HeyMilo vs Tenzo

Which Voice AI is Built for Real Hiring Scale?

June 3, 2025

Voice AI is transforming how recruiters engage with talent — and both Tenzo and HeyMilo are leading players in that shift. Each platform offers conversational voice interviews, multilingual capabilities, and ATS integrations designed to eliminate early-stage busywork.

But beneath the surface, Tenzo is built for recruiters who need more than just automated calls. It’s the platform for teams that want speed and intelligence — consistency and control. If HeyMilo helps you screen faster, Tenzo helps you screen smarter, scale better, and close stronger.

🧠 Smarter Interviewing Starts at the Resume

At a glance, Tenzo and HeyMilo may look similar — both use friendly voice agents to screen candidates 24/7. But the intelligence behind those interviews is where the gap begins to show.

This makes Tenzo far more effective for teams hiring across varied roles, industries, or seniority levels. The conversation feels personalized — not robotic. And you get signal that’s relevant to your criteria, not just generic responses.

📐 Precision Built into Every Step

Creating interviews in Tenzo is fast and intuitive. Recruiters configure each question side-by-side with its scoring logic — no switching between screens, no guessing how things connect.

HeyMilo splits these workflows. That creates more friction and slows teams down, especially when managing dozens of roles or rotating users in and out of the platform.

Just as importantly, Tenzo offers deterministic scoring:

Same input = same score, every time.
That’s crucial for fairness, repeatability, and making confident hiring decisions at scale.

HeyMilo offers scoring, but the underlying consistency isn’t clearly defined. That may be fine for small teams — but if you're scaling hiring across multiple locations or recruiters, reliability matters.

🛠 Beyond the Interview: Automation That Closes Gaps

Both Tenzo and HeyMilo integrate with leading ATS platforms like Lever, Bullhorn, and Greenhouse. But Tenzo doesn't stop at syncing results — it powers your entire front-end funnel:

HeyMilo’s strength is in recruiter analytics and engagement tools — but it doesn’t automate these downstream workflows. Tenzo does. The difference is a system that screens and moves candidates forward on your behalf.

🌎 Multilingual Talent, One Platform

Both platforms offer multilingual capabilities, but Tenzo adds an important feature: live language switching during the call.

That means candidates can begin in one language and switch mid-interview if needed — a major advantage for global teams, field workers, and roles where English isn’t the primary spoken language.
