on the other hand I have seen guys get hired at majors and Big-3 with checkride and training issues. The "big picture" theory applies. Was it 20 years ago? New in their career (ostensibly the case of this regional scenario) ? With otherwise good performance and resume filler? recommendation letters and guys "vouching for" the guy?

or a checkride failure every other year ?

some companies want applicants to disclose EVERYTHING even "additional training" needed at ANY STAGE post Private Pilot issuance.

Imagine the Instrument ticket/Private Pilot stage because they needed work on holding entries. some applications out there are "since obtaining your private pilot, have you EVER required additional training"

"lets polish up your holds, they are passable but lets tweak them. how about we do some holds tomorrow for 2 hours?"

airline career tubed?

no of course not

etc.
