After reading this thread, I am glad STE rejected all my applications as an engineer.

I am working in private sector for 9 years with a diploma and got a part time degree 2 years back.

Maybe they deem NTU NUS as the potentials instead.

Moving forward, I have managed to get offered by DSO, and shortlisted by ministries and stat boards if not for the rejection by STE.

It is a blessing in disguise indeed.
