Years ago at Cranwell on IOT, I had a cadet with a shed-load of gliding instructional hours, but coming in as an Air Trafficker. Cut a long story short, he was a victim of the recruiting world quota system. Luckily, had a Director who regularly told the establishment to p*ss off, and, subject to satis performance at Swinderby, would be allowed to transfer to GD/P.
Now a V experienced RAF pilot...
He spoke highly of the gliding world, and all that it did for recruiting.
