Whilst due diligence is certainly required, I think the point is often the 'intellectual' interviewers do not understand aviation.
But maybe its a myth, no sarcasm, because at the end of the day most capable pilots I know have good jobs.
Personally Cathay passed me over (dodged a bullet there) for not knowing what the name of some obscure aircraft in a museum's name was, but I worked for other Asian airlines without issue and also passed Jetstar and QF assessment.
