Hi Kjoiful,
I always read that people always wonder how they pick candidates but I think and what is known are the basics, just someone that is very well groomed (they have a classic look), smiling (all the time basically), genuine, polite, positive.
The thread has a lot of information about how you should look and I think it helps if you try to make your resume (cabin crew friendly) to help you pass the first stage.
Good luck
