An interviewer that goes deep
No generic questions. Rcruit’s interviewer reads your job description, builds a tailored evaluation rubric, and asks probing follow-ups that mirror how real hiring panels assess candidates — on camera, in the same video format most recruiters now use.
Rubrics built from your actual job description
Rcruit extracts the skills that matter from the role and generates scored criteria with anchor scales — the same framework real interviewers use to calibrate hiring decisions. You’ll see exactly what ‘good’ looks like before you start practicing.

Feedback that tells you exactly where you stand
Most candidates never learn why they were rejected. Rcruit closes that gap. After each session, get a detailed scorecard with evidence from your actual answers — verbatim quotes mapped to criteria, scored against the rubric, with coaching tips to improve.
