Depending on your how your organization is configured and the number of jobs a user has been assigned, it can be challenging to find a particular closed job. Use the closed jobs filter from the All Jobs tab to make searching a little easier.
Note: Users can only search for Closed jobs where they held Job Admin level permissions or higher at the time of the job's closing.
Click All Jobs from the navigation bar and expand the filter panel at the top of the page.
Navigate to the filter panel and select Closed from the Job Status dropdown menu.
Once Closed is selected, the jobs list will auto-populate to match the filter criteria you have selected.
