Currently, it is not possible to set an expiration date on any of the assessments unless you are on the Enterprise plan.
Candidates have 4 days to complete the online skills assessment and are sent an email reminder 48 hours before the expiration.
They have the option to request more time from their accounts. If they request more time, you will receive a notification in-app so you may extend the deadline in the Candidate section in the Invite tab. You can extend by clicking on the 3 dot menu as shown below, and choose Extend. You can also choose to extend the deadline before they even request it.
If multiple candidates request more time and you would like to extend them all, you can click on the number in the Extensions section in the top stats bar and you will be able to Approve all requests at once.
Enterprise Plan Customers
