Ezra is a voice AI interviewer built by Ezra AI Labs, a San Francisco startup founded in 2024, and since May 2026 part of the hiring-software company Greenhouse, which sells it as Voice AI. An employer emails you a personal link, and you hold a two-way spoken conversation in which Ezra asks every candidate the same role-specific questions, follows up on your answers and answers your questions about the job. This page explains what Ezra is, what the interview is like, what it scores, the rules and practicalities, and how to prepare. We researched Ezra's own candidate pages and independent reports on November 12, 2026; employers configure these tools differently, so your invitation has the final word.
What Ezra is
Greenhouse announced a deal to buy Ezra AI Labs on May 5, 2026 and completed it on May 27, 2026; founder Ophir Samson became Greenhouse's head of Voice AI, and the old Ezra web addresses now point to Greenhouse's voice interviewing page. Ezra works inside Greenhouse and as a stand-alone product. HR Brew reported that it sits at the top of the funnel, often in place of the résumé screen: at Zapier it is part of the application itself, and at Blissway promising applicants book it at a time that suits them. Recruiters then receive a score, strengths and weaknesses, the interview length, a transcript and the recording. Greenhouse says Voice AI never rejects or advances a candidate by itself; people make every decision.
Who uses it: Zapier, Railsware and Blissway, in customer stories Greenhouse publishes. Railsware reports that 99 of 112 candidates completed it.
What the interview is like
| What to expect | |
|---|---|
| How you get it | A personal link from the recruiter, usually by email; you do not need to type an email address to begin |
| Format | A two-way voice conversation; you can interrupt it, and you can ask about the role, pay and benefits, which it answers only from content the employer approved |
| Questions | The same role-specific questions for every candidate, with follow-ups; the number is not published |
| Length | Set by the employer. Zapier's blog says 15 to 20 minutes; Greenhouse's Zapier story gives about 25 on average (31 for senior candidates, 22 for junior), and its Blissway story about 20 |
| Languages | 11, according to Greenhouse: English, Hindi, Spanish (Latin America and Spain), Brazilian Portuguese, German, French, Italian, Russian, Dutch and Japanese |
| Where | Available in the United States, with more regions planned, according to Greenhouse's May 27 announcement |
What it scores
- Each answer is scored from the transcript against the employer's questions, rubric and examples of strong, acceptable and weak answers, with a written reason; each question carries its own weight, and recruiters can override any score.
- Greenhouse says scores are not influenced by accent, tone, fluency, pace, personality or confidence, and that stutters and pauses are never scored.
- Flags for the recruiter: voice-based signals of outside help, each tied to a moment in the transcript; inconsistencies; overly scripted or AI-generated answers; and a résumé authenticity check.
- Warden AI audits Voice AI for bias every month, and the October 2026 audit on Greenhouse's trust page listed no concerns.
Rules and practicalities
- Greenhouse says candidates can opt out at any stage; Zapier says applicants who opt out get the same consideration. Greenhouse puts the opt-out rate at about 10%.
- Interviews are recorded and transcribed, and you see a recording and consent notice first.
- Outside help is exactly what the flags look for: a second voice, answers read aloud or AI-written replies are marked for the recruiter to review.
- Retakes, link expiry and device rules are not published. Zapier's blog mentions link resets and occasional response lag during its pilot, so if your link fails, ask the recruiter to reset it.
- If your application is deleted or anonymized, Greenhouse says the transcript, audio, scores and résumé data are removed permanently.
- Identity checks and accommodations are not described publicly; ask the recruiter for another format if you need one.
What candidates have reported
We found few independent first-hand accounts of Ezra, so most of what is public comes from employers' own pilots, and they are not neutral. Zapier reported a rating of 4.5 out of 5, 97% completion and about 5% of interviews flagged for integrity problems; candidates also told Zapier that Ezra could not answer company-specific questions. Railsware said 91% of candidates rated it excellent. Technical complaints in Zapier's pilot were link resets and occasional lag. Treat these figures as the employers' view rather than an average experience.
How to prepare
- Ask the recruiter how long your interview is and which language it runs in; both are set per role.
- Prepare a one-minute summary of your background and one example for each requirement in the job post, with a number or result. Scoring reads the transcript, so substance counts more than polish.
- Use a quiet room and headphones with a microphone; it is a spoken conversation, and another voice in the room can be flagged.
- Write down two questions about the role, pay or team. Ezra answers from employer-approved content; if it cannot answer, save the question for the recruiter, as Zapier's candidates had to.
- Speak in your own words rather than reading notes, since scripted delivery is one of the things Greenhouse says it flags.
Answering well when an AI is asking
- Find a quiet spot with a strong signal and avoid speakerphone, which causes echo.
- Answer every question fully; a skipped question usually scores as missing.
- Keep answers specific: what you did, when, and the result.
- Speak at a steady pace and avoid long silences, which some systems flag or treat as the end of an answer.

Your rights and what happens next
After a Ezra interview, a recruiter usually reviews the scores, transcript or recording, often within days, and decides whether to move you forward; most vendors say a human makes the decision. If you hear nothing in a week or two, a short, polite follow-up to the recruiter is reasonable.
Depending on where you live, the law may give you rights over automated interviews. Illinois requires employers to explain and get consent before using AI to analyze video interviews, New York City requires bias audits and advance notice for automated hiring tools, and the EU AI Act treats AI used in recruitment as high risk. You can ask the employer how your recording is stored and who reviews it, and request an alternative if you need an accommodation.
Where CoPilot Interview fits
AI-led interviews are screening rounds you take on your own, and they almost always forbid outside help; some log tab switches, pasted text or a second voice. So the useful preparation is practice. CoPilot Interview is an AI interview assistant; its free AI mock interview builds questions from your résumé and the job description, reads them aloud and scores each spoken answer out of ten, which is close to how many automated interviews work. The free plan gives 15 minutes a day of live help in sessions of up to 15 minutes, with AI mock interviews included. On the day, follow your employer's rules and the instructions in your invitation.
Disclosure: CoPilot Interview is our product, so weigh what we say about it accordingly.
