AI interviewer

Screen candidates at scale, or let people rehearse against a realistic interviewer. The identity does the asking — you just start a session and join.

The identity​

The whole behavior lives in the prompt.

curl -sS -X POST https://api.lookalike.com/v1/identities \
  -H "Authorization: Bearer $LOOKALIKE_API_KEY" \
  -F "name=Interviewer" \
  -F "prompt=You are a calm, professional interviewer. Ask one question at a time and wait for the full answer before responding. Never interrupt. Ask a short follow-up when it helps, then move on. Keep your own turns brief." \
  -F "image=@interviewer.jpg;type=image/jpeg"
# -> { "identity_id": "id_...", "status": "ready" }

The session​

curl -sS -X POST https://api.lookalike.com/v1/sessions/start \
  -H "Authorization: Bearer $LOOKALIKE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "identity_id": "id_..." }'

Make it feel right​

Let silences breathe. The hardest part of an interviewer is not cutting the candidate off while they think. The agent waits for a full turn before it replies, so avoid adding client-side timeouts that end a turn early.
