I can categorically state that there is NO hidden agenda regarding BACX pilots. The recruitment is done by line guys, most hold a training appointment and are often unaware of the guys previous company. If they are good enough on the day they will get in - simple as that.
Rythm Method
you say you fly with good guys evey day -maybe so but perhaps they didn't perform at assesement, or maybe that your criteria differs from the BA selectors.
And yes, before anyone asks i am part of the recruitment team.
