An AI video interview assistant does different things depending on which of two formats you face: in a live video call with a human interviewer on Zoom, Teams or Meet, it can listen to the conversation and suggest answers in real time, if the employer allows that; in a recorded one-way video interview, where you answer timed questions on camera with nobody present, it is a rehearsal tool, because those rounds are usually proctored and your eyes are on camera. Confusing the two is the most common mistake people make with these tools. This page separates them, covers camera and eye-line for each, and gives a practice routine that serves both.
Two formats, two uses
| Live video call | Recorded one-way interview | |
|---|---|---|
| Who is there | A human interviewer | Nobody; recruiters watch later |
| Questions | Conversational, with follow-ups | Fixed, timed, often no retake |
| Proctoring | Rare | Common: tab switching, eye tracking in some platforms |
| Assistant's role | Live prompts, if allowed | Rehearsal before, review after |
| Biggest risk | Sounding scripted | Reading from another screen on camera |
The recorded format is explained in what is a one-way video interview; the live setup is on our video interview assistant page.
Camera and eye-line
- Camera at eye level, light in front of you, background plain.
- In a live call, if you use an assistant, position its window directly under the camera so glances stay near the lens; a wide sideways window is obvious.
- In a recorded interview, close everything else; the platform may log it and your eyes will show it.
- Look at the lens when making your main point, at the screen the rest of the time; constant lens-staring looks odd too.
- Test the setup with a recorded practice answer and watch it back once.
Why recorded rounds are rehearsal-only
One-way platforms record your face for the whole answer and some analyze attention; many log tab switches and window focus; most forbid outside help in the terms you accept when you start. Reading an answer from another window shows in your eyes even when nothing is logged. Treat the round as a performance: the assistant's job is to generate the likely questions, time you, score you and show a model answer until the real thing feels routine. Preparation specifics are in how to practice for a video interview.
A routine that serves both
- Run a mock interview from the job description with the camera on, as if recording.
- Watch one answer back; fix the two things that bother you most.
- Rehearse answers to 60 to 90 seconds; both formats punish rambling.
- For a live call, decide in advance whether live prompts are appropriate for this employer; if yes, set them to short points.
- For a recorded round, do the platform's practice question, then record unaided.

Where CoPilot Interview fits
CoPilot Interview is an AI interview assistant for Windows and macOS that runs as a separate window beside your video call, listens to the call and your microphone, and shows a structured answer in about two seconds; the free AI mock interview rehearses with questions read aloud and scores out of ten, which is the right tool for the recorded format. The free plan gives 15 minutes a day of live help in sessions of up to 15 minutes, with AI mock interviews included. In a live call, speak your own words and follow your employer's rules; in a recorded round, practice beforehand and record alone.

Frequently asked questions
What does an AI video interview assistant do?
In a live video call it can listen and suggest answers in real time, where allowed. In a recorded one-way interview it is a rehearsal tool, because those rounds are proctored and your eyes are on camera.
Can I use an AI assistant in a one-way video interview?
Not during recording: platforms log focus changes and your eyes show it. Use it to practice the questions and timing beforehand.
Where should the assistant window go in a live video call?
Directly under the camera, narrow, so glances stay near the lens. A wide sideways window is obvious.
How long should video interview answers be?
Sixty to ninety seconds. Both live and recorded formats punish rambling, and recorded ones cut you off.
Is the mock interview free?
Yes. CoPilot Interview's AI mock interview is included on the free plan, with questions generated from your résumé and the job description.
