Just FYI, the Malaysians who are flying in Singapore Airlines were not plucked out from some obscure farm who has no interest in flying or can't speak English to save his life. Many of the Malaysians who are in SIA are degree holders from NTU, NUS or overseas universities. They speak English no problem at all. In fact, some of them speak English, Mandarin, Malay and Cantonese.
And, saying that the passing standards of the interview should be changed is counter productive. Why would the company want to compromise the standards of cadets just for the sake of getting more locals? That would be the easy way out. If they can't get enough locals of the proper calibre, they will just hire overseas (which is what they are doing).
Just stating the 'hard truths'.
