I was in the afternoon interview group, so we took the tour in the morning. After lunch, a faculty member came to get me for my individual interview, which lasted about twenty minutes and was entirely stress-free. No hardball questions, just friendly conversation, and he had seen my personal statement, my undergrad institution, and my GPA. After that, I went upstairs for the group interview with two other interviewees, who I already knew from the morning tour. The interview was conducted by two faculty members and the student who had given the tour, who I had also talked to a lot before lunch. The interviewers had seen only our personal statements and colleges, but not our grades or credentials. The questions were aimed at only one person at a time, so I never felt like I was competing to get a word in, and most of the questions were not repeated for the other candidates, so I didn't have to worry about their answers being better than mine. It really wasn't all that scary.
