Customer Interview Prompts for Better Business Evidence
Prepare neutral questions, explore real customer experiences and separate observations from assumptions. Eight prompts help a small business learn before changing an offer.
By LifestyleGlide · Published · 6 min read
A useful customer interview is about what a person has actually experienced. “Would you love this product?” encourages a prediction and may invite a polite answer. Ask about a recent situation, what they tried and where the difficulty appeared. Keep the conversation open enough for an answer you did not expect.
These prompts help prepare a discussion and organise approved, anonymised notes afterwards. Explain the purpose of the interview, obtain appropriate consent and avoid sharing names or sensitive details with an AI tool. One conversation can suggest a question to investigate; it does not prove demand or represent a whole market.
Start with this workflow.
Name the uncertainty
Choose one decision the research should inform. Write the assumption you want to test before designing the questions.
Ask about a recent situation
Explore the person’s actual steps, alternatives and constraints. Avoid presenting your solution before understanding the experience.
Separate notes from conclusions
Record what was said, your interpretation and what remains uncertain in different fields. Look for counterexamples as well as repeated themes.
WORKED EXAMPLE
Ask about a recent workaround
Illustrative example: an owner is considering a scheduling tool for tutors. No interviews have happened yet.
STARTING POINTWould you pay for our brilliant scheduling app that saves hours?
AFTER CHECKINGTell me about the last time a student changed a lesson time. How did you handle it? What did you use to keep track? What, if anything, was difficult about that process?
What changed The questions invite a real account without advertising the solution. The answers can inform another test, but cannot establish willingness to pay on their own.

INPUTS
Business decision, assumption and existing evidence
PROMPT
I am considering [decision]. My assumption is [assumption]. Existing evidence: [notes]. Suggest three interview objectives that would reduce a specific uncertainty. For each, identify the type of recent experience I should ask about and a limit of what an interview can establish. Do not claim that the assumption is true or that interviews prove demand.
INPUTS
Research objective, relevant experience and constraints
PROMPT
Create a participant brief for [objective]. Relevant experience: [experience]. Constraints: [constraints]. List inclusion criteria based on behaviour, exclusions with reasons and recruitment questions that verify the experience. Do not use unnecessary personal characteristics or sensitive data. Do not assume that a convenient sample represents all customers.
INPUTS
Objective, topic, interview duration and known context
PROMPT
Build a [minutes]-minute discussion guide about [topic] for [objective]. Context: [notes]. Include a simple purpose statement, a question about a recent relevant experience, probes about steps and alternatives, and a closing opportunity to add something. Keep questions neutral. Do not pitch my proposed solution or script the participant’s answers.
INPUTS
Draft interview questions and research objective
PROMPT
Review these interview questions [questions] for [objective]. Flag questions that lead, combine multiple issues, use jargon or ask for predictions rather than experience. Rewrite each flagged question neutrally and explain the change. Preserve the research topic without suggesting that the participant should agree with me.
INPUTS
Anonymised account, unanswered areas and objective
PROMPT
Using this anonymised account [notes], suggest follow-up questions about the sequence of events, alternatives considered, constraints and the outcome. Unanswered areas: [areas]. Objective: [objective]. Do not fill gaps in the account or infer motives. Mark questions whose answers may not be relevant to the decision.
Separate evidence and interpretationOpen the prompt +
INPUTS
Anonymised notes, source labels and decision
PROMPT
Organise these anonymised notes [notes with labels] for [decision]. Use columns: observed or reported detail, source label, interpretation, alternative explanation and unresolved question. Preserve uncertainty. Do not invent quotations, merge different people into one account or treat my interpretation as a customer statement.
Compare themes without manufacturing a consensusOpen the prompt +
INPUTS
Approved notes from several interviews and objective
PROMPT
Compare these approved anonymised interview notes [notes] for [objective]. Identify repeated themes, exceptions and conflicting accounts. Attach source labels to each theme. Describe missing evidence and sampling limits. Avoid invented percentages, prevalence estimates or a claim that everybody wants the same thing.
INPUTS
Interview observations, uncertainty, options and constraints
PROMPT
From these observations [observations], remaining uncertainty [uncertainty] and options [options], propose a small next test within [constraints]. State the assumption, what I would observe, a decision rule I must approve and what the test would not establish. Do not forecast revenue or imply customers have committed to buy.
These are original, editable starting points. A prompt does not complete an action outside the conversation. Use approved inputs and review facts, source material and commitments before using a result.
