REALLY?!!! So you are telling me someone who doesn't know how to hold, gets off altitude by 800 feet, and nearly stalls the sim on a non-precision approach has the same chance of passing training as the guy who shows up prepared and can fly a flawless sim evaluation?
I'm sorry, you are right. A PRIA from "Ed's Flight School and Crop-dusting" gives the airline much more insight than a full interview.
Pilots like you are so scared to actually have to prove their abilities during an interview. That's why you complain that other airlines do a decent vetting process. You took the path of least resistance. That's fine. But don't complain when other airlines want to hire more ambitious pilots who prove themselves during an interview.
