I applied through college or university. The process took 2 months. I interviewed at CHS Inc (Manhattan, KS) in Jan 2015
Interview
I talked to them at a career fair. Then I got a next day interview. They told me that they would get back to me after a month. Like most companies it was probably closer to two or two and half months. Interview process was kind of weird. They re-stated my answers and then asked if that's what I was thinking, then wrote it down. Overall, it was pretty good, but awkward. Hopefully you have a better experience.
I applied through college or university. The process took 8 months. I interviewed at CHS Inc (Manhattan, KS) in Oct 2018
Interview
They asked questions from a questionnaire and wrote down your answers/notes about you as you answered their questions. It was a one on one interview, and no questions were exceptionally difficult to answer. I interviewed with them in September and didn't hear back from them until the middle of May.
