An interview brief should help a guest arrive prepared without asking them to memorise a performance. Give them enough information to understand the conversation and the recording arrangements before the session begins.
Explain the scope and practical details
State the subject, approximate recording length, format, and intended audience. Identify the broad questions or themes you expect to explore. If a particular document or example would be useful, request it clearly rather than surprising the guest during the recording.
Explain where and how the recording is intended to be used, and agree the relevant permissions and review arrangements. Requirements vary with context and location; do not present a short email as a universal legal release.
Distinguish preparation from a script
Let the guest know whether the questions are indicative or fixed. If follow-up questions may arise, say so. Avoid promising a final edit or approval process that the production team has not agreed to provide.
Close with the joining instructions, a contact for practical problems, and any simple recording guidance already tested for your setup. Invite questions before the session. A useful brief reduces uncertainty about the process while leaving the guest free to explain their experience in their own words rather than reciting answers written by the interviewer.
