Within Recruitment settings, there is an option to allow managers to be able to add and edit candidates. This can be done via the candidate card or through a requisition.
To enable this setting, go to:
Administration > Company > Settings > Recruitment Settings
Allow managers to add and edit candidates - if set to 'Yes', managers will be able to add candidates by clicking on the 'Add' button via:
Recruitment > Candidates
With this enabled, managers will be able to add candidates and edit the candidates added for any requisition for which they are set as the hiring manager.
They will still be limited in their ability to delete records, move candidates into employment and other recruiter functions.
To add or edit candidates on a requisition, a manager would need to click on the magnifying glass against the requisition. They can then click the 'Add' button to add in a new candidate, or the 'Edit' action in the actions menu of an existing candidate to edit them.
When the manager clicks on add to add a candidate, he will only be able to add a candidate for the job role for which they are the hiring manager.
