Specialist AI Work is independent from Mercor. Some Apply links may be referral links, and we may be paid if the platform credits the referral. This does not change the pay shown in a role or how roles are ordered here.
Applicant workflow
Live roles remain the purpose of this page. This sourced summary helps you understand what can happen before and after a Mercor application.
Create or update a Mercor profile, open a current role, and submit the role-specific application requested on the official site.
Mercor documents role applications, profile information, and project-specific screening. Requirements can differ by opportunity.
Some applications use an AI interview or a role assessment. Follow the current instructions and use only assistance the platform explicitly permits.
An offer, platform acceptance, or completed interview does not by itself mean a project has started. Project onboarding can include additional documents or checks.
Mercor documents project onboarding, agreement signing, background checks for some work, and payment setup as separate steps.
A suitable project may not be available after profile or interview completion. Public documentation does not promise continuous matching, hours, or project duration.
Payment details are a separate intent from advertised listing rates. Compare documented providers, approval rules, and unknowns in the contractor payment guide.
Compare the current tracker snapshot, role mix, application steps, and platform cautions.
Compare current role coverage, pay evidence, fields, and screening context.
Compare current reviewed opportunities across the supported platforms.
Prepare for resumes, assessments, onboarding, identity checks, and unstable project access.
