Interviewer tags are organization-defined labels assigned to interviewer users, such as "Bar Raiser," "Diversity Trained," or "Senior." They are surfaced as Interviewer Groups in the Greenhouse UI and used by schedulers to narrow the pool of interviewers when selecting one for a stage. A user can belong to multiple tags. To find which tags are assigned to a given user, request the interviewer_tags field on GET /v3/users.
