The truth is – most customer interviews don’t improve positioning, they just confirm what the team already believed. Ask someone what features they want, and you are likely to get a wish list. Ask them what they like about your product, and you get polite validation. Neither of those produces the thing positioning actually needs: a clear, specific understanding of what a customer was really doing before they chose you, and what they would have done instead.
That distinction is important because positioning’s first and most important input, the real competitive alternative, isn’t something you can guess your way to.
It has to come from reconstructing an actual decision someone made, not from asking them to describe their preferences in the abstract. Here’s how to run interviews that surface that kind of insight, using a technique built specifically for this purpose.

Why Most Interviews Don’t Surface Real Positioning Insight
The core problem is that standard customer interviews ask about the present, “how do you use this product,” “what frustrates you,” “what would you change.” According to research from customer research platform Qualz.ai, this framing produces genuine but shallow feedback, because people are far better at describing what already happened than predicting what they’d want or reconstructing why they actually decided something in the first place.
Jobs-to-Be-Done interviews take a different approach entirely, focusing specifically on transition moments, the points in time when someone decided their current solution wasn’t good enough and went looking for something else. That transition moment is exactly what positioning needs to understand, because it’s the moment your real competitive alternative reveals itself.
The Switch Interview: A Purpose-Built Technique for This
The most directly useful method here is the switch interview, developed by Bob Moesta and Chris Spiek and refined at the Re-Wired Group, built specifically around reconstructing a customer’s actual switching decision rather than asking for opinions.
The four forces. According to the Jobs to be Done framework’s own documentation, every switch is a tug-of-war between four forces. Push is the frustration with the current situation that started the search. Pull is the magnetism of the new solution and the progress it promises. Anxiety is the fear and uncertainty about the new, unproven choice. Habit is the comfortable pull of whatever the customer already knows and does. A switch only happens when push and pull outweigh anxiety and habit combined, and a well-run interview surfaces all four, not just the positive ones.
The timeline. According to a JTBD interview guide published by Perspective AI, the interview reconstructs a specific sequence: first thought, the moment the customer first realized their current solution wasn’t working, and what triggered that realization, passive looking, casually noticing alternatives without actively searching, active looking, when the search became intentional and real criteria emerged, deciding, what actually tipped the final decision and what almost stopped it, and consuming, how the first real experience matched or didn’t match expectations.
A useful opening line, recommended by JTBD practitioner Alan Klement and cited across multiple JTBD guides, sets the tone for this kind of documentary-style recall:
“Imagine I’m filming a documentary. I’m just trying to understand how people buy . Anything you can tell me is going to be useful.”
This framing invites detailed, specific storytelling rather than the summarized, sanitized answer most interview questions accidentally invite instead.
The switch interview, developed by Bob Moesta and Chris Spiek, reconstructs a customer’s actual purchase decision across four forces, push, pull, anxiety, and habit, and a specific timeline from first thought through active searching to the final decision. Unlike standard interviews that ask about present-day opinions or feature preferences, this technique surfaces the real competitive alternative a customer was weighing, exactly the input positioning work depends on.
Why This Matters for Positioning Specifically
The connection back to positioning is direct and concrete. A well-run switch interview reveals what your real competitive alternative was, not the alternative you assumed, and that finding can reshape an entire positioning strategy.
Two real examples make this concrete. Casper, the mattress company, ran Jobs-to-Be-Done research and identified that its real competitive “alternative” for many customers wasn’t other mattress brands at all, it was Zquil, a sleep aid. Customers weren’t comparing mattresses to mattresses, they were comparing a mattress to any other way of solving the underlying problem: not sleeping well. Repositioning around that insight, with a single ad addressing that real alternative directly, reportedly increased sales by 37%. InVideo, a video editing company, used similar research to discover their winning segment wasn’t expert video editors as originally assumed, but complete beginners, a repositioning that reportedly took the company from zero to $25 million in revenue within six months.
Neither of these insights would have surfaced from a standard survey asking “what do you like about our product.” They came from reconstructing real decisions in detail and finding the pattern underneath them.
How Many Customer Interviews You Actually Need
A common misconception is that positioning-quality insight requires a large sample. According to guidance from customer research platform Mailshake, five to eight well-conducted interviews often reveal more than a 500-response survey built on poorly designed questions, because qualitative depth surfaces the “why” behind a decision in a way quantitative breadth never fully captures.
For Jobs-to-Be-Done research specifically, Bob Moesta’s own guidance, cited across multiple JTBD practitioner sources, suggests interviewing around ten recent buyers with intentional segment coverage, deliberately including people who bought quickly, people who took a long time deciding, and people who almost didn’t buy at all. That range, according to Moesta’s research, tends to reveal three to five distinct buying patterns that together cover roughly 90% of the broader market. Done well, ten to fifteen switch customer interviews reveal the large majority of actionable patterns in a customer base, well short of the hundreds of responses a survey-based approach would assume is necessary.
Don’t Forget Win/Loss Interviews
Switch interviews with people who bought your product tell only half the story. Win/loss interviews, conducted with prospects who either bought from you or chose a competitor instead, according to customer interview research from Koji, are specifically built to understand your competitive position directly, exactly the input the “competitive alternatives” component of positioning depends on.
Interviewing someone who chose a competitor over you is uncomfortable, and it’s also some of the highest-value research a PMM can run. It answers the question a switch interview with your own customers structurally can’t: what made a real prospect, evaluating the same problem, choose differently.
Practical Technique That Applies Regardless of Framework
A handful of interview mechanics matter regardless of which specific framework you’re running, and skipping them undermines even a well-designed switch interview.
