What this method settles

Commission this when one of the questions below is holding up a decision. If your question is not on the list, say so in the brief — we would rather recommend a different method than sell you this one.

What actually happened, step by step, the last time someone bought this?
What do people say about money, health or status that they would never say in a group?
Which influences inside the household or the firm changed the final choice?
What would a sceptic need to believe before switching to us?
Where does the real journey diverge from the journey our funnel assumes?

How we run it

5 stages, with one research director accountable across all of them. The person who scopes the study is the person who presents the findings.

1
Choose depth over breadth deliberately
We agree which three or four segments genuinely need separate hearing, then set a quota per segment rather than one undifferentiated total.
2
Recruit for recency
Respondents are screened on how recently they made the decision, because reconstructed memory from two years ago is not evidence.
3
Interview with laddering
Interviewers work from behaviour to reason to underlying value, so you get motivation rather than the rationalisation offered first.
4
Transcribe and code
Every interview is transcribed in full and coded against a framework built from the first five, then refined as the fieldwork runs.
5
Build personas from cases
Personas are assembled from real interviews with the quotes attached, so your team can see who each one came from.

In-Depth Interviews — typical study parameters

Typical scale: 15 to 40 interviews of 45 to 90 minutes, split across the segments you need to hear separately
Fieldwork window: Two to four weeks, longer for hard-to-reach specialists
Lead time: First interviews within seven working days for consumer audiences
Coverage: Face to face in 50 cities, telephonic and video for dispersed or senior respondents
Languages: Conducted in the respondent's own language, transcribed with the source verbatim retained
Core methods: Face-to-face IDIs · Telephonic IDIs · Expert interviews · Paired depths
Reporting: Transcripts, a coded thematic analysis and persona profiles grounded in real cases
Best suited to: Private, sensitive or highly individual decisions

What you receive

3 named deliverables, each written to be used rather than filed. Everything ships with the underlying data, so your team can keep working after the debrief.

Transcripts
Full transcripts in the original language and English, searchable and tied to the respondent screening record.
Thematic analysis
A coded thematic framework showing which motivations recurred, which were isolated, and where segments genuinely differ.
Persona profiles
Three to five personas built from actual cases, each with the trigger, the barrier and the message that works.

What keeps the data honest

Fieldwork in India fails quietly when nobody checks it. These controls are run on every in-depth interviews study, by a quality team that reports separately from the field team.

Two-pass recruitment screening
Respondents are screened by phone against the quota grid, then re-screened on arrival. Category usage and articulation are both checked, and substitutes are kept on standby.
No professional respondents
A national exclusion list blocks anyone who has taken part in a session in the last six months, or in three sessions over two years.
One senior moderator across the study
The same moderator runs every session, so differences between cities are differences in the market rather than in moderation style.
Verbatim kept in the original language
Sessions are recorded, transcribed and translated with the source-language verbatim preserved alongside the English, so nuance survives the handover.
Interviewer calibration before fielding
All interviewers run a pilot that is reviewed together, so probing depth is consistent and the fifteenth interview is as good as the first.

Method choice

In-Depth Interviews, or one of these instead?

Most briefs can be answered more than one way, and the wrong instrument is the most expensive mistake in research. Here is how in-depth interviews compares with the two methods buyers most often weigh against it.

	In-Depth Interviews	Focus Group Discussions	Ethnographic Research
Best used for	Private, sensitive or highly individual decisions	Hearing a category argued out between real users	Seeing what people do rather than what they report
Typical scale	15–40 interviews	6–12 groups	12–30 immersions
Fieldwork window	2–4 weeks	2–3 weeks	4–6 weeks
Evidence produced	A full decision story from one person at a time	Language, reactions and the reasoning behind them	Observed behaviour in its real context
Projects to a population
Relative cost	Moderate	Moderate	High per household, small base

Where this method stops

Not the tool when group dynamics are the point, or when you need a number you can defend to a board.

City coverage

Where this work is strongest

We field in all 50 cities, but these are the markets where this method has the most to offer — because of the infrastructure, the respondent base or the sectors concentrated there.

Frequently asked questions

How long does a in-depth interviews project take?

Two to four weeks, longer for hard-to-reach specialists. First interviews within seven working days for consumer audiences. Analysis and reporting add a further one to two weeks, so most studies close inside six to ten weeks from brief to debrief.

What sample size do you recommend?

15 to 40 interviews of 45 to 90 minutes, split across the segments you need to hear separately. The right number is set by the smallest subgroup you need to report separately, not by a round figure, and we will say when a smaller sample would answer the question just as well.

What drives the cost of in-depth interviews in India?

Incidence and audience difficulty first, then scale, the number of cities and languages, and the depth of reporting. Relative to other methods on this site, the cost profile is: moderate. Send a brief and you get a fixed-fee proposal within 24 hours.

When is in-depth interviews the wrong choice?

Not the tool when group dynamics are the point, or when you need a number you can defend to a board.

How do you control quality in the field?

Respondents are screened by phone against the quota grid, then re-screened on arrival. Category usage and articulation are both checked, and substitutes are kept on standby. Beyond that, interviewer calibration before fielding: all interviewers run a pilot that is reviewed together, so probing depth is consistent and the fifteenth interview is as good as the first.

Can international teams commission this from outside India?

Yes. We report in English, run calls across US, European and Asian time zones, and handle local-language fieldwork and translation end to end.
