Good English, pleasant and mature personality, friendly, confident. Pretty standard stuff for any world class MNC, especially in the service industry. Imagine yourself as an interviewer I guess. All these qualities come into play during interview. The other things like education, eyesight and etc., are as stated on the website. Once you get called up for interview, don't worry about them anymore because if you don't meet the requirement they wouldn't have invited you for interview at all. The rest is down to qualities as stated in para 1 above. Just a note on flying experience: seriously don't worry about it. Even if you've experience but you screw up the interview, they still won't take you.
