I applied online and reached out to a contact at the office I applied at, then received an email that I wasn't moving forward through the interview process. Four days before their super day, I received a text from their university recruiter asking me to come in and interview. 8 other people interviewed that day, I believe. Each of us were in a conference room and 4 interviewers came in at separate times for 30 minute interviews. They had set questions and took notes as to your answers. Each of the interviewers stuck to their specific questions and left some time for their own at the end. At the end of the 4 interviews, we got to ask current associated questions.
