There are actually TWO separate interviews. The first is the closed-file group interview (75 min), with three interviewers and three applicants. They ask sometimes the same question to all three, and sometimes completely unrelated questions to each person. At the end they give a group question to work on (see ''interesting question'' above). The second interview is a brief (~20 minutes) open-file session with one interviewer. Really laid-back and non-stressful.
