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.

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.
byte › How would you keep the feed fast as it grows?
you › I think we can to use a cache for the most readed posts…
Your English
can to use→could use
readed→read
Your answer
Good instinct. Now name the eviction policy and say what happens on a cache miss — that's the follow-up they'll ask.
Every round, not just the easy one
Most practice stops at “tell me about yourself”. The rounds that cost people offers are further down.
Behavioral
“Tell me about a time you…”
System design
“How would you scale this?”
Coding out loud
“Walk me through your approach.”
CTO chat
“Why are you leaving your job?”
Salary talk
“What are you expecting?”
Three steps, about ten minutes

Talk out loud
Byte asks. You answer with your voice. No script.

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.
