I applied for a job last November/December 2023, spent a long time completing the application, and had no response back?

I have not even had an aknowledgment that my application was received, and i applied before the closing date. Absolutely shocked that no-one has contacted me.

Hi, I'm sorry that you have had to go through this experience. Normally you should be notified of sift results following a full application submission. The advert will have a point of contact and there will also be a contact for Government recruitment services (GRS). Do check your junk email in case the notifications have gone there. If the application window has closed you will be unable to access the advert online unless you saved a copy.
