OpenAIPractice that feels like the real thing.
Other tools whisper answers during the real call. We help you rehearse until you don't need them.
Realism
The actual interview, simulated. 19 personas, ~400ms voice reply, live coding, and video replay.
Honesty
Get better, not sneakier. Screen-share safe, with zero real-time interference — a practice tool that never runs during a real interview and never feeds you answers.
Reach
True global support. Practise seamlessly in 47 languages, leaving English-only limitations behind.
Full mocks for every major English test.
IELTS, TOEFL, PTE and Duolingo — timed, scored, and built to feel like the room you will sit in. Plus live roleplay for the conversations you only get one shot at.
Lowest dead air
Two seconds of silence feels broken in a live interview. Mid-turn replies start in ~400ms — measured end-to-end on our conversational voice engine.
Pipelined voice
First sentence synthesises and plays immediately; the rest builds during playback. No waiting for the whole reply to render.
Streamed first sentence
The live model streams while you speak; TTS starts on the first complete sentence so reply audio is ready when your turn ends.
Pause-aware turn-taking
Knows a breath from a finished answer. The interviewer waits when you are mid-thought — and answers when you are done.
Everything the real room throws at you.
Speak your answers out loud — hands-free.
No buttons, no typing. Voice-activity detection knows when you start and stop, pause-aware turn-taking waits out a breath, and the next question lands at conversation speed (~400ms mid-turn).
A scored report the moment you finish.
A scorecard tuned to your interviewer's rubric, a full transcript, and answer-by-answer coaching on precisely what to say better next time — never generic tips.
“Tell me about a time a design decision came back to bite you.”
Strong ownership, but you described the fix before the impact. Lead with what broke and who it affected.
Say instead: “We shipped a schema that couldn't handle multi-region writes — it cost us six hours of downtime, and I owned the migration.”
Replay any answer on video.
Interview sessions are recorded unless you switch recording off. In the report, hit Watch on any answer to see exactly how you delivered it — the fastest way to fix filler words, pace, and presence.
Lowest dead air
~400ms voice reply. Semantic turn-taking, speculative replies, and pipelined TTS — not a robot thinking out loud.
Live coding rounds
A built-in editor for SWE & DS rounds — write and run code the interviewer sees.
Practise in 47 languages
Run the whole interview — questions, voice, and feedback — in your language.
Interviewers with range
From a warm hiring manager to a relentless FAANG director — each with its own voice and rubric.
19 interviewers. You only ever meet the right one.
You don't browse a roster and hope. Tell us the role and the round, and we bring the interviewer who runs it — with their own voice, temperament, and scoring rubric.

People who practised, then got the offer.
“I froze on system design in my last two loops. Three weeks with Kai and I walked into Amazon actually calm — got the offer.”
“The follow-up questions are what got me. It caught every vague answer exactly like a real PM interviewer would. Nothing else does this.”
“English isn't my first language and interviews terrified me. Practicing out loud here every night rebuilt my confidence completely.”
“Watching my own replay was brutal in the best way. I had no idea how many times I said 'um'. Fixed it in a week.”
“Cheaper than one hour with a human coach and I did twelve full mocks. The scorecard told me exactly what to fix each time.”
“Hit IELTS band 8 on the first try. The examiner mode felt identical to the real test and the band feedback was spot on.”
“The live coding round is the real deal — I wrote code, it watched, it dug into my complexity choices. Exactly like my Google onsite.”
“Did my consulting case prep at 6am before work, out loud, every day. Landed BCG. I genuinely couldn't have without this.”
“I'm a career switcher and had zero interview reps. This gave me forty before my first real one. Night and day difference.”
“The gap after I finish talking is tiny — it actually feels like a conversation. Every other AI mock felt like leaving a voicemail.”
