Only those who align with BA's point of view get the nod.
And that's conducive to:
BA's secret in recruitment falls between the lines of lateral thinking (thinking from outside the box) to arrive at what you want.
Is it?
Incongruously juxtaposed wouldn't you say?
It's my opinion that it should be a long grilling about why you want to join, who you are, what you've done and where you want to be. And then a solid sim - lots of raw data, holds, bad weather, some failures, some CRM issues and a nice lunch together somewhere in between. Any other pseudoscience is there to make CC/pilot-cum-psycologists feel justified and remove accountability like any good manager should. 'Twas the selections fault m'lord.
To counter your argument for BA's selection- are you noticing a difference between BA selected pilots and BMI unselected pilots? Voila! Think outside that box. Personally, I choose not to get in it in the first place.
