Spend a few minutes reading the Fragrant Harbor section on this very forum and you'll see what you're up against. You won't get anywhere near a Cathay S/O job until you have several thousand hours on turboprop / small jet and even then you'll have to be very very very good. Despite what it says on the website as minima, when I did the interview a couple of years ago I was the only person in the room with less than 4000 TT. 8 out of the 10 guys in my group had time on smaller jets, quite a few as captains. And after all that, only three of us got the job
Good luck with your training ...
