Ask customers about a specific recent purchase or problem: what triggered it, what they tried before, how they evaluated options and what happened after choosing you. Follow the sequence of events and ask for concrete examples. Avoid asking them to approve your tagline or speculate about what they might buy someday.

Investigate an event, not an opinion
“Do you like our positioning?” usually produces polite feedback. “What happened the week you started looking for a solution?” can produce a useful account of a buying decision.
Customers do not need to be marketing strategists to help you. They need to describe their situation accurately enough for you to understand the problem, alternatives and value that mattered.
Choose an interview purpose before writing questions. Understanding why customers buy is different from evaluating onboarding or investigating a cancellation. You can touch several areas, but one primary purpose keeps the conversation focused.
Reconstruct the buying journey
Begin before your company entered the picture:
- What was happening in your work when you first started looking?
- How were you handling the problem before then?
- What made the previous approach insufficient at that moment?
- What did you try or consider before choosing us?
- Who else was involved, and what did they care about?
- What almost stopped the purchase?
- What information helped you make the decision?
Follow interesting answers with requests for examples. If someone says the old process was inefficient, ask them to describe the last time it created a problem. Their answer may reveal a deadline, handoff or risk that your current message misses.
Compare the promise with the experience
Ask what they expected after buying, when they first received value and what required more effort than anticipated. Explore what they would miss if the product disappeared and what remains unresolved.
These answers can identify useful language, but they can also reveal a promise the product does not fulfil. Do not discard inconvenient evidence because it complicates the marketing story.
For a churn interview, ask what changed before the decision to leave. Avoid assuming that cancellation means the customer never fit. A suitable buyer can leave because the company failed at delivery.
Keep your own explanation out of the way
Do not finish the customer's sentences or teach them the answer you want. If they misunderstand the product, record the misunderstanding before clarifying it. That confusion may be the finding.
Avoid turning the interview into a sales call. The customer should not have to defend criticism against a stream of counterarguments. Explain the research purpose and agree how notes or recordings will be used before collecting them.
Hypothetical willingness to buy is weak evidence. Past behaviour and specific current constraints usually give you a firmer basis for decisions.
Synthesize without erasing differences
After each interview, record the trigger, previous solution, pain owner, evaluation criteria, objections and experienced value. Separate direct statements from your interpretation.
Compare patterns across different customer outcomes. A common phrase among enthusiastic users may not represent the people who never activated. Keep important differences visible rather than blending everyone into one average persona.
A small interview set can generate strong hypotheses. It does not establish how common every pattern is across the whole market. Test consequential conclusions with additional evidence where possible.
Turn one finding into a decision
Choose a finding that should change the message, qualification or proof. For example, if several suitable buyers only understood the product after seeing a particular workflow, bring that workflow into the early explanation and test comprehension again.
The First 10 Diagnostic includes customer interviews because the strongest marketing argument often begins with understanding what customers already experienced, rather than inventing a more polished claim.
Apply this to your business
Ask a customer to recount the day the problem became worth solving. Record the workaround and the tradeoff they considered, not an opinion about your slogan.
Frequently asked questions
How many customer interviews are enough?
There is no universal number. A few interviews can expose hypotheses, but the breadth of segments and consistency of evidence determine what you can conclude. Record uncertainty rather than declaring saturation automatically.
Should I interview only happy customers?
No. Include suitable customers with different outcomes, recent losses and people who considered alternatives when possible. Interviewing only advocates can hide buying friction and poor-fit patterns.
Need better buyer evidence?
Bring your current interview guide. Mohit can help remove leading questions and find the buying story behind the answers.
