Watch out for
  • No real-time path at all
  • Credit pricing makes per-candidate cost awkward to model
  • At roughly $1/min it is 200× the cost of Homo 1 — model your per-interview cost before committing
  • Recording a candidate’s webcam raises consent and data-retention obligations; several jurisdictions require explicit notice for automated video assessment
  • A trained replica of a real employee needs that employee’s written consent
