Pick micro1 if you are an AI lab or agency buying expert human data, training environments or agent evaluations. micro1 no longer sells interview software.

The same tool, used from opposite sides of the table
Both companies run an AI interviewer, which is why the pair gets searched together. Eightfold rents its interviewer to employers: you load a role, invite your applicants and read the summaries. Its homepage says the AI never decides and your recruiters do.
micro1 points its interviewer at a different crowd. Zara screens engineers, lawyers, clinicians and linguists who want paid work training AI models, and certification only makes them eligible for projects. If you are a company with open roles, there is no micro1 product page that lets you put Zara in front of your own applicants.
What each interview asks of the person taking it
Both describe their interview in their own words. Steps 1 to 3 are Eightfold's; steps 4 and 5 are micro1's.
- Eightfold: an invite from the employer The candidate gets a link from the hiring company or enters through its ATS, then takes the interview at any hour that suits them.
- Eightfold: one session, several rounds The 360 Interview folds functional, coding and language checks into one sitting. Eightfold says a skilled trades evaluation takes 20 to 25 minutes and engineering always includes coding.
- Eightfold: judged on what was said Its FAQ says the AI does not analyse facial expressions, tone of voice or accent. Fraud checks watch for tab switching and duplicate voices, and ID.me or CLEAR confirm identity.
- micro1: practise, then meet Zara Applicants can rehearse with micro1's Interview Prep tool, then sit the real interview on demand, choosing one core skill to be judged on.
- micro1: a result in real time The applicant learns straight away whether they met micro1's global certification criteria. Human recruiters then match certified people to projects; certification alone guarantees no work.
Choose Eightfold if, choose micro1 if
Do
- You want an AI to run first round interviews on applicants for your own open roles
- Your hourly or frontline roles draw hundreds of applicants and recruiters cannot screen them all
- You also want sourcing, internal mobility and offers on the same skills model
- Legal needs a published bias audit before any AI interviews a candidate
Do not
- You train frontier models and need expert human data in law, medicine or finance
- You need reinforcement learning environments that mirror real work tasks
- You run agents in production and want them evaluated against real context
- You are a US agency looking for screened experts through the Tradewinds marketplace
Four buyers who land on this comparison
The search is the same; the reason behind it usually is not.
A retailer has 500 applicants for seasonal store roles and 3 recruiters to get through them.
Eightfold. Its homepage describes AI Interviewer interviewing the candidates you invite and summarising each one for high volume hourly roles.
Ask how the summaries reach your ATS and who sees the recordings.
A lab needs 200 practising lawyers to write and grade legal reasoning tasks for a new model.
micro1. It publishes a legal reasoning benchmark and recruits domain experts for exactly this kind of human data project.
Ask how many certified experts are active in your jurisdiction today.
A manufacturer is opening sites in 4 new countries and has to interview in local languages.
Eightfold. Its AI Interviewer lists more than 20 languages and CEFR based language checks inside the interview.
Confirm each language you need is live, not on a roadmap.
A recruiter remembers micro1 selling an AI recruiter and wants it for their own pipeline.
Neither micro1 page offers that today. Its site sells data work, and Zara screens micro1's own applicants.
Look at AI interview software sold to employers instead.
A verified plus and minus for each company
- Eightfold strength: its AI Interviewer runs on your applicants, with a published NYC Local Law 144 bias audit
- Eightfold limit: no pricing page, so every evaluation starts with a demo and a scoped quote
- micro1 strength: an expert network it describes as 130,000+ candidates across 100+ domains and 60+ languages
- micro1 limit: no product on its site lets an employer interview its own applicants with Zara
How Eightfold and micro1 differ in day to day use
With Eightfold, your recruiters log in. They open a requisition, see who the AI Interviewer has spoken to, read the summary and recording, and advance people in the same platform where they source and make offers. Eightfold says activation takes 1 to 2 weeks and the interviewer works alongside your existing ATS.
With micro1, nobody on your side touches an interview. You scope a dataset, an environment or an evaluation with its researchers, and micro1 recruits, trains and manages the experts. Its government page describes reviews by domain experts, managers and human data leads before data is delivered, plus live tracking of error rates and cost per task.
Questions to ask before you sign with either
Neither company prints a price, so the first call has to do the work a pricing page would.
- Eightfold: is AI Interviewer priced per interview, per hire or as part of a platform licence?
- Eightfold: can we buy AI Interviewer alone, without Talent Acquisition?
- Eightfold: may we read the latest bias audit before the contract?
- micro1: is the work priced per expert hour, per task or per dataset?
- micro1: who owns the data, prompts and outputs the experts produce?
- micro1: how are experts checked beyond the Zara interview?
If you want an AI interview on your own roles without an enterprise rollout
A live AI interview report: each criterion scored 1 to 5, overall written feedback, the transcript and the recording.
Readers who came for micro1's interviewer and find Eightfold too large have a smaller option. The Cognitive runs a live 10 or 20 minute AI video interview on your roles, and it can first find people across ~900M public profiles with verified emails and phones. Results reach your ATS as a note through 60+ integrations.

Frequently asked questions
Is Eightfold better than micro1?
They do different jobs, so better depends on what you are buying. Eightfold sells employers an AI Interviewer and a talent platform for sourcing, interviewing, internal mobility and planning. micro1 sells AI labs and agencies expert human data, training environments and agent evaluations. If you need your own applicants interviewed, only Eightfold offers that on its site.
Can I use micro1's Zara to interview my candidates?
Not from what micro1's site offers on 5 October 2026. Zara is described as micro1's AI recruiter for people applying to its expert network, and the company pages list data partnerships and government work. There is no product page or plan that puts Zara on an employer's own roles.
Eightfold vs micro1 pricing: how does each charge?
Neither publishes a price. eightfold.ai/pricing returns a 404, and buyers go through a live demo and a quote. micro1.ai/pricing redirects to the homepage, where companies describe their project in a contact form. Ask Eightfold whether AI Interviewer is sold on its own, and micro1 whether work is priced per task or per expert hour.
How does the Eightfold AI Interviewer work?
You send candidates an invite link or connect your ATS. The AI holds an adaptive conversation at whatever time suits the candidate, and its 360 Interview can cover functional, coding and language rounds in one session. Recruiters get summaries and recordings and make every decision. Eightfold lists 12+ fraud signals and identity checks through ID.me and CLEAR.
Does micro1 still do AI recruiting?
micro1 now describes itself first as a data lab for training frontier models and testing agents. Recruiting survives inside the business: Zara interviews and certifies the experts micro1 places on data projects, and its government page describes an AI recruitment engine behind its expert network. It does not sell that engine as recruiting software.
Do Eightfold and micro1 publish bias audits?
Eightfold says independent auditors test AI Interviewer for bias under NYC Local Law 144 and links to the results, with a separate matching model audit. micro1's expert page says certification rests on demonstrated knowledge rather than background or location, and that human recruiters review profiles. The pages read do not link a third party audit for Zara.
Which has the bigger talent pool, Eightfold or micro1?
They measure different things. Eightfold says its model draws on 1.6 billion career trajectories and 1.6 million skills, which describes training data rather than people you can contact. micro1 says 130,000+ screened candidates across 100+ domains and 60+ languages are ready to onboard to its projects. Neither number is a pool you search yourself.
