After meeting and talking with recruiter at the ConAgra food booth at the career fair, I received an e-mail requesting a first round interview. First round was fairly standard: one hour interview with a director and either an HR person, or manager. It was all behavioral questions, (tell me a time...) nothing out of ordinary.
About a week after the first round, I was contacted by someone from headquarters with an invitation to second interview in Omaha. Flew over, was given a tour of the campus, as well as the city. Had three more interviews with a couple more director/managers. Received an offer 2 weeks after second round.
