I got an on-site interview from a career fair at a conference. There were 2 interviewers. It was very simple and straight forward. They asked a mix of behavioral and situational questions.
I applied through college or university. The process took 2 weeks. I interviewed at ADM (Champaign, IL) in Oct 2014
Interview
Met with a college recruiter at the college career fair, was called that evening to set up an in person next day interview. I met with the same recruiter for a half hour interview. Then I received a call about a week later in which they gave me an offer.
