that s an interessant topic you raise here RowleyUK !
As a matter of fact, I am wondering what is the importance of non aviation professional experience of a low houred pilot.
In fact, would a chief pilot pick Mr. X rather than Mr. Y, as they both have less than 300 hours flight time, but X has an MBA in finance with 2 or 3 years of professional experience on financial markets (....), and Y does not hold a college degree and a "Paper round and Saturday morning shop assistant " experience ?
