What Interviews Are Good For
User interviews are a qualitative method for understanding:
<ul>
<li>what people are trying to achieve</li>
<li>what gets in their way</li>
<li>how they currently behave</li>
<li>how they describe the problem in their own words</li>
</ul>
Interviews are especially useful when you need to understand why something is happening. They are much less useful for measuring how common something is across an entire population.

Which question is best suited for user interviews?

A well-selected set of 8 to 12 interviews can reveal useful patterns even though it is not statistically representative.

Recruit the Right People
Bad recruiting leads to shallow insights.
A useful interview recruit usually matches the segment you care about and has recently experienced the behavior you want to study.
For example, if you want to improve onboarding, talk to people who recently attempted onboarding. Do not rely only on veteran power users with perfect recall.

Which interview opener is strongest?

Leading questions improve interview quality because they help users get to the point faster.

How to Run Better Interviews
During the conversation:
<ul>
<li>ask about specific past behavior, not vague future intent</li>
<li>let silence do some work</li>
<li>probe for details like “what happened next?”</li>
<li>listen for emotional cues, workarounds, and contradictions</li>
</ul>
A good interviewer talks less than they think they should.

A user says, “I want more AI in the product.” What is the best follow-up?

If three users ask for the same feature, the PM should immediately commit to building it.

Synthesize Before You Decide
After interviews, cluster what you heard into themes.
Separate:
<ul>
<li>observations: what users said or did</li>
<li>interpretations: what you think it means</li>
<li>implications: what product questions or opportunities follow</li>
</ul>
This step matters. Raw quotes are interesting, but synthesis is what turns interviews into product decisions.

Which interview finding is strongest?

Interview notes are more useful when they capture context, exact behaviors, and representative quotes, not just high-level opinions.
