The short answer: the micro1 AI interview is a spoken conversation with Zara, micro1’s AI recruiter, that you can take whenever you like. Zara asks technical and scenario questions tailored to the area of expertise you pick, adapts to your background, and evaluates how you think, solve problems and communicate. Technical roles add a coding challenge and annotator roles a human data exercise. You get a result on the spot telling you whether you meet micro1’s certification criteria. micro1 offers free 18-minute practice interviews, and its privacy notice says a human evaluator reviews the overall assessment before a final decision. The best preparation is to choose one skill you’re strongest in, practice explaining your reasoning out loud, and know your own work in depth.
Everything about micro1 below comes from micro1’s own pages, its candidate privacy notice and published reporting, with sources at the end.

How the micro1 AI interview works
micro1 says every candidate goes through the AI interview, which it describes as a way to assess real-world skills in a fair, fast and structured way. You choose the skill or job type you want to be evaluated on, then talk with Zara by voice and camera. Expect open-ended technical questions about that field, scenario questions about how you’d handle real situations, and, depending on the role, a coding challenge (technical roles) or a human data exercise (annotator roles).
Automated tools handle screening, proctoring and an overall assessment, according to micro1’s candidate privacy notice, and a human evaluator reviews that assessment before a final decision is made. At the end you see whether you met micro1’s global certification criteria. If you didn’t, micro1 says you can request feedback.
micro1’s own interview pages don’t state how long the real interview lasts or whether you can retake it. Plan for at least the length of the practice interview, plus time for any exercise, and contact micro1 support if a technical problem interrupts you.
What Zara asks
micro1 says no two candidates receive the same questions, and that difficulty and scope vary with your field and experience. Its own sample questions show the pattern:
- Engineering roles get deep technical questions on architecture, problem-solving and reasoning about code, plus a coding exercise.
- AI trainer roles in a subject, such as physics, get questions at the level of that subject, plus an AI trainer exercise.
- Sales, marketing and project roles get scenarios from the job: a complex deal with conflicting stakeholders, a budget that has to move mid-quarter, a key person going on leave just before a deadline.
- Soft-skill scenarios appear too, such as how you handled a disagreement with a teammate.
Practice questions
We wrote these to match the kinds of questions micro1 describes. Practice them out loud, because Zara listens to how you reason, not just your conclusion.
About your expertise
- “Which skill did you choose for this interview, and what’s the hardest problem you’ve solved with it?”
- “Walk me through a project where you were the person others came to for answers.”
- “What’s something in your field that most people get wrong?”
Technical depth (adapt to your field)
- “Explain a concept from your field to someone smart who isn’t an expert.”
- “You have two ways to solve this problem. Compare their trade-offs and pick one.”
- “Something you built or delivered failed in production. How did you find the cause?”
AI trainer and annotation
- “Here’s an AI answer to a question in your field. What’s wrong with it, and how would you correct it?”
- “How would you write a grading rubric so two reviewers give the same score?”
- “When two guidelines conflict on a borderline case, how do you decide?”
Scenarios and soft skills
- “A teammate disagrees with your approach a day before a deadline. What do you do?”
- “You realize a task will take twice as long as promised. How do you handle it?”
- “Tell me about feedback that changed how you work.”
For stories, STAR (situation, task, action, result) keeps you in order; see our STAR method guide. For technical and annotation questions, use a simple frame instead: answer, reason, example.
How to prepare, step by step
- Pick the skill you’re strongest in. micro1 suggests choosing one core skill or job type to be evaluated on. Pick depth over breadth: Zara adapts its follow-ups, and a skill you only know on the surface won’t hold up.
- Take micro1’s free practice interview. micro1 lists 18-minute practice interviews across many fields, with feedback on your performance. Do one in the field you’ll be certified in.
- Know your own work in depth. Be ready to explain any project, tool or claim you mention, including why you made each decision.
- Rehearse thinking out loud. Explaining your reasoning as you go is what scenario and technical questions are built to hear. A mock interview with a live AI interviewer that asks follow-ups is close practice.
- Warm up for the exercise. If you’re a developer, solve a few timed problems in the language you’ll use. If you’re applying as an AI trainer, practice spotting and fixing errors in AI-written answers in your subject.
- Set up properly. Use a computer with a working camera and microphone, a stable connection and a quiet room. Technical assessments may record your screen, so close anything you don’t want on it.
- Keep it clean. The interview is proctored. Stay on the interview, don’t use notes or AI tools to answer, and say “I’m not sure” when you aren’t, then reason about it.
Your data, and the “AI training” question
A common worry among candidates is whether micro1 uses interviews to train AI. micro1’s candidate privacy notice, last updated July 21, 2026, answers it directly:
- What’s recorded: audio and video of your AI interview, screen recordings for technical assessments, transcripts, and assessment scores and results.
- Training: micro1 says it may use de-identified interview audio, video, transcripts and assessment results to train and improve its own machine learning models. It says it doesn’t share your data, de-identified or otherwise, with AI model companies to train their models.
- Opting out: you can opt out of AI training, delete your account or request a copy of your data through micro1’s account deletion page, or email micro1’s privacy team for other requests.
If that matters to you, opt out before or right after your interview rather than assuming the default suits you.
Is micro1 legit?
Yes, micro1 is a real, funded company, and its AI interview is how it vets the experts it hires as contractors.
- The company: in September 2025 TechCrunch reported that micro1 raised a $35 million Series A at a $500 million valuation, led by 01 Advisors. TechCrunch described it as helping AI companies find and manage human contractors for data labeling and training, and said Zara interviews and vets the candidates who apply to be micro1’s “experts”.
- The process: micro1 says a human evaluator reviews the overall assessment before a final decision, so the AI isn’t the only judge.
- The data trade-off: your recordings may train micro1’s own models unless you opt out, as described above.
As with any remote work platform, apply only through micro1’s own site, and never pay to get work. The FTC says honest employers will never ask you to pay to get a job.
micro1 vs Mercor: what’s different
