Will this be in London? Will it be in a warm room? If so then definitely A314 and IH, maybe one spray or two of IO (or IS or MX289 which lasts longer) just to make you seem openly charming with an emphasis on more IH with a good level of A314.
I had an interview with 2 gals and a guy; I knew the guy and 1 of the gals. I wore MX292, Instant Shine, and Instant Openness. The interview went very well all eyes were glued on me and everyone was in a very good mood.
