What happens in the first 90 secondsThe first 90 seconds

You talk. Dana pushes back. You see the number.

0:00

She asks a real question

Not "tell me about yourself". A question built from the job you pasted — the kind the hiring manager at that company actually asks.

0:35

She interrupts when you ramble

"Stop — what was your decision? Start with that." Uncomfortable on purpose. Real interviewers think it; Dana says it.

1:30

You see your scorecard

Clarity, concision, structure, confidence, vocabulary — and the one sentence that names your biggest problem. Then the offer.

Why it works when a video course doesn'tWhy it works

Three things no interview course does

It's out loud, and it talks back.

Reading tips changes nothing. Saying the answer, getting cut off, and saying it again in 45 seconds changes the answer.

It knows the company.

Name the company and position. Dana reads up — recent news, products, how their interviews run — and asks about that.

It counts down to your date.

Ten minutes a day, harder each day, full mock interviews on days 7, 14 and 20, and a calm interview eve. Built around your date, not "someday".

Your biggest problem

You take 25 seconds to reach the reason. Open with it: "Because you're the only company on my list where QA owns the release decision." Then the evidence.

Avi ShulkinFounder · Israel

"I rehearsed out loud, alone, before every conversation that mattered — in my second language. Nobody sells that rehearsal; they sell tips. So I built the rehearsal."

One founder, no investorsReplies personally to support
Who built this, and who it's for

Made for the interview in your second language. Works for your first.

Engineers in Bangalore, analysts in São Paulo, product managers in Tel Aviv — interviewing at global companies in English. And native speakers who go blank the moment it matters. The fear is the same; the fix is the same: say it out loud, get pushed, say it again.

Privacy & the line we don't cross

Your recordings are yours. And this is practice.

Recordings are stored for your sprint so you can hear yourself improve, deleted 30 days after your interview date, never used to train models, never shared. Question Proof never joins, listens to, or assists a real interview — there is no "copilot" and never will be. We'd rather you actually be good.

Questions people ask before payingBefore you pay
Is this cheating?
No — and we've drawn a hard line. Question Proof is practice before the interview. We never join a live interview, never feed you answers during one, and there is no 'stealth mode'. Tools that do that are treated as fraud by employers; we think you should walk in ready instead.
What happens to my recordings?
They're yours. We keep them so you can hear your day-1 answer next to your day-19 answer, then delete them 30 days after your interview date. We never use them to train models and never share them.
I'm not a native English speaker — does it work for me?
It was built for you first. Dana understands accents, and scoring measures clarity and structure — never accent. Everything is in English; other interface languages come later.
Which roles and companies does it cover?
Any role you can paste a job description for. Dana researches the company you name — recent news, products, how they interview — and builds the questions from your job description, not a generic bank.
How long does a session take?
About ten minutes a day. Full mock interviews on days 7, 14 and 20 take 20–30 minutes. The free trial is 90 seconds.
