Notice that closed and private jobs aren't the same. Here’s the difference:
- A closed job means you’re fully finished hiring and don’t want to receive new applicants. There’s also no need to communicate with applicants anymore. Everyone is either rejected or hired. You also won't be charged for closed jobs.
- A private job post means the job post is still active, but not visible to the public anymore. You either don't wan't your job post public from the beginning, or you've received plenty of applications and don't want to receive any more. So the big difference is that this job post is not visible on your career site, but it is still accessible on your dashboard. You can share a unique private link to this job post, so people can still visit (and apply). Because it's still an active job post, you are charged for private job posts.
Most companies publish their job posts open to the public. When they have received enough applicants, they switch the job to ‘private’ and start reviewing and communicating with applicants. When they've hired someone, they finally ‘Close’ the job.
