I have been on the interviewer side of enough video calls to know something uncomfortable: the setup changes how the answers land.
Not because anyone consciously judges your webcam. Because a candidate who is echoing, backlit, and framed from the chin up is genuinely harder to follow — and effort spent following you is effort not spent being impressed by you.
None of this requires equipment. Most of it is free.
Audio is the one that matters
If you fix exactly one thing, fix audio.
Video problems are annoying. Audio problems are disqualifying, because they make people ask you to repeat yourself, and repetition kills the rhythm of an answer no matter how good it was.
In order of impact:
| Fix | Why |
|---|---|
| Wired earbuds with a mic | Beats a laptop mic and cannot drop out like Bluetooth. Cheapest upgrade available. |
| Headphones of any kind | Eliminates echo. Without them, your speaker feeds back into your mic. |
| A soft room | Hard walls and bare floors produce reverb. Curtains, a rug, a bed nearby — all help. |
| Silence the room | Phone on silent, notifications off, fan off if it hums, door closed. |
Bluetooth earbuds are a genuine risk. They drop, they run out of battery mid-round, and they sometimes switch to low-quality mode the instant you speak. Wired removes all three failure modes.
Light comes from in front
The most common mistake is a window behind you. The camera exposes for the bright background, and you become a silhouette.
Turn around. Face the window. If it is an evening call, put a lamp behind your laptop pointing at you — not overhead, which casts shadows down your face.
Test it by starting a call with yourself and looking at the preview. If you can see your eyes clearly, it is fine. That is the whole standard.
Camera at eye level
Laptop on a desk means the camera looks up at you. It is an unflattering angle and it subtly reads as looking down at the other person.
Raise the laptop until the camera is level with your eyes. A stack of books works. This is a five-second fix that most people never make.
For framing: head and shoulders, with a little space above your head. Not just your face filling the frame, not your whole torso from across the room. Enough that hand gestures are visible when you use them — gesture carries a surprising amount of your energy and it is lost if you are cropped too tight.
The eye contact problem
Here is the one nobody mentions.
When you look at the interviewer's face on screen, you are looking below your camera. To them, you appear to be looking down or away. When you look at the lens, you make eye contact with them — but you cannot see their reactions.
You cannot have both. The workable compromise:
- Look at the lens when you are making an important point — the start of an answer, the punchline of a story.
- Look at their face the rest of the time, especially while listening. Moving the video window to the top of your screen, as close to the camera as possible, shrinks the angle and makes the difference less visible.
Also: turn off self-view if your platform allows it. Watching yourself is a live distraction, and it makes people perform rather than talk.
Background and dress
Background: tidy, not staged. A plain wall is perfectly fine. A shelf is fine. What is not fine is a virtual background that clips your head every time you gesture — that is more distracting than any real room.
Dress: whatever the company's own team would wear, one small notch up. Solid colours read better on camera than fine patterns, which can shimmer.
And wear real clothes on the bottom half. Not for them — for you. People sit differently when they are fully dressed, and it shows in posture.
Where to put your notes
The genuine advantage of a video interview: you can have notes and nobody knows.
The way to waste that advantage is to put them somewhere that makes you obviously look away.
- Sticky notes around the camera — a glance is invisible.
- A second window directly under the camera — small, few words, keywords only.
- Not a document on a second monitor that makes your eyes travel sideways. Keywords, never sentences. If your notes are readable prose you will start reading them, and reading aloud sounds exactly like reading aloud.
The fifteen-minute checklist
Run this before every call:
- Join a test call — check camera, mic, and speakers on the actual platform being used
- Close every application that might notify, especially messaging apps
- Phone on silent, face down, out of reach
- Water within arm's reach
- Job description and notes positioned under the camera
- Tell anyone in the house
- Have the interviewer's phone number or email open, in case the link fails
- Join two minutes early Point seven is the one people skip and then regret. Links fail. Platforms crash. If you can send "Zoom isn't loading on my end — trying again, or I can call" within thirty seconds, a technical failure becomes a non-event. If you cannot, you sit there while the interviewer waits.
Once the setup is invisible
Good setup does not win you anything. It just stops you losing something for a reason unrelated to your ability — which is the same logic behind every other item on my pre-interview checklist.
With the mechanics handled, what remains is the conversation: structure, pacing, and not talking for four minutes when ninety seconds was the right length. That is the part worth practising.
