Just received my letter inviting me to an interview on the 16th of November. Apparently the interview lasts 2 hours! This is my first face to face contact with my ACO, so was hoping it would be more informal, like when you do your barb test etc for soldier entry. Anyone got any advice on what I should do to prepare? The other half thinks I should put together some sort of portfolio or presentation to make myself look wonderful, good idea?
