I just don't know what to tell you now. Just hope that QR will contact you soon. But, if there is still no response like this then you should consider to reapply with QR. QR tend not to give regret letter, but they tend to lean on 90 days response period.

By the way, did you get an email from them that you have been "Short listed and kept in their holding pool"? To be consider as a "Short listed" applicant with QR, you must receive this email.

Normal process would be
1. Online application
2. Invite for interview, testing, and etc.
3. Final result
90 days period apply to all of these 3 steps process.

Wishing you best of luck in resolve this issue with QR.
