Honestly, I do not know the hiring process in Singapore, but in my experience, most companies will not really care about diploma's. They request that you hold diploma X, but they will not truly verify this. The most I've ever had to do was upload a scan of my diploma, which would make forging it a lot more easy thatn produce the true thing with the watermarks and all.
Immediately after graduation people might still care, but later on, barely anyone cares.
But things like this go to show that perhaps people should care more...
The thing here is many companies still asked for your various education certs. Some nowdays they want hardcopies. At job fairs, the HR there asking for hardcopies of your CV. Some even want birth certs and marriage certs. So, we have print print print. There are some that asked for scans upload and originals for verification later.
Thanks for checking out.
