As far as I can remember, BACX had a screening process in place at the initial telephone call to request the application form. As long as you met the minimum requirements (basically fATPL and 50hrs in last 6 months) you got the form. As for the essay questions, I always understood that to be something for the psychologists as some form of psychometric testing prior to interviews rather than as a discussion topic for interview - although I'm sure they would use it for that.
Admittedly it is a strange way to run the process, but then again, at least it gives a more level playing field than using the old boys network. Which would you really rather have?
