Etihad stopped accepting applications for the cadet pilot assessment early this year because all of the places got filled up.
I assume thats why you didn't get a reply from them.
They might put your application on hold for next year's assessment but I am not sure.
You should contact them and ask them or re-apply for next year's assessment.
Applications for next year's assessment should be open by the end of this year, on the Etihad careers website.
Best of luck
