# Voice interviews vs one-way video

Both replace the phone screen and let a candidate answer in their own time. What each one asks of the candidate is not the same.

One asks for a recording. The other asks a question and listens to the answer.

## What actually differs

What they do

Voice interview

Has a conversation and answers what is asked next.

One-way video

Records themselves answering questions set in advance.

What they need

Voice interview

A device, and somewhere they can talk.

One-way video

A camera, light, a quiet room, a few uninterrupted minutes.

What it captures

Voice interview

How someone reasons aloud, and what they do when pressed.

One-way video

Presentation, delivery, and how someone comes across on camera.

What it misses

Voice interview

Anything you have to see. A portfolio, a demo, presence.

One-way video

The follow-up. A fixed prompt cannot ask what you meant.

What you do

Voice interview

Reads a scorecard, then the quote behind it.

One-way video

Watches the recordings, or reads a summary of them.

## Where the review time goes

Two hundred applicants at three minutes of video each is ten hours of watching.

A summary is faster than a recording. It is also not the words the candidate said.

Kira-AI returns a band, a 1–5 per criterion with a written anchor, and one or two timestamped quotes.

Nothing reaches the scorecard that Kira-AI cannot point back to in the transcript.

## What a conversation buys

-   ### The follow-up
    
    A thin answer gets one more question, right then, while the candidate is still on the line.
    
-   ### Evidence you can forward
    
    Timestamped quotes against each criterion, not a link to a recording somebody else has to watch.
    
-   ### A lower bar to clear
    
    No camera, no lighting, no quiet room, no video bandwidth. Someone on a break can take part.
    

In a field study of 70,884 call-center applicants, 78% chose an AI voice interviewer over a human one. It also measured 18% more starts and 17% better one-month retention.

## When a one-way video interview fits better

-   The role has to be seen. Sales, presenting, anything performed on camera.
-   You need to see something specific: a portfolio, a demo, a workspace.
-   Your panel wants to review video responses together. Kira-AI provides audio recordings and transcripts, without video.
-   You already score recorded answers against a rubric, and it works. That is not a process worth replacing.
-   You want candidates to re-record. Spark Hire and Willo both allow retakes.

Both formats are async, and plenty of teams run both. Kira-AI does the talking half.
