I applied on-line through my university's career services. They then called me and gave me a behavioral interview. I was abroad, so my second interview was on the phone, although they are usually in person, and with another manager (probably also because I wasn't going to be there in-person, to get another opinion before committing). I prepared by reading information about the company and their values.

A little intimidating they were not receptive. Had two people there in person, one engineer and the other HR, Was held at a career fair. They had a checklist. Mostly behavioral.
