telephone interview was with a Koch Recruiter who asked mainly your typical behavioral interview questions (i.e. greatest accomplishment, situation where you had a problem with a co-worker or boss, personality traits). She contacted me the next day and told me that the company would like to have a 2nd phone interview of a more technical nature. I interviewed with a Director - technical in nature. Koch called me the next day and said they would like to fly me out to KS so I interviewed on site at Koch Industries with 7 people in a day (an HR rep first, the Director of the department for the position I was interviewing, and each of the department heads of IT. I got a call back a few days later and was made an offer.
