The question is why should they take you instead of a singaporean?
You are getting paid the same amount as a singaporean. No benefits here.
They have to invest more time and money on you.
Your results might be questionable. (some universities in Malaysia has very "loose" academic standards, and most students score based on memorising and doing "past year" questions.). If they take in NUS/NTU at least they know what to expect.

I've actually seen cgpa 3.8 failing simple electronic fundamentals.

Or it might be your resume is generic, unimpressive with lots of grammatical errors. (This is my first impression, judging from how you reply here)
