I really cant give you any details. But I bet its like this.
Do you have a verifiable Licence acceptable to the CAAS.
Can you fly a heading and keep the wings level (I dont know if they give sim rides to direct entry FO's).
Willing to wait 3 -5 years for command.
Welcome aboard
p.s. you should talk to the competition while you're in Singapore, everyone needs pilots.
Good Luck
