To dispel a myth here, Capita has little to no part to play in RAF recruiting. It is all in house, so if the ball was dropped, it was dropped by the RAF.
All capita provide to the RAF is infrastructure in Army sponsored careers offices and medicals to candidates.
For further clarity, you cannot join the reserves through an AFCO (Armed Forces Careers Office). You join through the reserve Squadron you wish to join.
Happy to clarify any points further if anyone has any interest in the process....
