NSU does group interviews... I also went through that process last year and was accepted but decided the program was not a good fit for me (I would really love to be at FAU). Their interview was a group/panel interview, so a few students and a few professors/administrators. First they had everyone introduce themselves, share a bit about themselves and why they were pursuing the program. Then they asked a seemingly random question that was more about personality than accomplishments for each candidate... Some were... If you could be any fictional character who and why? If you won a million dollars what would you do with it? If you were a type of flower what flower would you be and why? If you have ever seem the "if" books I am fairly sure that is where the questions came from. I have also done group interviews in my former career and some were each person has a question like NSU and some were more about seeing how the candidates bounced off each other and interacted. So long story short I have done a few and they were all very different... not sure what we can expect if selected. Eeeek!
