Notice how the captain had to call his union rep, chief pilot, and HR person..CYA, right down the line..probably because he flew with the guy FIRST, THEN decided AFTER the flight to bust him...
Captain probably could have gotten in trouble for even doing the flight...so he was probably playing the game of only noticing the stinker 'enroute'.
Anyway...at your typical airline interview these days, it's a crapshoot if they want you to turn the capt in, or let it go, or call the chief pilot. Every outfit is different...some looking more for robots then others...
