Video interview setup: audio, camera, and a rehearsal-ready environment
Fix audio first: a quiet room, earphones, and a tested microphone matter more than video quality. Put the camera at eye level with light in front of you, remove interruptions and background distractions, keep notes at screen height, and rehearse in the same setup you will use for the real call.

Fix audio before anything else
Interviewers tolerate mediocre video far better than mediocre audio. If they have to work to hear you, every answer costs more attention than it should. A quiet room, a stable connection, and a microphone that does not echo or clip matter more than camera quality, background styling, or what you wear below the frame.
Use the microphone you will actually use on the day and test it by speaking a full answer, not just saying a few words. Headphones or earphones prevent the interviewer's voice from feeding back into your microphone. Avoid rooms with hard bare walls if your voice echoes, and close windows against traffic noise you have stopped noticing.
- Test the real microphone with a full spoken answer, not a check-one-two.
- Use earphones to prevent echo of the interviewer's voice.
- Choose a small or furnished room over a large empty one.
- Silence fans, notifications, and other audio sources in the room.
Position the camera and light for the conversation
Place the camera at roughly eye level so the conversation feels like it is across a desk. A laptop on a stack of books is fine; a camera pointing up from the desk is not. Put the light source in front of you, not behind you. A window or lamp behind you turns you into a silhouette no matter how good the camera is.
Framing should show your head and shoulders with a little space above your head. Check what is visible behind you for things you would rather not explain: confidential papers, a second screen, or housemates moving through the shot. A plain wall is easier than managing a busy room.
- Camera at eye level, head and shoulders in frame.
- Light in front of you, not behind you.
- Check the visible background for anything confidential or distracting.
- Use the setup you already have before buying anything.
Remove the interruptions you can control
Close every application you do not need, then disable notifications system-wide, not just in the app you remember. A screen-share or a glance at a notification is a small break in eye contact that the interviewer can see. If you might share your screen, clean up your desktop, tabs, and downloads folder names beforehand.
Tell the people you live with when the call is, and have a fallback ready: a phone number for the interviewer, a charged phone, and a mobile hotspot if your connection is unreliable. You cannot remove every risk, but having a plan means an interruption costs a minute instead of the interview.
Place notes where they do not look like reading
Notes are acceptable in most interviews and expected in some; being visibly glued to a script is the problem. Keep notes to a small set of prompts such as your examples, your questions, and the job description. Put them at screen height near the camera so glancing at them looks like looking at the interviewer rather than down at a desk.
Prepare them as reminders, not sentences to read. A few bullet points survive a nervous moment; a paragraph you planned to recite will make you sound rehearsed and will fail the moment the question shifts. If the employer has told you notes are not allowed, respect that and practise without them. The body-language guide covers eye contact, posture, and notes on camera in more detail.
Rehearse in the same setup you will interview in
The value of a practice call is partly that it surfaces setup problems while they are still cheap. If you practise on a laptop on your bed and interview at a desk with an external monitor, you are rehearsing a different physical situation: different camera height, different microphone, different posture, and different notes position.
Run at least one full spoken rehearsal in the real configuration. In PrepRole, Candidate video stays in the browser, and a camera check on your device flags a dark or backlit face, poor framing, or another person in view before the AI Interviewer joins. If you turn on Delivery Signals (Beta) in a Recruiter Screen, Behavioral, or Hiring Manager session, your browser also estimates where you looked, how steady your head stayed, and how loudly you spoke during each answer, and only those approximate numbers are saved with your Scorecard. The session itself shows things a text rehearsal cannot: whether your answers hold together when spoken, and whether the notes you placed near the camera help or distract you. Treat the camera check as a setup aid, not a judgement about your appearance or ability.
A short checklist for the day of the call
On the day, repeat the checks rather than assuming last week's setup survived. Join a few minutes early if the platform allows it, but do not join so early that you sit anxiously in a waiting room. If something breaks during the call, say it plainly and switch to your fallback; interviewers reschedule around honest technical problems more often than candidates expect.
- Test microphone, camera, and connection again on the day.
- Close unneeded applications and silence notifications.
- Place notes, water, and the job description within reach.
- Have the fallback ready: phone number, charged phone, hotspot.
- Check the link, time zone, and the interviewer's name one last time.
Frequently asked questions
Do I need an external microphone or camera?
Usually no. A quiet room, earphones, and good light improve a call more than equipment upgrades. Only buy hardware if a test recording shows a real problem your current setup cannot fix.
Should I use a virtual background?
Only if your real background shows something confidential or genuinely distracting. Virtual backgrounds can clip around your head and add a layer of artificiality. A tidy real wall is usually better.
Should I look at the camera or the screen?
Look at the screen while listening; glance at the camera when making a key point, since that reads as eye contact. Positioning the interview window near the camera makes the difference smaller.
What if my connection fails during the interview?
Say it plainly, reconnect, and use your fallback such as a phone number or hotspot. Have the interviewer's contact details accessible outside the meeting link. A handled failure looks far better than pretending a frozen screen did not happen.
Practise the next answer
Run a Mock Session in the same setup you will use for the real call: same device, microphone, camera position, and room. PrepRole keeps Candidate video in the browser. Before the AI Interviewer joins, a camera check on your device points out framing and lighting problems, so rehearsing in your real environment catches them early.
