Mercor runs AI-led voice interviews, reported by candidates and coverage as roughly twenty minutes, used to vet professionals for project work. Check your invitation for the exact format of your role: the company's focus and products changed during 2025 and 2026, so older preparation posts may describe a process that no longer applies. Retake and scoring rules are not fully published; treat specific numbers on preparation blogs as unverified unless Mercor states them.

Prepare the way the format rewards#

A short AI voice interview compresses everything into spoken answers. Build three stories from your own work that each show a decision, your personal action and evidence of the result. Practise saying them aloud against a timer, because a silent pause costs more in a twenty-minute format than in an hour with a human. The story-map worksheet organizes the facts; the free preparation preview turns one story into rehearsal questions.

Check terms and your data#

Read Mercor's current candidate terms before the interview, including how long recordings are kept and how your data is used; press coverage in 2026 reported a security incident at a vendor that exposed contractor recordings, so it is reasonable to ask any AI interview provider what is stored and for how long. Keep your own rehearsal material out of the assessment itself unless the rules allow assistance, and rehearse the format with our Zara-format practice tool, which uses original questions and works for any AI-led voice interview.
