What this actually is
You review AI-generated code, rank model outputs against each other, write prompts that test edge cases, and provide expert feedback that gets used to train coding models. Not shipping production software. The platform title (Puzzle Solver (Coding)) reflects the rate band and the expertise required, not the day-to-day work.
How micro1 picks people
- Apply to the role, then do an interview with micro1's AI recruiter. It takes 20 to 40 minutes.
- Some roles add a short skills test after the interview.
- If you pass, micro1 asks you to finish your profile and verify your ID. You then join its certified pool and can apply to its other open roles.
Before you start
- Plan for 40 minutes in a quiet place.
- Have your CV and two or three examples of your own work in this field ready to talk about.
Not every applicant gets an offer. Prepare well for the interview.

• Analyze unfamiliar problems and translate their requirements into implementable solutions.
• Select appropriate algorithms, data structures, and problem-solving strategies.
Required Qualifications
• A Codeforces profife is a must
• Strong understanding of common data structures and algorithms.
• Ability to reason carefully about constraints, complexity, edge cases, and correctness.
• Experience debugging unfamiliar code or solving technically ambiguous problems.
A public or otherwise verifiable Codeforces profile demonstrating meaningful competitive-programming experience is nice to have.
Process
• Apply to the role and complete the screening questions.
• Complete an AI interview of approximately 30 minutes.
• Complete the hiring manager review.Compensation Structure
Compensation is output-based. Experts are paid per task that meets the project specifications. The time required to complete each task may vary depending on the expert’s experience and workflow.
