4T, no, but I recall a moan by Flt Eng whose son was applying to join the RAF. He observed that if you read the Times or the Telegraph and had 5 O-Levels you could become an officer. If you read the Mail or Express and had at least 4 O-you levels could become NCO aircrew
Higher level recruiting was via newspapers rather than AFCO with application direct to Adastral House; AFCO was aimed at airmen.
