Interview Signal vs Carv: an agentic hiring platform or a desktop interview tool?

Carv describes itself as an autonomous hiring platform for volume hiring: AI agents that screen, schedule and onboard candidates, plus an assistant that captures candidate interactions on video, phone, chat or in person and writes structured data into ATS platforms including Bullhorn, JobAdder and Loxo, with prices available only on request as of October 2026. Interview Signal is a desktop app for the person running the interview: no bot joins the call, a question guide runs from the job description, and the output is a scorecard with the candidate's quotes and a client submittal, with published prices and no ATS integration. Choose Carv if you want ATS write-back and automation across a high-volume funnel; choose Interview Signal if one recruiter wants a better interview and a better write-up without buying a platform.

We make Interview Signal. Every fact about Carv below comes from Carv's own site, checked in October 2026 and linked. Carv's site has shifted its emphasis: the address of its interview product page now redirects to a blog guide, and its homepage leads with agents.

How do Interview Signal and Carv compare at a glance?

Carv cells link to their source. "Not published" means we did not find it on Carv's own pages; ask Carv directly.

Does Carv join the call as a bot?

Carv does not say so in plain terms on the pages we checked. Its Bullhorn integration page says Carv "joins every candidate interaction, takes notes, and turns them into ATS-ready structured data", and that it "supports every format: video, phone call, text chat, or in-person meeting." A post on Carv's blog says the assistant joins "face-to-face meetings, phone calls, and virtual meetings," supports Google Meet, Microsoft Teams and Zoom, detects upcoming meetings from Google Calendar or Outlook, and accepts uploaded recordings from other tools. Ask Carv during a demo what a candidate sees in a video call.

Interview Signal never joins the call. It runs on Windows 10/11 or macOS 13 or newer, labels the microphone as the interviewer and the meeting's sound as the candidate, and works beside Zoom, Teams, Google Meet and phone screens that run through the computer. It cannot capture a chat conversation, a meeting you are not in, or an in-person interview on a phone, because there is no mobile app.

Which one handles phone screens?

Both, in different ways. Carv's integrations page lists Aircall under telephony and Zoom, Teams and Google Meet for meetings, and the Bullhorn page names phone calls among the formats it supports. For a desk that dials through Aircall, that is a direct route.

Interview Signal captures a phone screen whenever the call runs through the computer's audio, such as a softphone, with no dialer integration. See our guide to recording a phone screen for setups that work.

What lands in your hands after the interview?

Carv's output is aimed at the ATS. The Bullhorn page says Carv "prefills your ATS after every interaction with structured data in the right fields," which you can review and edit before saving, and that it produces structured outputs for "candidate write-ups and reports." Carv's blog post goes further: meetings marked as interviews generate candidate profiles and presentations, intake calls produce job descriptions, and output templates can be adjusted to a client's tone and branding. That is close to what Interview Signal calls a client submittal, and Carv sends it into the ATS rather than leaving it on your desktop.

Interview Signal's strength is during the call and in the evidence. It builds a question guide from the job description, pins must-ask questions until you ask them, suggests follow-ups with a reason (probe, clarify or evidence), fills the scorecard as the interview goes and scores on demand with Evaluate, with an optional second model (Dual AI). A private answer check flags answers that read as AI-written or read aloud, suggests a question to try, and never changes a score or reaches the submittal. Afterward, each score carries the candidate's own quotes, checked against the transcript, and the submittal follows your agency's template. We did not find an in-call question guide or a quote check described on Carv's pages.

Which one writes into your ATS?

Carv, clearly. Its integrations page lists Bullhorn, JobAdder, Loxo, Greenhouse, Lever, Workable, Recruitee, Recruit CRM, Avionté, Avature, Carerix, OTYS, RecruitNow, Ezekia, Jobylon and Tigris. For an agency on one of those systems whose main pain is retyping notes, this is the most important row on the page.

Interview Signal has no ATS integration. It exports by copy, Markdown, Word, a CSV row, email or Slack, and shapes notes for Bullhorn, Greenhouse, Lever or JobAdder so the paste lands in the right place, but a person still does the pasting. Our guide to note-takers for Bullhorn compares the tools that do write back.

Where does the interview data go?

Carv says it keeps "your existing systems as the source of record" (how it works), which means interview data flows into your ATS. We did not find a storage location or retention period on the Carv pages we checked; ask for its security documentation.

Interview Signal keeps transcripts, quotes, candidate names, notes and submittals on the recruiter's computer. Audio goes to a speech-to-text provider in short chunks during the call and is not retained, and our server keeps only counts and durations (security details).

How much does each one cost?

Carv's pricing page shows no prices as of October 2026, only "Request a demo." An undated Carv blog post says "Carv is available for free for the first 5 meetings" and that "The Recruiter Pro plan starts at $60 per user/month and offers unlimited meetings," with a custom plan for agencies; treat those figures as unconfirmed until Carv quotes you.

If you need a number for a budget today, Interview Signal can give you one and Carv cannot. If you need ATS write-back and screening agents, a quote from Carv is the only way to compare.

Should you choose Carv or Interview Signal?

Choose Carv if:

• Your agency runs on one of its 16 listed ATS platforms and you want notes and data written in automatically.
• You hire at volume and want chat or voice agents to screen and schedule candidates.
• You need capture across phone, chat and in-person interactions, not only computer calls.
• You are buying a platform for a team, through a sales process.

Choose Interview Signal if:

• You want no bot in the call and a question guide in front of you while you interview.
• You want each score backed by quotes checked against the transcript.
• You want published prices and can start with 20 free minutes.
• You accept the gaps: no ATS integration, desktop only, no video, and a newer product with few public reviews.

Best for, in one line: Carv is best for staffing and volume-hiring teams that want ATS automation and screening agents; Interview Signal is best for recruiters who want a structured interview and a client-ready write-up from their own desktop.

What should you ask before you decide?

1. Carv: what does a candidate see when the assistant joins a
   Zoom or Teams interview? Is there a participant?
2. Carv: what does the current plan cost per user, and is the
   blog's Recruiter Pro figure still valid?
3. Show one interview written into our ATS by Carv, and the same
   interview pasted in from Interview Signal. Compare the time.
4. Where is interview data stored, and for how long?
5. Run one real phone screen through each.
