Default interviewers are the users pre-selected as the interview panel for a specific stage on a job. When a candidate reaches that stage, these users are auto-populated as interviewers on a new interview; the scheduler can still pick different people, so this list reflects the default, not the final panel. Each row pairs one user with one interview kit (a kit represents one stage's setup on one job). Defaults configured in the UI as interviewer groups or hiring-team roles are not exposed here — only rows backed by an individual user are returned.
