Structured Interviews: Configuration and Best Practices

A Structured Interview on Qualz.ai follows a rigid, scripted format where every question is asked exactly as written, in a fixed order, with no improvisation or probing. This guide explains how to configure a structured interview, what happens behind the scenes, and best practices for getting the most out of this mode.

What Makes a Structured Interview Different?

In a structured interview, the AI moderator behaves like a disciplined human interviewer following a precise script:

Questions are asked verbatim — The AI does not rephrase, paraphrase, or modify any question
No probing or follow-up questions — After the participant responds, the AI gives a brief acknowledgment and moves to the next question
Fixed question order — Questions are asked sequentially as they appear in your interview guide
No improvisation — The AI will not introduce new questions or explore tangents, even if the participant's response opens an interesting thread
Explicit stimulus display — If a stimulus image is assigned to a question, it is shown when that question is asked

This makes structured interviews ideal for studies where consistency and comparability across participants are paramount.

How to Set Up a Structured Interview

Step 1: Select Structured Interview Mode

During the interview creation process, select Structured from the Interview Mode cards. This controls both how your guide is structured and how the AI moderator behaves during the interview.

Step 2: Build Your Interview Guide

You have three ways to create your interview guide:

Option A: Generate with AI Click the Generate with AI button. The AI creates a set of standalone questions organized by topic that fit within your selected time limit:

5-minute interview: 3-5 questions
10-minute interview: 5-8 questions
15-minute interview: 8-12 questions
30+ minute interview: 12-18 questions (maximum)

The generated questions follow a logical progression, starting with introductory topics and building toward more specific areas aligned with your study objectives.

Option B: Add Questions Manually Click Add Question to create items one at a time. Type your question text directly into the card — it supports inline editing.

Option C: Paste an Existing Guide Click Paste existing guide, paste your freeform text, and click Structure pasted guide. The AI converts it into individual question cards.

Step 3: Refine Your Guide

Each question appears as a card in the guide editor. You can:

Drag to reorder — Use the handle on the left to change question sequence
Edit inline — Click the question text to modify it directly
Assign stimulus — Click the image icon to attach a stimulus image from your uploaded materials
Delete — Remove questions that don't fit

Since the AI will ask questions exactly as written, take care to:

Write clear, single-focus questions (avoid double-barreled questions)
Order them in a logical conversational flow
Keep each question concise enough for verbal delivery

Step 4: Set Duration and Buffer

Select your interview duration (5-60 minutes) and optionally add an overflow buffer (+5, +10, or +15 minutes) for extra time if the conversation runs long.

How the AI Moderator Runs a Structured Interview

Opening

The AI introduces itself using your configured AI interviewer name (default: "Qualz AI Interviewer"), briefly explains the format, and immediately asks the first question from your guide.

During the Interview

For each question, the AI follows this pattern:

Displays any assigned stimulus image
Asks the question exactly as written in the guide
Listens to the participant's full response
Gives a brief, varied acknowledgment (e.g., "I see," "Thank you," "That makes sense")
Moves promptly to the next question

The AI will not:

Ask follow-up questions or probes
Rephrase questions if the participant doesn't understand (it will re-read the original question if asked to clarify)
Skip questions based on previous answers
Add questions that aren't in the guide

Closing

After the final question is answered (or the participant chooses to end), the AI thanks them sincerely and concludes the session.

When to Use Structured Interviews

Ideal scenarios:

Comparative studies where you need identical questions across all participants to enable direct comparison
Regulatory or compliance research where the exact wording of questions matters
Large-scale studies (50+ participants) where consistency trumps depth
Baseline data collection before running more exploratory follow-up interviews
Sensitive topics with legal implications where precise question wording has been pre-approved

Consider a different mode when:

You want to explore unexpected themes that emerge during conversation — try Semi-Structured
You're in early-stage research and don't yet know the right questions — try Unstructured
You want participants to lead the conversation — try Unstructured

Best Practices

Pilot test your questions — Since the AI won't improvise, unclear questions will produce poor responses. Use AI Participants to pilot test before launching with real participants.
Front-load important questions — If a participant runs out of time or ends early, your most critical questions should be at the top. Use drag-to-reorder to prioritize.
Write conversational questions — Even though the AI reads them verbatim, questions should sound natural when spoken aloud. Avoid academic or overly formal phrasing.
Match question count to time limit — Allow 1-2 minutes per question. Too many questions will rush the interview; too few will leave dead time.
Use stimulus for visual research — Assign product mockups, ad concepts, or other visuals directly to questions so they appear at the right moment. See the Stimulus Images in Interviews guide for a full walkthrough.
Use the Additional Instructions field — Add context that helps the AI moderator without changing the questions. For example: "This study focuses on enterprise users in the healthcare industry."
