PM User Interviews
(2026 Edition)
Good user interviews ask about past behavior instead of hypothetical futures, favor observation over stated preference, and keep interviewers listening roughly 70% of the time — with one interviewer and one note-taker per session to split cognitive load. Skipping synthesis is the most common trap: raw notes rot and themes decay, which is why five interviews a month is the baseline habit.

Ask about past behaviour, not hypothetical futures — 'show me the last time' > 'would you'
Shut up — target 70% listening, 30% asking
'Why?' five times — surface-level answers hide the real driver
Observe, don't ask — watching beats asking about UX every time
One interviewer, one note-taker — split cognitive load
Sample size 5 per segment — you'll hear the pattern; more is diminishing returns
4 Traps
Leading questions — 'don't you think this would be great?'
Accepting stated preference over observed behaviour
Interviewing only power users — blind spot for the mainstream
No synthesis — raw notes rot; themes decay; decisions suffer
FAQ
How often should PMs interview users?
Minimum: 5 interviews per month as a baseline habit. More during discovery or major rework. PMs who go months without talking to users develop polished but wrong mental models. Interview hygiene is like code review — skip it, and quality rots silently.
