For devs interviewing in English

Practise the interview
before it counts.

You know the system design. Then the call starts in English and the words come out wrong.

Byte is an AI interviewer you can talk to out loud, as many times as you like. It fixes your English and sharpens your answer.

Byte: Ready when you are. Tell me about a project you're proud of.

What a round actually looks like

You talk. Byte listens, answers, and pushes back. Then you get both kinds of notes — most tools only give you one.

Good instinct. Now name the eviction policy and say what happens on a cache miss — that's the follow-up they'll ask.

Questions people ask

No. It runs in your browser. Voice works best in Chrome or Edge — anywhere else you can type your answers instead and Byte still talks back.

We never receive your audio. Your browser turns speech into text on its own, and only that text reaches the coach. We don't keep your conversations either — just which round you practised, how long, and how many corrections you got.

That's the point. Byte is patient, never sighs, and doesn't tell your boss. Fumbling here is free; fumbling in the real call isn't.

A short practice session every day, forever, without a card. A pass removes the limit when you've got an interview coming up.

Yes, though a laptop with a decent mic makes for a more realistic round.

No. Passes are one-time payments that expire on their own. Nothing recurring, nothing to cancel.

The next interview is happening anyway.

Better to fumble the answer here, at 11pm, talking to a robot who has all the patience in the world.
