These are some "proven" Interview Questions to use for Case Study/Testimonial interview. This approach will help solicit quotes, insights, and input for your messaging framework. I typically set aside about 45 minutes for these, and use Zoom to record the conversation, so I can focus on the dialogue vs. taking notes.
Introduction of the Customer Interview
Thank the client for making the time, and verify how much time the client has for the interview.
Ask if this interview can be recorded so you can focus on the conversation.
Confirm that the materials will only be used publically after approval by the client.
Note that some questions may feel repetitive. This is by design to get to the “gems”.
