The AK comment about everyone getting the memo was actually pretty funny, it was a joke he told us to lighten the mood seeing as we all had navy blue suits, white shirts, and red ties.
Best advice I can give you is your white shirt better look good and pressed. The interview room is very very warm, and they will ask you if you want to take your coat off. I accepted, as did I think everyone in my group. I didn't think about it at the time but I'm glad I had a nice white tailored shirt on and good cufflinks, I would have been dripping sweat from the heat if I didn't take my coat off. Good luck
