It's nearly ten years since I joined BUAS, but back then we had an informal chat for around twenty minutes at Fresh fair, then on successfully passing that, a formal interview with the Sqn boss and two other officers. Know your age in years and months and be ready to answer quickly - that was the first question I got. Other questions were fairly predictable - why do you want to join BUAS? What course are you studying and why, what would you want to fly if you joined the RAF, what do you think of gays in the forces, do you take drugs, what do you think of the RAFs stance on drugs, what is happening in the world, what do you think of the situation in (insert name of troublespot here) Can't remember much else right now - it was a while ago. Finally a medical at Lyneham. Good luck.
