There are some unsaid rules at CX as to what countires the pilots come from, where as EK, EY, QR etc etc are taking pilots from India,Malaysia and other brown asians, CX will just not do that. What ever CX may say thats the "rule".
So true about the US/UK mailing address, I know of a few guys who got in as DESO the same way.
Very true about 2000TT ozys / Canadians getting in as DESO.
Some things will never change
