One question that candidates may be asked is:
"How long have you been interested in a career in the Royal Air Force?"
the next question is likely to be:
"What have you done to foster this interest?"
then they may ask:
"Why didn't you contact us 2-3 years ago?"
Candidates would be well advised to mug up answers on what are banker questions.
A similar set may include hobbies, sports etc.
