ATO - merit pool to offer

Hi! I recently applied, completed an interview and reference check for an APS4 economist role with the ATO. I got an email that I’ve been placed in the merit pool. How long does it typically take for offers to be made? And how can I know when they have made offers?

I’m getting really anxious waiting for it! It’s been a bit rough with the job market lately so I was really hoping for this job!
