It's possible to modify the title and the due date of a campaign after the campaign's launch. A campaign due date is only informative. Employees and their managers will still be able to complete their interviews even if it has passed.
1. Go to Performance > Campaigns and select the campaign of your choice.
2. Click the three dots within the campaign detailed page, and select Configure.
3. A new menu opens on the right side to allow you to change the title and due date.
4. Click Save changes.
