All candidates are first brought to a conference room and told that they're not competing against each other for a job. Then a half hour presentation about the company is given followed by a tour of the facility. After the tour, each candidate is placed in a separate office and the interviewers cycle through to talk to each one separately. Each interviewer has a topic that they're supposed to talk about and each session lasts around 20 minutes. I talked to 7 different interviewers before I was brought back to the conference room for lunch. It was a lot of people to talk to in one day, but I took quick notes about what we talked about after each one and was fine. Ask a lot of questions. They want to know you're interested in the company.
