Not sure what you mean by this?
Recruitment will identify potential which is then exposed to state-of-the-art training facilities. So growth is attained in attitude and aptitude to acceptable values.
I doubt that Jodie got to that level without demonstrating potential, no! BA has so many sieves in recruitment to come through; Some might have good and first hand knowledge of this but IMVHO it's a question of genuine interest and passion or attitude that gave way.
