Record an interview that is already scheduled on an external calendar against a candidate's application at a specific slot on the job's interview plan. This endpoint does not create a calendar event or send calendar invites to interviewers or the candidate: create the event and send invites through your own calendar integration, then pass that event's id as external_event_id. Greenhouse scorecard reminders still apply to the recorded interview. application_id, job_interview_id (the interview-plan slot), starts_at, ends_at, and external_event_id are required. Provide the panel via interviewers, where each entry must include response_status and identify the interviewer by user_id, email, or employee_id. organizer_id optionally records a specific Greenhouse user as the organizer and defaults to the authenticated user. location and video_conferencing_url are optional metadata copied onto the Greenhouse record.
