Impatient-
I agree with Deli- it sounds like the person did the mini mental state exam. Just so you know, at least in the US, most people can't go back five presidents, even if they were alive for all of them, or they get them out of order or something. So it was impressive that you were able to get all of them. I also think that the structured sense of the interview was probably because he did have a set of questions that he had to ask so that everyone has the same questions. I will keep my fingers crossed for the outcome of your review.
