Jonathon, they will expect you to have a good understanding of your trade and RTS. Firstly RTS, you should know where it is held, for how long, the various phases and what's involved, i.e Ground Defence phase will incorporate Weapons handling, field craft, NBC, Respirator test facility and consolidated at the end of the phase by Exercise Blue Warrior. For your trade training you should know that it is held at RAF Cosford, the duration, what is the role of the trade? what do you expect to be taught? your first tour? follow-up training? transferable skills - modern apprenticeship? etc, etc, etc. Once you've completed your training you'll be involved with flight line maintenance then trade rectifications (radar, avionic systems, black box out - black box in!). Know about the RAF, it's roles and where we are and why we are there, i.e deployments, bases, operations, etc. How do we fit into NATO, what is NATO and why did it come about? How many member countries? What stations do we have at home and abroad, how many could you be posted to (flying stations obviously for you!) Finally your attitude to combat/conflict, your motivation and commitment to service/trade, are you physically prepared? The personal stuff is easy as only you know about you! so sell yourself, responsibilities within school, UYO's, STA's, employment, etc. If you need any further assistance remember I'm 'Here to help' and good luck!!!! Remember relax, be punctional, smart, sit up, don't fidget and maintain good eye contact! but most of all don't lie!
