How to build an AI recruiter that gives every applicant a fair shot

Most hiring funnels quietly filter out great people before a human ever meets them.

Applicants get stuck behind forms and keyword screens. Recruiters get buried in résumés. Candidates never get to speak, with only 2% of candidates ever getting an interview.

You can flip that script with an AI recruiter built on Tavus—a lifelike, face‑to‑face interviewer that meets every applicant, captures richer signals than a form ever could, and drops a structured report back into your ATS. It looks people in the eye, listens, reads context, and follows a consistent interview rubric at scale.

Below is a practical, step‑by‑step guide to ship this in days—not months—plus the why behind each choice.

Why an AI recruiter on Tavus beats forms, chat, and “talking heads”

Everyone gets a fair shot.‍

A standardized first‑round screen means every candidate can speak, not just the ones who nailed the keyword sort. Tavus’ AI Recruiters & HR use case explicitly targets bias reduction with consistent, rubric‑driven experiences that don’t vary by mood or calendar load.

It feels human, so people actually engage. Tavus isn’t a lip‑sync avatar. Three purpose‑built models work together to create presence:

• Phoenix‑3 renders full‑face micro‑expressions and perfect lip‑sync, closing the “uncanny” gap that makes most avatars brittle.
• Sparrow‑0 handles natural, interruption‑friendly turn‑taking with sub‑600ms response timing, so conversations feel like conversations.
• Raven‑0 adds real‑time perception: it sees the candidate and setting, notices gestures, and can trigger automations based on what it observes. That’s a new data layer you simply don’t get from audio‑only or text.

If you’ve wondered whether visual, humanlike interviews change behavior, partners have already seen the effect. In mock‑interview scenarios, users stayed 42% longer and completed 35% more sessions when the interviewer felt real and responsive—because presence builds commitment.

It comes back structured. Tavus can follow Objectives & Guardrails, collect the answers you need, and output a clean scorecard—no meandering, no improvisation. Then it can function‑call your ATS to post notes, submit ratings, or move the candidate to the next stage.

It’s ready for enterprise. 1080p video, 30+ languages, conversation transcripts/recordings, and SOC 2/HIPAA options (plan‑dependent) make it deployable in real pipelines, not just experiments.

And beyond features, the brand promise matters: Tavus’ mission is to teach machines to be human—to replace clunky interfaces with presence and empathy. That’s the point of an AI recruiter: a machine that listens like a person, at scale.  

Two ways to build it: No‑code studio vs. API

You can ship your AI recruiter two ways:

1. AI Human Studio (no‑code). Fastest route. Design the recruiter visually, load your knowledge, set up objectives (your rubric), connect to ATS via webhooks or native actions, and go live in days. Ideal if you want speed, branding, and minimal engineering lift.
2. CVI API (Conversational Video Interface). Full control for product teams. Embed a face‑to‑face interviewer inside your app, wire in your own LLM or tools, and own the UX end‑to‑end. Best if you’re integrating with a custom candidate portal or want deep ATS logic.

Either path uses the same human simulation backbone—Phoenix‑3, Sparrow‑0, Raven‑0—so the “feel” is the same. Choose based on your integration appetite and timeline.

The build:

1) Define your recruiter’s purpose, persona, and disclosure

In Persona Builder, give your AI recruiter a short, candid brief:

• Role: “You’re a first‑round technical recruiter.”
• Goal: “Screen for must‑have skills, motivations, logistics, and culture adds.”
• Disclosure: “You are an AI interviewer from [Company].” (Always disclose.)
• Greeting: “Hey—thanks for applying. I’ll ask a few questions and share next steps.”

Persona Builder generates starter objectives and guardrails; you can also author them yourself. Keep it short; presence over process.  

2) Load your knowledge base (Fast RAG)

Upload JDs, leveling guides, compensation bands, benefits, interview rubrics, and a “company story” doc. In CVI, assign these docs to the persona so answers are consistent and grounded. Tavus’ Knowledge Base uses ultra‑fast retrieval (responses in ~30 ms) so the candidate never feels latency drift while the recruiter references policy or role‑specific content.

API sketch (document upload):‍

curl -X POST https://tavusapi.com/v2/documents \
  -H "Content-Type: application/json" \
  -d '{
    "document_url": "https://files.company.com/recruiting/rubric.pdf",
    "document_name": "Eng L3 Screen Rubric",
    "document_retrieval_strategy": "balanced",
    "tags": ["recruiting","rubric"]
  }'

Assign the returned document_id to your conversation/persona.

3) Define Objectives & Guardrails (your structured rubric)

Structured screens beat vibe checks. Add JSON‑like Objectives:

• collect baseline logistics (work auth, timezone, salary range)
• validate must‑have skills with 2–3 probes
• assess communication clarity and role motivations
• score on a 1–5 scale across competency buckets
• output a short, neutral summary and recommendation

Layer Guardrails to keep it compliant and on‑brand (e.g., no protected‑class questions; always disclose AI status; give time to ask questions).

