Demographic questions are the voluntary self-identification prompts applicants see on job posts and candidate surveys (separate from the EEOC questionnaire, which carries its own legally-mandated wording). Each question belongs to a demographic_question_set, has a single- or multi-select answer_type, and pulls its choices from demographic_answer_options. The set returned here includes both organization-defined custom questions and Greenhouse-provided U.S. Standard Demographic Questions; standard ones are not editable.
