How to Ace a Video Job Interview: 8 Mistakes Candidates Still Make

Video interviews are everywhere now. Zoom, Teams, Google Meet — the platform doesn't matter. What matters is that most candidates still prepare as if they were walking into an office and forget everything that's different about being on screen.

The result: wandering eye contact, poor audio, distracting backgrounds, and an energy level that doesn't translate through a webcam.

A video interview requires its own kind of preparation. Here are the 8 most common mistakes — and how to fix each one.

Mistake 1: Looking at the Screen Instead of the Camera

This is the most widespread mistake and the hardest to break. When you look at the interviewer's face on your screen, your gaze appears slightly lowered on their end. To them, it looks like you're staring at something below — not making eye contact.

Real eye contact in a video call means looking at the camera lens, not the screen. It feels unnatural, but it's what creates the impression of direct connection.

A simple trick: stick a small colored dot or a tiny post-it right next to your camera lens. It gives you a visual anchor to look toward when you're speaking. When the interviewer is talking, you can look at the screen — it's your own speaking moments where the camera gaze counts most.

Mistake 2: Ignoring Audio Quality

Candidates think about how they look. Almost nobody thinks about how they sound — even though audio is what determines whether the interviewer listens comfortably or struggles to understand you for 45 minutes.

Your laptop's built-in microphone picks up everything: the fan, street noise, room echo. A headset with a built-in mic — even a basic pair of earbuds — dramatically improves clarity.

Test your audio before the interview. Not on the day: the day before. Record yourself for 30 seconds using the same platform you'll be on. Play it back. If your voice sounds distant or muffled, switch microphones or bring yours closer.

Close the windows. Mute notifications. Tell the people around you. The silence of your environment is part of your preparation.

Mistake 3: A Background That Tells the Wrong Story

A plain wall is fine. A tidy bookshelf works well. But an unmade bed in the frame, a cluttered room, or a virtual background that pixelates every time you move sends a clear signal: you didn't take the time to set up your space.

Your background is part of the first impression. The interviewer sees it before you say a word.

If you don't have a clean space, a solid-color virtual background (not a tropical beach) is better than a messy real one. But a real background, even a simple one, always looks more professional than a virtual one — as long as it's tidy.

Mistake 4: Lighting That Makes You Disappear

If the light source is behind you — a window at your back, for instance — your face appears in shadow. The interviewer sees a dark silhouette. Your expressions, your smiles, your reactions: invisible.

The main light source should be in front of you, not behind. A window facing you is ideal. Otherwise, a desk lamp positioned behind your screen, pointed toward your face, does the job.

No need for a professional ring light. Just a light that illuminates your face evenly, without harsh shadows on one side.

Mistake 5: Framing Too Close or Too Far

A face filling the entire screen feels overwhelming. A wide shot where you're visible from the waist up, sitting deep in your chair, makes you seem distant.

The right framing for a video interview: from the top of your head to mid-chest, with a bit of space above. This recreates the natural distance of a face-to-face conversation.

Position your camera at eye level. If you're using a laptop on a desk, the camera is too low — you'll appear from below, which distorts your face and creates an unintentionally dominating angle. Stack a few books under your laptop to bring the camera in line with your eyes.

Mistake 6: Forgetting to Bring Energy to Your Face

In person, your energy comes through your whole body: your posture, your gestures, the way you lean forward slightly when something interests you.

On video, the interviewer only sees your face and shoulders. Everything below the frame is invisible. That means your face has to carry all the expression.

Candidates who keep a neutral face for 30 minutes come across as disengaged — even if they're genuinely interested. Nod when the interviewer speaks. Smile when it's appropriate. Vary your expressions. This isn't overacting — it's compensating for the information loss that the camera creates.

Avoid rocking in your chair or constantly touching your face. On screen, these movements are amplified and quickly become distracting.

Mistake 7: Not Preparing for Technical Problems

The connection drops. The screen freezes. The audio crackles. It happens to everyone. What sets you apart is how you react.

Before the interview: test your connection on the same network, with the same tool, at a similar time of day. If your Wi-Fi is unreliable, plug in an Ethernet cable. Close unnecessary tabs and bandwidth-heavy applications.

Have a backup plan. Keep the interviewer's phone number or email address within reach so you can flag an issue immediately. If the call drops, send a message within 30 seconds: "I'm experiencing a technical issue — reconnecting now." The speed of your response shows composure — which is itself a positive signal for the interviewer.

Join the call 5 minutes before the scheduled time. Not 15 (that puts pressure on the interviewer), not 1 (that leaves no margin).

Mistake 8: Reading Notes on Screen

The advantage of a video interview is that you can keep notes nearby. The trap is reading them.

The interviewer notices immediately. Your eyes scan across the screen, your speech becomes mechanical, your tone loses its natural rhythm. What was supposed to be a safety net becomes a liability.

Notes in a video interview should be landmarks, not a script. A few keywords on a post-it stuck near your camera. The interviewer's name. Two or three points you absolutely want to cover. That's it.

If you need to read your answer, it means you haven't practiced it enough beforehand. The solution isn't to hide your notes better — it's to train yourself to answer out loud before the day comes.

What Doesn't Change Between Video and In-Person

The substance stays the same. The quality of your answers, the coherence of your career story, your ability to explain what you bring to the table — none of that changes because you're behind a screen.

What changes is the delivery. The way the message lands. And on video, delivery depends on technical details that many candidates overlook: audio, lighting, eye contact, framing, facial energy.

Getting these details right doesn't guarantee you'll land the job. But ignoring them can be enough to eliminate you — before the interviewer has even assessed your skills.

The best way to prepare for a video interview is to practice in the same conditions. Not by re-reading notes. By speaking, facing a camera, and hearing how it sounds.
