Remote Interview Best Practices for Qualitative Research

Remote research interviews have gone from a necessary compromise to the dominant format for qualitative research. According to the 2023 State of User Research report by User Interviews, 89% of researchers now conduct the majority of their interviews remotely, up from 62% before 2020. And the data quality concern that initially surrounded remote research has largely been resolved — a comparative study published in the Journal of Computer-Mediated Communication found no statistically significant difference in the depth or thematic richness of data collected in remote versus in-person qualitative interviews (Deakin & Wakefield, 2014).

That said, remote interviews do introduce unique challenges around technology, rapport, and engagement that require deliberate planning to overcome.

Why Remote Interviews Have Become the Default

Remote interviews offer practical advantages that make them the rational choice for most research projects:

The main trade-off is the loss of environmental context. In-person interviews let you observe a participant's workspace, body language, and physical interaction with products. Remote interviews require you to capture this context through questions rather than observation.

Setting Up for Success: Technical Foundations

Audio and Video Quality

Poor audio quality is the number-one technical factor that degrades remote interview data. A study by Stanford researchers found that audio glitches increase cognitive load for both parties and reduce conversational depth by up to 20% (Bailenson, 2021).

Essentials:

• Use a dedicated microphone (even a basic USB mic dramatically outperforms a laptop mic)
• Hardwire your internet connection if possible — Wi-Fi is less reliable for sustained calls
• Close bandwidth-heavy applications before the session
• Use headphones to prevent echo and feedback
• Test your setup with a colleague before your first participant session

Platform Choice

Choose a platform your participants are likely to be familiar with. Introducing unfamiliar tools adds friction and anxiety, which can affect the openness of their responses.

For synchronous video interviews, use the platform your participant pool is most comfortable with. For asynchronous research — where participants respond on their own time — tools like Koji allow you to conduct voice or text-based interviews that participants can complete from any device without scheduling a specific time.

Recording and Consent

Always get explicit consent before recording. Send the consent form before the session and confirm verbally at the start of the call:

"Before we begin, I want to confirm — you received the consent form and you're comfortable with this session being recorded for research purposes? The recording will only be used by our research team."

Building Rapport Remotely

Rapport is harder to build through a screen, but it is not impossible. The first five minutes set the tone for everything that follows.

1. Start With Small Talk (Genuinely)

Ask a natural question about something visible in their environment or something contextually relevant:

• "I see you're working from home — is this your usual workspace?"
• "How has your week been so far?"

2. Share Context About Yourself

A brief personal introduction humanizes you and levels the power dynamic:

• "I'm [name], I work on the research team at [company]. My job is basically to learn from people like you, so there really are no wrong answers here."

3. Set Expectations Early

Participants are more comfortable when they know what to expect:

• "This will take about 30 minutes. I'll ask you some questions about [topic], and I'm genuinely curious about your honest experience — positive or negative."

4. Turn Off Self-View

Research by Bailenson (2021) showed that seeing your own face during video calls increases self-consciousness and fatigue. Turn off your self-view so you can focus entirely on the participant.

Maintaining Engagement During Remote Sessions

The 30-Minute Rule

Remote attention fades faster than in-person attention. Plan your session to cover the most critical topics within the first 30 minutes. If your interview needs to run longer, build in a natural transition point ("We're about halfway through — let me check, are you still comfortable to continue?").

Active Visual Engagement

On video calls, look at the camera (not the participant's face on screen) when you are listening. This creates the perception of eye contact. When speaking, you can shift your gaze to the screen naturally.

Use Screen Sharing Strategically

If you need participants to react to a prototype or document, share your screen rather than sending a link. This keeps control with you and prevents them from getting lost in a tab.

Manage Technical Disruptions Gracefully

When (not if) a connection drops:

• Have a backup communication method ready (phone number or secondary platform)
• Resume with warmth, not frustration: "Welcome back! No worries at all — where were we?"
• Briefly recap what they said before the disruption to show you were listening

Asynchronous Remote Interviews

Not every research interview needs to be synchronous. Asynchronous interviews — where participants respond on their own schedule — offer distinct advantages:

• No scheduling required: Participants respond when it suits them
• More thoughtful responses: People can take time to compose detailed answers
• Larger participant volumes: You can run dozens of interviews simultaneously
• Reduced social desirability bias: Participants feel less pressure to perform

Platforms like Koji facilitate asynchronous research through voice and text-based interviews. Participants receive a link, answer questions at their own pace, and the AI adapts its follow-up questions based on their responses — bringing the probing depth of a live interview to an asynchronous format.

For an inside look at how these work from the participant's perspective, explore voice interview experience and text interview experience.

Common Mistakes to Avoid

1. Skipping the tech check: Testing your setup five minutes before the session is not enough. Do a full test call at least a day before your first session of a study.

2. Multitasking during interviews: Close Slack, email, and all notifications. Participants can tell when you are distracted, even through a screen.

3. Ignoring time zones: Double-confirm the session time and explicitly state the time zone in your calendar invite and confirmation email.

4. Forgetting the recording: Build a checklist that starts with "Hit record." Better yet, use a platform that records automatically with consent.

5. Treating remote as a lesser format: The mindset that remote is "good enough" leads to lower preparation standards. Remote interviews deserve the same rigor as in-person sessions.

Key Takeaways

• 89% of researchers now conduct the majority of interviews remotely, with no measurable quality loss
• Audio quality is the most important technical factor — invest in a decent microphone
• Build rapport in the first five minutes through small talk, context-setting, and clear expectations
• Plan your most critical topics for the first 30 minutes of any session
• Asynchronous interviews expand your reach and can reduce social desirability bias
• Treat remote interviews with the same preparation rigor as in-person sessions

Frequently Asked Questions

Is video always necessary for remote interviews?

No. Video adds body language data and helps with rapport, but audio-only interviews can yield equally rich verbal data. Some participants are more comfortable without video, particularly when discussing sensitive topics. Voice-based asynchronous interviews are another option that removes the scheduling constraint entirely.

How do I handle a participant with a poor internet connection?

Switch to audio-only first. If that does not stabilize the call, offer to continue over a phone call. If neither works, reschedule rather than pushing through — a choppy interview frustrates both parties and degrades data quality.

What is the ideal length for a remote interview?

30 to 45 minutes for most topics. If you need 60 minutes, build in a natural midpoint check-in. Attention drops sharply after 45 minutes in a remote setting, so front-load your most important questions.

Should I send questions to participants in advance?

For most research, no. Sending questions in advance lets participants prepare rehearsed answers rather than responding naturally. The exception is if you need them to gather specific information beforehand (e.g., looking up how they use a particular tool).

How many remote interviews should I conduct per day?

Two to three is a healthy maximum. Interview fatigue is real — your active listening deteriorates after multiple back-to-back sessions. Space interviews at least 30 minutes apart to decompress and jot down initial notes.
