Sophia — executive overview

Sophia lets hiring teams run AI-led interviews: create a role, add candidates, schedule sessions, and receive scored reports. Usage is paid with prepaid credits (packs via checkout). The recruiter web app talks to a central backend over HTTPS; the live AI interviewer runs as a separate service. For implementation detail, see the technical system overview.

Typical interview (happy path)

1. Recruiter signs in, creates a position and candidate (optional resume upload).
2. They schedule an interview; the platform reserves credits and sends an invitation link.
3. Candidate opens the link, verifies access, and consents if required.
4. The AI bot runs the session in a video room; the backend tracks status.
5. When the interview ends, credits are settled and report generation is queued.
6. A background worker produces the report; the recruiter views it in the app.
