Once a candidate is in your organization's hiring pipeline, you can add them to another job, transfer them to a different job, or simply remove them from a job. Only users with Site Admin permissions can remove candidates from jobs.
To remove a candidate from a job, navigate to the Candidates page and click on the candidate you want to remove.
Click Add, Transfer or Remove Candidate’s Jobs in the lower right corner.
In the window that appears, click Remove Job.
Click Remove from this job and make prospect.
The candidate has been removed from the job and is now a prospect.
