Practice the live format with an AI mock interviewer. Real-time voice, time pressure, follow-up questions, and an after-mock transcript that shows you exactly what happened. Available across coding, system design, and behavioral rounds — in 50+ spoken languages.
Solving 200 LeetCode problems in your text editor is not the same as solving 1 problem on a 45-minute live call with a stranger watching. The cognitive cost of being observed, talking through your reasoning out loud, and managing time pressure is its own skill — and you can’t build it without practicing the actual format.
Mock interviews used to mean scheduling a slot on Pramp or paying $200 per hour for Interviewing.io. PhantomCode lets you mock on demand, in your own language, at your own pace — and gives you a transcript afterward so you can study what actually happened.
Mock LeetCode in your text editor and you're not really practicing interviews — you're practicing problem-solving. PhantomCode mocks the live format with real-time voice, time pressure, and the same UX you'll have on the actual call.
Coding round (DSA + system design), behavioral round (LP-style stories), or mixed full-loop simulation. Toggle the format. The AI adjusts pacing and follow-up questions to match.
Read your own answers back. See where you rambled, where you under-explained, where you should have asked clarifying questions. The post-mortem you'd otherwise pay $300/hr for.
Pick L4, L5, L6, or staff-level. The mock interviewer scales question complexity, time pressure, and follow-up depth so your prep matches the bar you're actually targeting.
Most mock-interview tools assume English. PhantomCode handles 50+ spoken languages — including Hindi, Mandarin, Spanish, Portuguese, French, German, and Japanese — so you can rehearse the format before adding the language tax of English.
Python, JavaScript, TypeScript, Java, C++, C#, Go, Rust, Swift, Kotlin, Ruby. The mock interviewer matches idioms and standard library — including the gotchas that always come up in real rounds.
We’ve compared PhantomCode honestly against every major mock-interview platform — including the case for using PhantomCode alongside a peer-mock tool, not as a replacement.
