Interview Completion Flow
What happens when an interview ends — thank-you screen, participant feedback, and behind-the-scenes AI analysis.
When a participant finishes their interview, a completion flow kicks in that handles two things simultaneously: giving the participant a satisfying ending, and triggering Koji's analysis pipeline behind the scenes. Here is everything that happens from the moment the conversation wraps up.
How Interviews End
An interview can end in two ways:
Automatic Completion
The AI interviewer tracks which topics from your research brief have been covered and how thoroughly. When it determines that sufficient ground has been covered, it naturally wraps up the conversation — thanking the participant, summarizing the key themes discussed, and saying goodbye.
This is the most common path. The participant does not need to do anything; the conversation flows to a natural conclusion just like a real interview.
Manual Completion (the "Done" Button)
At any point during the interview, participants can click the Done button to end the conversation on their own terms. This is useful when:
- The participant feels they have said everything they want to say
- They need to leave unexpectedly
- They have reached the end of the topics they care about
Whichever method triggers the end, the next step is the same: the participant sees the thank-you screen.
The Thank-You Screen
Once the interview ends, participants are greeted with a celebratory completion screen. Here is what it includes:
Celebration Moment
A brief confetti animation plays when the screen loads, giving participants a moment of delight and a clear signal that they are done. The screen displays a large, friendly "All Done!" message, personalized with the participant's name if it was collected.
Thank-You Message
Below the celebration, the AI interviewer's avatar appears with a thank-you message. It acknowledges the participant's time and effort, creating a warm, human-like conclusion to the experience.
If the interview captured the participant's name (through an intake form or CSV import), the message is personalized — for example, "All Done, Jane!"
Interview Duration
The completion screen shows how long the interview lasted, formatted as a friendly duration (e.g., "5 minutes" or "Less than a minute"). This gives participants a concrete sense of their contribution.
Participant Feedback
After the thank-you message, participants are invited to rate their experience. The feedback collection includes:
Rating Scale
A five-point emoji scale from "Poor" to "Amazing" lets participants quickly indicate how they felt about the interview. The options are:
- Poor
- Okay
- Good
- Great
- Amazing
Participants tap their rating, and the selection is highlighted visually.
Written Feedback (Optional)
Below the rating, a text area invites participants to share additional thoughts. This is completely optional — many participants will select a rating and move on, while others will write a sentence or two.
Submitting Feedback
A submit button appears once a rating is selected. After submission, the participant sees a confirmation message thanking them for the feedback.
Feedback is not mandatory. If a participant closes the tab without submitting feedback, the interview is still recorded as completed and the analysis still runs.
What Happens Behind the Scenes
While the participant is looking at the thank-you screen, Koji's analysis pipeline is already running in the background. Here is what happens automatically:
Transcript Processing
The full conversation — whether it was conducted via voice or text — is processed into a clean text transcript. For voice interviews, the audio is transcribed. For text interviews, the messages are already in text form.
Quality Scoring
Koji's quality evaluation assigns a score from 0 to 5 to the interview. This score reflects the depth, relevance, and informativeness of the participant's responses relative to your research brief.
- Score 3 and above: The interview counts toward your study and contributes meaningful data.
- Score below 3: The interview is flagged as low quality. It does not count toward your plan's interview limits, and you are not billed for it.
This quality gate ensures you only pay for interviews that actually deliver value. Learn more in Understanding Quality Scores.
AI-Generated Insights
After scoring, Koji analyzes the transcript to extract:
- Key themes discussed during the interview
- Notable quotes that capture important sentiments
- A summary of the participant's main points
- Sentiment indicators for different topics
These insights appear on the interview detail page in your dashboard and contribute to the project-level analysis. See AI-Generated Insights for a deep dive into what gets generated.
Analysis Timing
The analysis typically completes within a few minutes of the interview ending. You will see the results appear in your project dashboard as they become available. Voice interviews may take slightly longer due to the additional transcription step.
What the Researcher Sees
Back in your project dashboard, completed interviews show up with:
- A status badge indicating the interview is complete
- The quality score (0-5)
- The participant's name (if collected)
- Message count and duration
- A link to the full transcript and analysis
You can click into any completed interview to read the transcript, review the quality score breakdown, and see the AI-generated insights.
Handling Abandoned Interviews
Sometimes participants start an interview but close the browser before finishing. Koji handles this gracefully:
- The conversation is saved up to the point where the participant left
- After a period of inactivity, the interview is marked as abandoned
- Abandoned interviews are still analyzed if they contain enough content to be meaningful
- They appear in your dashboard with an appropriate status indicator
Feedback Data for Researchers
The ratings and written feedback that participants submit on the completion screen are stored alongside the interview record. You can use this data to:
- Monitor participant satisfaction across your study
- Identify issues with specific interview topics or questions
- Improve future studies based on what participants did and did not enjoy
Feedback ratings and comments are visible in the interview detail view and can be included in exports.
Customizing the Completion Experience
Currently, the thank-you screen uses a standard layout and messaging. The AI interviewer's name that was used during the conversation is reflected in the completion message, maintaining consistency.
If your interview is embedded via the embed widget, the completion screen renders inside the iframe. You can listen for the koji:interview_completed event to trigger your own follow-up actions on the parent page — such as showing a discount code, redirecting to another URL, or logging the completion in your analytics.
