yes it can be interesting talking to the recruitment people.
a little chat with a technical fleet manager revealed (or perhaps we should guess from the way BA themselves work) that they have to now abide by strict BA procedure, and you will only proceed to interview if your essay writing skills pass their grading. i.e it was freely admitted that those interviewed may well be better writers than pilots and in the past have had to turn down applications from 5000hr pilots etc
And you thought the game stopped once you passed your exams and flight tests?!!
