Well lets hope the interview process has improved. I know somebody that went a couple years back in 2018 and said it was a disaster. The feedback from lots of pilots is that at the time (not sure about now) was that they came across as very arrogant and not interested in foreigners in the slightest.
I have heard the interview is done over 1 day now including the sim instead of being called back but then again I cannot verify that information, maybe a recent attendee can. Im sure COV-19 will not help the situation now but lets see what happens.
