You can add a candidate to a job straight from their profile, which drops them into that job's pipeline.
How to assign to a job
Open the candidate's profile.
In the action sidebar, click Assign.
In the dialog, search under Jobs and select the job you want.
Confirm to assign.
The same dialog can also add the candidate to a talent pool — each assign targets one destination, so pick a job or a pool and confirm.
What happens after
The candidate appears in the selected job's pipeline.
The team on that job gets access to them.
That job's automations apply as they move through stages.
If they're already on the job, a duplicate assignment is prevented.
A candidate can be in several jobs at once — each application is tracked separately in the sidebar's Candidate History.
