A note before you read: we wrote this comparison, and NTRVSTA is one of the two companies in it. For Mercor, we used only Mercor's website, its blog, its talent policies and TechCrunch's report on its funding. The links are at the end.
The short answer
Many employers who search for the Mercor AI interview want to run AI interviews on their own applicants. That's not what Mercor sells today. Mercor uses its AI interviewer to vet experts for its own marketplace, and it sells human data, evals and embedded engineers to AI labs and enterprises. Choose Mercor if you want vetted domain experts or training data delivered. Choose NTRVSTA if you want to put your own candidates through a live, adaptive AI interview, with resume scoring and public pricing.
Side by side: Mercor AI interview vs NTRVSTA
How NTRVSTA works
NTRVSTA is a tool your recruiting team runs. Resumes come in and get scored against the job description, so the strongest applicants rise to the top. You invite them to a live AI interview that runs 24/7. The interviewer is a video avatar or an audio voice, set per role, and it can carry your brand and speak multiple languages.
Unlike a fixed script, the interview moves with the candidate. A sharp answer brings a harder follow-up. A shaky one brings a question pitched where they can show what they know. The exam library spans coding languages, frameworks, AI/ML and DevOps, a whiteboard for system design, and soft skills like leadership, all with STAR behavioral questions and optional hints. When it's done, you get scores for technical skills, English proficiency and communication, clips of key moments and a shareable report.
How Mercor works
Mercor now describes its mission as "organizing human intelligence to power the AI economy." Applicants upload a resume and take a short AI interview, which Mercor says lasts about 20 minutes. Per Mercor, the AI interviewer writes its questions from the resume and job description, transcribes the answers and evaluates them. Experts who pass join a pool and get invited to paid AI-training projects. Mercor lists expert rates averaging around $98 an hour, with listed roles from $60 to $98 an hour.
Mercor's earlier blog described employers watching AI interviews and hiring candidates through the platform. The current site sells human data, evals and embedded engineers instead. TechCrunch reported on October 27, 2025 that Mercor raised a $350M Series C at a $10B valuation. Mercor names Harvey, Ramp, Cognition and Sierra as partners on its APEX benchmark.
On data handling, Mercor links a security and trust portal and says automated anonymization masks more than 60 categories of sensitive identifiers. It doesn't name certifications on its homepage, and we didn't find a published bias audit.
When Mercor is the better choice
- You need domain experts for AI-training work, and you'd rather pay for vetted people than build a pipeline.
- You're an AI lab buying human data or model evaluations, which is Mercor's core business.
- You want embedded engineers supplied, not a tool for interviewing your own hires.
To be fair about our side: NTRVSTA gives you software, not people. It handles screening and interviews and leaves the rest to your ATS, which you keep. Our native ATS connections are fewer than the large suites offer, and the API isn't out yet. Teams hiring hourly staff by SMS and chat scheduling will be better served by Paradox or Fountain, and teams who want humans to conduct the interviews should look at a Karat-style service. We're also smaller and newer than many vendors you'll compare us with.
Pricing compared
Mercor doesn't publish software pricing. The dollar figures it does show are expert pay rates, around $98 an hour on average, which tell you what talent earns rather than what a client pays.
NTRVSTA's plan prices sit on our pricing page. Audio interviews use 1 credit per minute and avatar interviews use 3 per minute.
- Free Demo: $0 for 50 credits, 1 concurrent interview.
- Starter: $299/mo for 1,500 credits (about 30 interviews).

The worked example on our site: Growth at 80 interviews a month is about $8.74 per interview, or $0.35 per minute. Twenty-five minutes of audio costs 25 credits, and 25 minutes with an avatar costs 75.
