For engineers who think in another language

Your engineering is ready. Make your English interview prove it.

Rehearse the real interview out loud — by voice, against your real CV and a real job posting. The room talks back, follows up, and lets you interrupt it. So the day it counts, the English isn't what costs you the offer.

MockStage is a realistic AI voice-interview rehearsal tool for engineers who interview in a second language: you speak your answers out loud against your real CV and a real job posting, then get evidence-linked feedback pinned to the exact moments of your session.

Be first in line when early access opens. No spam, leave anytime.

  • Feedback pinned to the exact moment your answer slipped.
  • Won't cut you off mid-thought in a second language.

The accent tax

You can do the job. The interview is what costs you the offer.

You ship the system. You debug under load. But the offer hangs on thirty minutes of speaking a second language under pressure — and that has nothing to do with your engineering.

It's the pause that reads as hesitation. The follow-up that lands before you've found the word. Rehearsal is how you stop paying the accent tax.

How it works

Rehearse the pressure, not just the questions.

Generic mock questions don't sound like your interview. MockStage builds the room around the exact role you're chasing — then makes you speak.

Your CV. Their job post.

Paste a job URL and we build a dossier from the real posting. Add your real CV. The questions come from that overlap — not a generic bank.

Four interviewers, four pressures.

Stack the rounds the way a real loop does. Each persona pushes on a different nerve — the warm-up, the deep technical, the trade-off call, the why-you.

It follows up. You answer back.

Voice rehearsal that talks like a person: it digs into your answer, throws the curveball follow-up, and lets you cut in and recover as you speak.

Voice rehearsal opens to early access first — join the waitlist to get in.

I'm a Brazilian engineer. Day to day, my English was never the problem — but the pressure of an interview made me freeze, and I lost offers I was qualified for. MockStage is the rehearsal I wish I'd had.

Frequently asked

What is MockStage and how does it work?

MockStage is a voice-first rehearsal room for the interview you're actually walking into. You paste your real CV and the URL of a real job posting — we scrape that posting into a dossier — and the questions come from where the two overlap, not a generic bank. You pick the interviewers you want to face: HR, Technical, Manager, Executive. Then you run a live session out loud. The interviewer listens, follows up on what you actually said, and lets you interrupt and recover the way a real person would. Afterward you get feedback linked to evidence across four dimensions — content, communication and delivery, structure, and pressure response — each note pinned to the exact moment in your own session, plus a score you can track as you practice. The whole point is to rehearse the pressure by voice, not to click through a quiz.

When can I use it? Is it available now?

Not yet — MockStage is in pre-launch, and this site is the waitlist. Early access hasn't opened, so there's nothing to log into today. What you can do now is join the list: drop your email, and if you like, set up the interview you're worried about so your session is ready to run the moment your spot opens. We don't have a public launch date to promise, and we'd rather not invent one. Voice rehearsal opens to early access first, and people on the waitlist go in ahead of everyone else — so the honest answer is that joining now is how you get in soonest and how you'll hear the instant it's live. We'll send one email when your spot is ready. No spam in between, and you can leave the list at any time.

How much does it cost? Is it free?

Pricing isn't announced yet, so we're not going to quote a number we might have to walk back. MockStage is still in pre-launch, and we'd rather set the price once — honestly — than promise something today and change it later. That also means we're not claiming it's free or that there's a free tier; we simply haven't finalized how it works. What we can tell you is what you're joining: a waitlist, at no cost and no commitment, that puts you first in line when early access opens. When pricing is ready, people on the list will hear it directly and clearly, before it goes public — no fine print, no surprise charge for joining. If cost is the deciding factor for you, the best move is to join the waitlist and wait for that email rather than guess.

Who is it for? Do I need to be at a certain level?

MockStage is built for one person in particular: the engineer who can clearly do the job but has to prove it in a second language, under time pressure, out loud. If English is where the interview costs you — the pause that reads as hesitation, the follow-up that lands before you've found the word — that's exactly the gap we're aiming at. Level isn't a gate. Whether you're interviewing for your first US role or you're a senior who's shipped for years, the pressure of speaking under interruption is the same muscle, and that's what you rehearse here. You configure the role, level, and interview style you're actually targeting, so the room matches your situation rather than some generic average. You don't need to be 'ready' to start rehearsing — rehearsing is how you get ready. If you interview in a language that isn't your first, this is for you.

How is it different from other AI mock-interview tools?

Most mock-interview tools are typing tools: you read a question, type an answer, get a rubric back. That's not where second-language interviews break. They break out loud — in pacing, in the pause before the right word, in what happens to your clarity the moment someone interrupts. MockStage is voice-first on purpose. You speak, the interviewer follows up on your actual words, and you can cut in and recover mid-sentence, because that's the real thing. It's also built narrow instead of broad: the questions come from your real CV crossed with a real job posting, not a generic bank, and the personas stack the way an actual interview loop does. And the feedback points somewhere — every note is pinned to a real moment in your session across four dimensions, so you get 'here's where it slipped and why,' not a vague 'be more confident.' Narrow, spoken, and evidence-linked is the difference.
