Additional platform screening, payment, availability, and review details
Comparison fact	Mercor	Handshake	Micro1
Payment details	An accepted offer opens payment setup; Mercor documents Stripe as the normal path and Wise as a fallback in some countries or corridors, with matching legal names for KYC.	Handshake says onboarding includes tax details and Stripe payout setup; payouts usually go to partner pay platforms by Wednesday afternoon and may take about 48 hours, with project-specific terms taking precedence.	Micro1's public flow places onboarding after the AI interview and before earning; confirm the current contract and payment setup in the expert dashboard or accepted-project terms.
Screening	Open a current role in Mercor's Explore view Submit the resume, required form or AI interview, and work-authorization details shown for that role A role may combine a resume, written/form assessment, AI interview, and work-authorization check; requirements vary by role.	Create or sign in to a Handshake account and open AI Work Verify your phone, work authorization, profile, resume, and required agreements The application collects expertise, resume, work-authorization answers, and agreements; some projects may add evaluations, training exercises, or portfolio reviews.	Apply to an open opportunity or validate a skill on Micro1's expert page Complete the AI interview and structured skill validation shown for the opportunity Applicants can validate a skill or apply to an open role, then complete the AI interview and structured skill validation; human recruiters also review profiles against project requirements.
Project availability	A listing or completed assessment is not an offer of work. Project onboarding and tool access follow selection and offer steps, and task access can pause or change.	Applications are reviewed on a rolling basis, but submitting one does not guarantee placement; invitations depend on current partner demand, project availability, qualifications, and fit.	Certification or onboarding makes a profile eligible for consideration, not immediate placement; invitations depend on verified skills and project availability.
