Similar thing happened in indoc. I didn't find out about it until sim. One of the guys said 'oh , yeah. we had the copy of the indoc tests'.
Needless to say that guy got eliminated through natural ways.. (barely passed the oral, couldn't perform in sim)..
For all those cheating people who got hired in airlines, there are a lot more than you who got there by working and studying their asses off; and there are a lot more who would like to take your place..
