Applied online through my school and company website. Needed a cover letter. Recieved an email that I was invited for an on-campus interview and interviewed with an alum. He explained the format of the interview before we started so you know what was coming, but it was a pretty standard behavioral interview (tell me about a time when...) Use the STAR method and be ready for follow up questions about how or why you made the decisions you did. Ask questions, I wish I had prepared more. I heard back in about a week.
