How can I edit the questionnaire after activating the job post?
A questionnaire is only added to the job post once it’s activated. Check this article Creating Questionnaire to see how to create and activate a questionnaire.
Unfortunately, once the questionnaire is activated it cannot be edited.
Before activating the questionnaire, you can go to My Workspace > Questionnaires to see the list of questionnaires.
Click on Edit to amend the template you’ve created.
Another option is to Duplicate the active questionnaire from the drop-down menu and make the edits. Once the questionnaire is ready, Activate it from the drop-down menu and link it to the post.
