Why We Built an AI Interviewer Avatar (and Why It Matters)
When we started building Humanly’s AI Interviewer, we weren’t trying to make something flashy.
We were trying to solve a very real problem in hiring:
Candidates give better answers when the interaction feels human.
That insight shaped one of the most intentional decisions we made. Building a realistic video avatar, rather than relying purely on voice-only automation or text-based bots.
This is the story of why we did that, how we did it, and what it changes for hiring teams.
The Hidden Cost of Low-Quality Interactions
Recruiting teams are under pressure to move faster and interview more candidates, but speed often comes at the expense of interaction quality.
Most automation tools today rely on:
- Voice-only phone screens
- Text-based chatbots
- Asynchronous video prompts
These approaches are efficient, but they often produce shorter, lower-context responses. Candidates rush. They guess. They disengage.
And that creates a downstream problem:
Hiring decisions get made on thinner information.
A Simple Metric That Changed Our Thinking: Words Per Response
As we evaluated different interview formats, one metric stood out as a powerful proxy for interaction quality:
How much candidates actually say.
More words don’t automatically mean better answers, but consistently, richer responses correlate with better context, clearer intent, and stronger signal for hiring teams.
Here’s what we found when comparing industry benchmarks to Humanly’s AI Video Interviewer:
| Interview Type | Average Words per Response |
|---|---|
| Humanly AI Interviewer | 201 |
| Human – Zoom (industry) | 150–250 |
| Human – Phone (industry) | 120–200 |
| Async Video (industry) | 100–200 |
| Automated Phone | 75–150 |
| Chatbot | 20–50 |
| SMS | 10–30 |
👉 Key takeaway:
Video-based, face-to-face interaction, even with AI, drives dramatically more detailed responses than voice or text alone.
This isn’t about novelty. It’s about presence.
Why Video (and Why an Avatar)
So why not just use voice?
Because humans are wired to respond differently when they see a face.
Video:
- Encourages longer, more thoughtful answers
- Reduces awkward pauses and confusion
- Helps candidates feel “heard,” even in automated settings
- Provides better non-verbal and contextual cues
But not all video experiences are created equal.
Early on, we realized that generic avatars or uncanny animations actually reduced trust. They distracted candidates instead of engaging them.
So we made a deliberate choice:
Build a custom, realistic avatar that feels natural, not robotic.
The Making of the Humanly Avatar
To get this right, we didn’t start with software; we started with a human.
We partnered with a professional actor and filmed them on a green screen, capturing natural facial expressions, pacing, tone, and body language. Every detail mattered:
- How questions are delivered
- How pauses feel
- How attention and empathy are conveyed
Our goal wasn’t to “trick” candidates into thinking this was a human interviewer. Transparency matters.
The goal was simpler—and harder:
Make the interaction feel comfortable enough that candidates forget about the technology and focus on answering the question.
Better Answers Lead to Better Hiring
When candidates give longer, more thoughtful responses:
- Recruiters get clearer signals earlier
- Screening decisions are more consistent
- Bias introduced by rushed or incomplete answers is reduced
- Hiring velocity improves without sacrificing quality
This is especially critical for:
- High-volume hiring
- Hourly and frontline roles
- Early-stage screening where every drop-off matters
Automation shouldn’t strip away humanity.
It should create more room for it.
AI Interviews Create More Value for Candidates, Too
It’s easy to talk about AI interviews in terms of efficiency for hiring teams. But one of the most important outcomes we’ve seen is how much better the experience becomes for candidates.
At its core, interviewing is about being understood. And too often, traditional screening methods fail at exactly that.
Every Candidate Gets Into the Conversation
Resumes are blunt instruments. If you don’t have the right keywords, the right job titles, or the “right” background on paper, you may never get the chance to explain yourself—no matter how capable you are.
AI interviews change that dynamic.
By automatically inviting every applicant into a structured conversation, AI Interviewers ensure that:
- Candidates are evaluated on what they say, not just what’s on their resume
- Transferable skills and non-linear career paths actually show up
- Strong potential isn’t filtered out before it’s ever heard
For many candidates, this is the first time the hiring process feels like it’s actually giving them a voice.
Helping Hiring Teams Know Candidates Better
Richer responses don’t just benefit recruiters—they benefit candidates, too.
When candidates can fully explain their experience, motivation, and context, hiring teams get a more complete picture of who they are beyond credentials. That leads to:
- Fewer mismatches later in the process
- More relevant follow-up interviews
- Better alignment between role expectations and reality
The result is a hiring conversation that feels more mutual and less transactional.
Candidates Engage More—and Ask More Questions
One of the most telling signals we’ve seen is how candidates behave during AI interviews.
When interviewing with Humanly’s AI Interviewer, candidates ask 1.2 more questions on average about the role and the company compared to human-led interviews.
That matters.
More questions signal:
- Higher engagement
- Greater clarity about the role
- Increased confidence in the process
Candidates aren’t just answering prompts—they’re actively participating in a two-way conversation.
Support Beyond the Interview: AI Career Coaching
Interviews shouldn’t be a one-off moment of pressure. They should be part of a broader journey toward the right role.
That’s why Humanly also offers an AI Career Coach designed to support candidates before and beyond the interview itself. The AI Career Coach helps candidates:
- Discover roles that align with their skills and interests
- Understand what hiring teams are looking for
- Practice with mock interviews to build confidence and clarity
Instead of guessing how to prepare—or whether they’re even applying to the right job—candidates get guidance that helps them show up as their best selves.
A More Human Experience, Powered by AI
When designed thoughtfully, AI doesn’t distance candidates from the hiring process.
It does the opposite.
By giving every applicant a chance to be heard, encouraging deeper engagement, and helping candidates prepare and find the right opportunities, AI interviews can make hiring feel more human—not less.
And that’s when everyone wins.
Designing for the Future of Hiring
The future of recruiting isn’t just faster funnels or more automation.
It’s higher-quality conversations at scale.
That’s why we invested in:
- Video-first AI interviewing
- Realistic, human-centered avatar design
- Measuring interaction quality, not just completion rates
Because in hiring, how you ask matters just as much as what you ask.
And when candidates feel engaged, respected, and comfortable, you get better answers. Every time.
