Talked to the recruiters at my school's career fair. They look at your resume and immediately decide if they will invite you back for an on-campus interview the next day. You sign up for a time slot and prepare for your interview. The interview is pretty relaxed and totally behavioral (i.e. tell me about a time you worked in a group project and overcame a conflict, tell me about a time you were faced with an ethical decision, etc.). The interviewers (two of them at once) were very nice and helpful. If that interview goes well, you will be flown out to the headquarters in Moline, IL for a final interview. There you have two interviews, each with one person from your field, which are essentially the same type of questions from the first inverview. They will typically respond in a few weeks after your last interview.
