Hi Gil,
You want to make sure that you have an association between the interview and the answer. Otherwise you cannot figure out who gave which answer to a specific question.
The following section of the Rapid Learning Path will give you some insight in how to use Information Entities in your model https://academy.mendix.com/link/modules/93/lectures/2794/-5.3-Information-Entities
Below is a simple example on how you could set it up
When you create an interview, you will probably want to use a microflow to do the following (starting from the Job)
Create Interview and associate to Job
Retrieve All Questions related to the Job
Create a list of Answers
Iterate over the QuestionList
Create an Answer for each Question Iteration and associate to the Iterated Question as well as to the Interview
Add the Answer to the list
Outside of the loop you can commit the answers and the interview
Open a page where you display the interview (on that page you can also display the list of answers)
Hope this helps
