Hi

Just looking for suggestions here.  Our recruiters for reqs often change hands.  Has anyone tried or been successful in creating a time to fill report for recruiters when this occurs.

For example:

Req 1234 is posted on 1/1/18 and Recruiter 1 is listed on the req.

On 2/1/18 a new recruiter (Recruiter 2) is assigned to the requisition.

The position is filled by Recruiter 2 on 2/15/18.

Recruiter 1's time to fill is 31 days

Recruiter 2's time to fill is 14 days

Specifically I am looking to see how you would track this change using OBI
