To unfill and reopen a requisition, disqualify the candidate attached to that req. The requisition will automatically revert to the Open status and can be filled with a different candidate.
If you need to update the start date or salary details for a filled req:
- Move the hired candidate back to the previous pipeline stage
- Disqualify the candidate to reopen the requisition
- Requalify the candidate
- Move the candidate back to the Hired stage, entering their new salary and start date info
