What goes wrong

Common mistakes in in-depth interviews

Most disappointing in-depth interviews studies fail for reasons that were visible in the design, not in the fieldwork. These are the ones we see most often, and what to do instead.

01
Questions that carry their own answer
“What do you dislike about the service?” presumes dislike. Ask what happened last time, then follow the story rather than the hypothesis.
02
Accepting the first answer
The first response is a rationalisation. Laddering — asking why that matters, three or four times — is what separates a depth interview from a long survey.
03
Recruiting everyone from one source
Twenty-five interviews all sourced from a single customer list describe that list, not the market. Use at least two independent recruitment routes.
04
Counting mentions as if they were data
“14 of 25 said” lends a qualitative sample the authority of a survey it has not earned. Report themes and their reasoning, and quantify separately if you need numbers.
05
Regional language nuance lost in translation
Category language in Hindi, Tamil or Marathi rarely survives live translation. Work in the respondent's language and translate the transcript, not the conversation.
06
Verbatims presented as findings
A deck of quotes is evidence, not a conclusion. Code to themes, note how widely each appears, and write the implication for the decision beside it.

Run through this before sign-off

Your checklist before you brief anyone

A working sequence for a in-depth interviews project. Most of it costs nothing, and it saves the two weeks a re-field would take.

1
Write the screener before the discussion guide; who you talk to decides more than what you ask.
2
Pilot two interviews and rewrite the guide before the rest are scheduled.
3
Record and transcribe with explicit consent, and keep the recording in the interview language.
4
Ladder every important answer with “and why does that matter to you?” at least twice.
5
Code to a shared framework, so two analysts reading one transcript reach the same themes.
6
Record and transcribe in the respondent's own language, with consent captured in writing.
7
Agree in writing who acts on each finding, and by when, before the debrief ends.
