Ethos

Pay

$70 to $350 an hour

Hiring speed

Can be days (we were interviewed and hired in 3)

Best for

Experts who want the highest hourly rates

How hiring works

You interview with Ethos, an AI recruiter. There is no single sitting: you can keep talking to her as long as you like, and the more you tell her about your work, the more projects she matches you to and puts forward to human reviewers who make the hire.

• Go back for more conversations. Detail about your real experience is what gets you matched.
• Pay is the highest of the three platforms here.

Worth knowing: Projects are short. People commonly report 6 to 12 weeks before a project ends or they are offboarded, so treat it as high-paying contract work, not a steady job.

How hiring works

Apply with your background and complete the assessment or AI interview for a role. Your work quality on each project decides how often you are invited back.

• Once you are in and do well, Mercor keeps inviting you to new roles.
• Wide range of work, from generalist evaluation to specialist projects.

Worth knowing: Honestly, landing a first role with a fresh profile is hard. Apply to several roles that closely match your background.
