Increasingly companies are using third-party digital hiring platforms to recruit and select job applicants. These products, explicitly or implicitly, promise to reduce or eliminate the bias of hiring managers in making selection decisions. Instead, the platforms grade applicants based on a variety of purportedly objective factors. For example, a platform may scan thousands of resumes and select applicants based on education level, work experience, or interests, or rank applicants based on their performance on an aptitude test – whatever data point(s) the platform has been trained to evaluate based on the job opening.
