Are they still doing that '6 months as a Plt Off' thing? We had an ex-apprentoid on 14GE who had amassed a shed load of seniority antedates for apprentice time, Flt Cdt time and degree class that one day he was a Plt Off - and the next a Flt Lt.
Not quite as good, though, as the chap who, when he arrived to start IOT, actually outranked his IOT Flt Cdr!
Good luck!!
