Preparing the latest platform information for you.
micro1 is a human-data and recruiting platform that connects verified professionals with AI training projects. Contributors help improve AI models through tasks such as data annotation, prompt writing, response evaluation, and domain-specific reviews. The platform uses a role-based selection process, offers flexible remote opportunities, and matches certified experts to projects based on skills and client demand .
Good English & Clear Communication: You need to communicate clearly in English and explain your technical decisions and reasoning. Don't just give the answer — explain why you chose it.
Know Your CV: Be ready to explain everything you mentioned in your CV, especially your projects, technologies, and responsibilities. You may be asked why you chose a specific architecture, technology, or approach and what trade-offs you considered .
If You Get a Coding Challenge: Focus on understanding the requirements before coding. Pay attention to correctness, edge cases, time and space complexity, and whether your solution handles different inputs properly.
If you want to restart the interview during the process, you can refresh the page and restart the interview from the beginning if needed. Try to stay calm and treat it like a conversation rather than a stressful exam.
Zara is micro1’s AI-powered interviewer. It conducts a conversational, role-specific assessment of communication, reasoning, and practical knowledge, with technical or human-data exercises when appropriate.
micro1’s referral FAQ says certification interviews normally take about 20–40 minutes, depending on the skills required. Some roles add a brief follow-up assessment.
Official guidance lists open-ended technical questions, scenario-based reasoning questions, coding challenges for technical roles, and human-data exercises for annotation roles.
micro1 says candidates receive a real-time result showing whether they meet its global certification criteria. If certification is not achieved, the candidate can request feedback.
Official guidance says certified experts are typically updated on their application status within 30 days. A match is not guaranteed, and the profile can remain active for future opportunities.
Official micro1 guidance lists typical ranges of $15–$40/hour for general annotation, $20–$60 for prompt writing and RLHF, $50–$100 for domain review, and $100–$200+ for frontier expert work. The actual rate appears on each role.
micro1 contractors are paid through Deel. Depending on country and Deel availability, withdrawal options can include a local bank transfer, Wise, or PayPal, with method-specific processing times and fees.
Many opportunities are flexible and compatible with other work or study, but minimum weekly commitments and schedules vary by project. Some roles are full-time, part-time, or pay per task.
Yes. micro1 encourages candidates to apply independently to suitable roles and certify additional genuine skills, which can increase the range of projects for which they may be considered.
The candidate privacy notice lists audio and video recordings, screen sharing for technical assessments, transcripts, scores, and performance analytics. Anonymized interview data may be used to improve AI models; candidates can request an opt-out where technically feasible.
As of July 23, 2026, Trustpilot displays 4.7/5 from 9,155 reviews. Many recent reviews discuss the Zara interview rather than completed paid projects, so the score is best treated as a broad candidate-experience signal.
