By default, candidates can only take the test once.

If you have allowed more than one social login, it is technically possible to take the test again, using different login.

If you would like to allow a candidate to retake the test, you can delete the candidate and they will be able to retake the test. To do so open the job and click open the candidate, select the 3 menu dots in the test results, and click on the Delete option.

Note that only Admins and Owners of the workspace are able to delete candidates. Managers can't delete candidates.