4) Choose the “face”: stock or custom replica

You can start with a stock replica (100+ options) or train a custom recruiter in minutes (≈1 minute of source video is enough to capture identity and nuances). For enterprise rollouts, opt into professionally optimized replicas.

5) Configure reporting, transcripts, and recordings

Your conversations will automatically generate transcripts, and—in Growth plans and up—recordings for auditing and coach‑back. Set a report schema (example below). Reports can blend conversational data with Raven‑0’s perception cues (talk‑time ratio, interruption count, confidence signals) for a fuller picture—now you’ve upgraded from “checkboxes” to high‑signal, low‑bias evidence.

6) Push it to your ATS automatically

Use function calling from the conversation to hit your ATS (e.g., Greenhouse, Lever, Workday custom endpoints) or subscribe to a callback_url that receives the conversation summary when the objective is complete. Store the report as an application note, update stage, and attach a link to the recording/transcript.

api sketch (create conversation and webhook it):

curl -X POST https://tavusapi.com/v2/conversations \
  -H "Content-Type: application/json" \
  -H "x-api-key: $TAVUS_API_KEY" \
  -d '{
    "replica_id": "recruiter_replica_01",
    "conversation_name": "eng-l3-screen",
    "callback_url": "https://ats.company.com/webhooks/tavus",
    "document_ids": ["doc_rubric_001","doc_benefits_002"],
    "properties": {"enable_recording": true, "max_call_duration": 900},
    "memory_stores": ["candidate_{{ATS_ID}}"],
    "conversational_context": "You are a first-round recruiter for Engineering L3..."
  }'

When the conversation ends (or a key event fires), your webhook gets the payload.

7) Pick the right plan, then scale

• Start free to prototype; move to Starter for perception and turn‑taking; Growth adds recordings, white‑labeled consent, and professionally optimized replicas; Enterprise brings custom concurrency and compliance. Concurrency limits (1/3/15/custom) and minute bundles let you right‑size for demand.
• SOC 2/HIPAA compliance is available at higher tiers if your pipeline touches PHI or requires strict controls.

Interview flow that actually works (copy/paste)

Opening (30s)

• disclosure + purpose
• set expectations: “10–12 minutes, then a quick summary.”

Baseline checks (2–3 min)

• eligibility, work auth, location, comp window, timing

Skills probes (5–6 min)

• 2 targeted questions from the JD; ask for a concrete example
• 1 behavioral probe (“tell me about a time…”) matched to your values

Candidate questions (1–2 min)

• Tavus answers directly from your Knowledge Base so every candidate hears the same story about role, team, benefits, and process (with 30ms retrieval, it’s instant).

Close (30s)

• confirm next step, share timeline, thank them

Guardrails keep it consistent; Objectives ensure the scorecard is fully populated before ending.

Quality, fairness, and privacy (what to check before launch)

• Bias controls. Keep questions tied to competencies; use neutral summaries; audit early transcripts/recordings for drift. (Recordings are available from Growth; transcripts across tiers.)
• Consent and disclosure. Use white‑labeled consent and make AI status explicit at the start. (White‑labeled consent available on Growth/Enterprise.)
• Data governance. Store transcripts/recordings per your policy; restrict who can access; leverage SOC 2/HIPAA options where required.
• Tone. Your recruiter should sound like your brand—direct, empathetic, human. Tavus’ voice guidelines emphasize presence over process; skip the jargon and get to the point.

Performance and cost tips

• Start with stock; graduate to custom. Stock replicas get you live; custom replicas (one minute of source video) deliver perfect brand fit later.
• Training overage. Budget for replica training overage ($40–$65 per replica, tier‑dependent) if you scale personas.
• Minutes + concurrency. Size your plan to your weekly applicant volume and preferred SLA. Max concurrent streams (1/3/15/custom) is the lever for peak hours.
• Languages. Run the same screen in 30+ languages to widen your funnel without opening duplicate reqs per locale.

Copy‑ready checklist

• Persona (purpose + disclosure) in Persona Builder
• Objectives & guardrails (logistics, skills, motivation, summary)
• Knowledge Base: JD, leveling, comp, benefits, company story (fast RAG)
• Replica selected (stock now; custom later)
• Transcripts/recordings enabled (plan‑based)
• Report schema finalized + ATS mapping
• Webhook/function call wired to ATS
• QA for fairness, tone, and brand voice (presence over process)

The bottom line

An AI recruiter on Tavus isn’t a gimmick. It’s a humanlike front door to your hiring funnel that lets every applicant be heard, returns structured, auditable signal, and plugs cleanly into your ATS. It’s how you scale empathy without sacrificing rigor—the emotional intelligence of humans, with the reach and reliability of machines.

When the frontier arrives, meet it face‑to‑face.
