That means...
Let say 2 applicant
applicant A - Only got a decent 'A' level result,did pretty well in the interview,fully understands the aviation industry,showed deep interest to be a pilot and determined character .
applicant B - Degree holder from a famous university,had rich working experience(hardworking), wanted to join SIA as cadet coz of the high pay,higher than what he is earning currently, have little or no interest in aviation.
So according to limpeh and frealtrimmer, SIA will still take applicant B without even having 2nd thought of applicant A ?
