Final answer:
An applicant tracking system used by federal contractors must track applications, résumés, job postings, job descriptions, EEO data, and applicant flow data to comply with federal regulations.
Step-by-step explanation:
As a federal contractor, an applicant tracking system (ATS) must track various elements essential for compliance with regulations and reporting requirements. One of the key elements it must track is option C, which includes applications, résumés, job postings, job descriptions with basic qualifications, EEO data, and applicant flow data.
These components are vital for ensuring that the hiring process is equitable and meets the federal guidelines set for contractors. Applicant tracking systems are used to streamline the recruitment process by managing these elements efficiently, aiding compliance, and providing insights for improving the hiring strategy.
