The camera
Aarav's first online interview: laptop on the bed, screen tilted up, one tube light behind his head. Priya spent 28 minutes talking to a dark shape with a fan turning above it. She never once saw his eyes.
Lens for the first and last sentence of every answer.
The light goes in front
One rule covers ninety per cent of it: the brightest thing in the room must be in front of your face, never behind your head. A window behind you turns you into a black cut-out, because the camera adjusts for the bright window and gives up on you.
Never: a window behind you, a tube light directly overhead, or a lamp beside the screen that lights half your face and leaves the other half dark.
Bad audio ends interviews
People forgive a dark room. Nobody forgives audio they have to strain through. Three rounds of "sorry, could you repeat that?" and the interviewer quietly stops asking follow-up questions.
Sits 50 cm away and records the whole room equally: the fan, the echo, your keyboard, the street. Your voice is one sound among five.
The mic hangs 20 cm from your mouth, so your voice is far louder than the room. Earphones also stop their voice leaking back into your mic, which is what causes echo.
Play it back on speaker and listen for four things: the fan, echo, traffic, and whether your voice is too soft. Then pick the device: Meet → Settings → Audio; Zoom → Audio → Test Mic; Teams → Settings → Devices → Make a test call.
A plain wall beats everything
A plain wall one metre behind you beats every virtual background ever made. It never glitches, it uses no CPU, and it keeps all the attention on your face. If your room has one blank wall, that is where you sit.
When virtual backgrounds glitch
- Low light. The software guesses your edges from the picture; in a dim room it guesses wrong and your ear disappears.
- Your shirt is the same colour as the wall behind you. Half your shoulder vanishes every time you move.
- An older or 4 GB laptop. Blur eats CPU, video starts stuttering, and choppy video is far worse than a visible bed.
- You talk with your hands. Hands are fast and thin, so they flicker in and out of the frame.
Order of preference: real plain wall, then light blur, then an ironed bedsheet. A beach image comes last, and only on a strong laptop.
When the internet drops
A video call needs about 1.5 Mbps. The problem is never your average speed, it is the two minutes when someone at home starts a download.
Rejoining is always the same link. Apologise once, not three times: how calm you stay is the only thing being measured.
Meet, Zoom and Teams
Learn all three the night before. You do not get to choose which one the company uses, and "I couldn't get the app to work" is not a story you want to tell.
- Your display name is "Aarav Sharma". Not "aarav", not "Redmi Note 12", not your roll number.
- Stay muted while a panel talks among themselves; unmute before you begin, not halfway through your first sentence.
The coding round
You will be asked to share your screen and write code while they watch. Arrange the windows before you join, so you never drag things around while five people wait.
8 things that look unprofessional
Not one of these is about money or equipment. Every one is noticed in the first two minutes.
- Watching yourself in the corner of the screen.Your eyes flick sideways every ten seconds and everyone can see it. Hide self view after your last check.
- Interviewing from the bed, or leaning back on a pillow.Chair, table, feet flat, back straight. Your voice changes when you sit up.
- Eating, chewing gum, or drinking from a two-litre bottle.Water in a plain glass, sipped while they are talking, is the only thing that is fine.
- People or movement crossing the frame.Lock the door if you can. A door opening behind you takes the interviewer's attention completely.
- Loud typing while they speak.Keep a pen and one sheet of paper instead. Typing sounds like you are searching for the answer.
- Reading answers off a second window.Your eyes track left to right and it is obvious. Five keyword bullets on paper next to the lens, nothing more.
- Checking your phone, even once.Face down, out of reach, out of frame. Picking it up reads as "this call is not important".
- A crumpled t-shirt, a vest, or a busy pattern.Plain solid shirt, mid-tone blue is safest. Avoid pure white (the camera blows it out) and thin stripes or checks (they shimmer on video).
None of the eight costs money. A chair, a hidden self view, a phone in another room and one plain shirt kept ironed for interview days covers all of them.