Start with a warm-up question grounded in a specific recent moment rather than an abstract one, according to Mailshake’s guidance, something like “walk me through your typical day when you encounter this problem,” before moving into more specific, decision-focused questions.
Talk less than you think you should. A widely cited rule among experienced interviewers: if you’re speaking more than 20% of the time, you’re pitching, not researching. Long, leading questions or eager clarifications from the interviewer are one of the fastest ways to contaminate what should be the customer’s own reconstruction of events.
Close with one open-ended question every time: “is there anything I should have asked but didn’t?” According to Mailshake’s research, this single closing question has surfaced some of the most valuable, unanticipated insight across their own interview practice, precisely because it hands control of the final direction back to the person who actually lived the experience.
And where possible, involve more than just the PMM running the interview. The same trio-based logic covered in product discovery, having more than one perspective present in the room, catches signal a single interviewer working alone is more likely to miss, particularly when the insight touches both product and go-to-market decisions at once.
Turning Interview Findings Into Positioning Inputs
Raw interview notes don’t automatically become positioning insight, they need to be mapped deliberately onto the framework positioning work actually depends on.
For each interview, identify the real competitive alternative the customer was weighing, not the one you assumed going in. Identify the specific push, the frustration that started the search, since this is often the sharpest, most quotable language for a problem statement. Identify what nearly stopped the purchase, the anxiety, since this often reveals an objection your current messaging doesn’t address at all. And look across multiple interviews for the pattern, a single conversation is an anecdote, three or four independent interviews converging on the same push, the same alternative, or the same anxiety is a real signal worth building positioning around.
Common Mistakes That Undermine Interview-Driven Positioning
A handful of mistakes show up repeatedly in interview-based positioning research, and they’re worth naming directly.
Asking about feature preferences instead of reconstructing a real decision is the most common. “What features would you want” produces a wish list disconnected from any real purchase behavior, while “walk me through the last time you dealt with this problem” produces a story grounded in something that actually happened.
Only interviewing happy, retained customers is a close second. A positioning strategy built entirely from your best customers’ feedback misses the churn and loss signal that often reveals the sharpest, most specific objections a broader market actually has.
Talking too much during the interview, correcting a customer’s framing, defending a product decision, or filling silence with a leading follow-up, quietly steers the story toward what the interviewer expects to hear rather than what actually happened.
And treating a single compelling interview as proof of a pattern is a mistake worth naming directly. One vivid story is memorable, but positioning built on an anecdote rather than a pattern across several independent customer interviews is positioning built on a coincidence, not real signal.
And finally…
Positioning depends on understanding a real decision, not a stated preference, and the interviews that actually improve positioning are the ones built to reconstruct that decision in detail: what frustration started the search, what alternative was genuinely on the table, what almost stopped the purchase, and what happened once they committed. Five to ten well-run switch or win/loss interviews, done with real discipline about talking less and asking about specific past events, will surface sharper positioning insight than a much larger, more generic survey ever will.

FAQs on Customer Interviews That Improve Positioning
What’s the best interview technique for improving product positioning?
The switch interview, developed by Bob Moesta and Chris Spiek as part of the Jobs-to-Be-Done framework, is specifically built for this purpose. It reconstructs a customer’s actual decision to switch solutions, revealing the real competitive alternative and the genuine frustration that started their search, exactly the input positioning work depends on.
How many customer interviews do I need to improve positioning?
Five to eight well-conducted interviews often reveal more actionable insight than a much larger survey, according to customer research guidance from Mailshake. For Jobs-to-Be-Done research specifically, around ten interviews with intentional segment coverage tends to surface the majority of distinct buying patterns in a customer base.
What is a switch interview?
A switch interview is a Jobs-to-Be-Done research technique that reconstructs a customer’s actual decision to switch from one solution to another, mapping the timeline from first realizing their current solution wasn’t working through to the final purchase, while also identifying the four forces, push, pull, anxiety, and habit, that drove the decision.
What’s the difference between a switch interview and a win/loss interview?
A switch interview typically reconstructs why an existing customer chose your product, while a win/loss interview specifically targets prospects who evaluated your product and either bought it or chose a competitor instead. Win/loss interviews are particularly valuable for positioning because they reveal your real competitive alternative directly from someone who considered both options.
What questions should I avoid in a positioning-focused customer interview?
Avoid questions that ask for opinions or feature preferences in the abstract, like “what features would you want,” since these produce a wish list disconnected from real behavior. Questions grounded in a specific, recent, real experience, like “walk me through the last time you dealt with this problem,” produce far more reliable and specific insight.
Should I only interview my happiest customers?
No. A positioning strategy built entirely from your best customers’ feedback misses valuable signal from churned customers or lost deals, who often reveal the sharpest, most specific objections and competitive alternatives that happy customers never mention.
How much should I talk during a customer interview?
Honestly, as little as possible. A widely cited rule among experienced interviewers is that if you’re speaking more than 20% of the time, you’re pitching rather than researching, and leading or correcting a customer’s framing during the interview tends to steer their story away from what actually happened.
What question should I always ask at the end of a customer interview?
You can ask: “Is there anything I should have asked but didn’t?”. This single open-ended closing question frequently surfaces valuable, unanticipated insight, since it hands control of the interview’s final direction back to the person who actually lived the experience being discussed.
Can one compelling customer interview be enough to justify a positioning change?
No. A single vivid story is memorable but not necessarily representative. Positioning insight should be built from a pattern that shows up across several independent interviews, not from one anecdote, since one compelling story could just as easily be a coincidence rather than a genuine, widespread pattern.
