Decide what you need to capture
A customer interview is a conversation, not a dictation exercise. If you try to write down every sentence, you may miss a hesitation, a change of direction or an opening for a useful follow-up question. Before the interview, decide what the research needs to answer. A short list of topics helps you notice relevant details without treating every remark as equally important.
Recording can preserve exact wording and let you give the participant more attention. Notes serve a different purpose: they mark moments worth revisiting and capture context that audio alone may not explain. You do not have to choose one or the other. A recording paired with selective notes is often more useful than either a full transcript with no interpretation or detailed notes written at the expense of listening.
Ask permission and set expectations
Tell the participant whether you would like to record, why, and who will be able to access the recording. Ask for permission before starting. Explain that declining to be recorded does not prevent them from taking part, if that is an option you can offer. If they agree, confirm that the recording has started; if they do not, rely on notes and allow a little more time after the conversation to fill in gaps.
Plan how you will handle the material before collecting it. Limit access to people who need it, avoid putting sensitive details in file names, and keep recordings and notes only as long as they are needed for the stated purpose. If a participant asks to pause recording or moves into a topic they do not want captured, stop and check how they would like to proceed. Respecting that boundary matters more than preserving a complete record.
Use a light note-taking structure
Prepare a page with the interview topics, leaving space beneath each one. During the conversation, capture short phrases rather than polished summaries. Useful notes include the participant’s goal, what they did, what prompted an action, what made it difficult, and how they worked around it. Mark memorable wording as a quotation only when you are confident it is exact; otherwise, label it as a paraphrase.
A few simple marks can keep notes brief. For example, use a question mark for something to clarify, a star for an observation to revisit, and a time marker to find a passage in the recording. Record your own interpretation separately from the participant’s account. “Could not find the delivery information” is different from “the page is poorly designed.” Keeping those statements apart makes later analysis more dependable.
Protect the flow of the conversation
Give the participant time to finish an answer before looking down to write. If a detail is important but unclear, ask a follow-up such as “What happened next?” or “Can you walk me through that?” It is usually better to understand the example than to capture its first telling perfectly. Brief silences are fine; they may give the participant room to remember or add something.
You can also be open about your note-taking. A simple “I’m going to jot that down so I don’t lose it” explains a pause without making the exchange feel formal. If you are interviewing with a colleague, agree in advance who will lead and who will take most of the notes. The note-taker can flag unanswered questions, but frequent interruptions from two interviewers can make it harder for a participant to tell a coherent story.
Review soon, then turn notes into findings
Set aside time soon after the interview to expand abbreviations and add context while you still remember it. Note where an answer surprised you, which questions remained unresolved, and which parts of the recording need another listen. When checking a passage, preserve the distinction between what the participant reported and what you inferred. If you plan to share a quotation, verify its wording against the recording.
Across interviews, look for repeated situations and meaningful differences rather than counting every mention as a vote. Group observations by the underlying task or difficulty, and keep a way to trace each point back to its interview notes. A useful finding describes what people experienced, the circumstances around it, and what the team might investigate or change. That is the purpose of the record: not to document every word, but to support decisions grounded in what participants actually shared.
