Practice that tells you something useful
Reading a list of “top 50 questions” isn’t practice. Answering one under pressure, fumbling it, and finding out exactly why — that is.
It listens, then digs deeper
One question at a time, and the next one follows from what you just said. Stuck? You get a nudge, never the answer.
Try a round →You’ll know where you stand
Scored on the five things real interviewers weigh — then watch your average climb, session after session.
See how scoring works →Nobody’s watching
Your transcripts and scores stay yours. Nothing is recorded, and you can delete any session for good.
How we keep it private →How a session works
Three steps, about fifteen minutes
Pick your round
Frontend, Backend, Full-stack, DSA, System design — or a mixed round with behavioural questions. Three questions or eight; you decide how long you have.
Answer it out loud
Type it or say it. Every follow-up comes from the answer you just gave, and a nudge arrives if you stall. Skip anything and come back to it.
See where you landed
A score, what you handled well, and what to work on next. The full transcript is yours to reread — or delete.
Walk away with something to show for it
Finish a scored session and your Certificate of Completion is ready to download — your name, your track, your score, signed by whoever ran the interview.
- A real grade. A+ Outstanding down to C Satisfactory, not a bare number.
- Its own reference. Every certificate is numbered.
- A QR code. Anyone can scan it and see the certificate is genuine.

Two ways to practise
Pick the one you need today
Sit across from a
real person
Forty minutes with a working engineer. They ask, you answer, and afterwards you get their written read on how you did.
Rehearse on
your own time
No scheduling, nobody watching. Run the same topic at midnight until it stops catching you out.
Pay per session, no subscription
Nothing recurring and no surprise charges. Buy a session when you want one — you'll see the final amount, including GST, before you pay.

Better to fumble an answer here.
A ten-minute round is three questions. That's usually enough to find the one you can't explain yet.
