Internal/External Prescreening Questionnaire and Interview Questionnaires

Hi,

I want to add questions in "Create Job requisition" task in the following sections:

• Internal Prescreening Questionnaire
• External Prescreening Questionnaire
• Interview Questionnaires

I have created a question from "Question Library" task, under Recruiting, than I have create a questionnaire template and a questionnaire based on the question. From "Enterprise Recruiting and Candidate Experience Information" task I have selected "Prefill Prescreening Questions in External Candidate Applications".

1. Have I done all the necessary configurations?
2. I have also to create a questionnaire templates and a questionnaire? Or I have only to create a question?
3. What is the difference between these sections?
4. Where does the output appear after entering the question in each of these sections?
