I received the same email from the HR department as well. Since required to sent in NRIC,transcript/degree scroll,latest results and spm results.all document need to be certified true copy. I just fill in my resume and register at their website and since there are no position to apply there,was a bit shocked that the HR department sent the email. You can try by registering and fill in your details at the discover website

If im not mistaken for me around a week or two.just sent all documents and declaration form 2 days ago.the due date supposed to be yesterday.guess its too early to expect any reply from them
