A friend of mine, B777 cap, fed up of the sand pit as well, just returned from the interview/sim in IST.
SIM: hotel pick up late 1,5 hours; 737 sim, which my chap flew last time 25 years ago. Guys shouting in Turk, chaotic scheme, multiple failures, very unprofessional, to say the least. He just asked to stop the sim and told he don't need that s....t.
Packed his stuff and flew back.
Interestingly, he's not the only one that tell that.
