What Is Resume Deduplication Software?
Resume deduplication software is a tool designed to automatically identify and merge duplicate candidate profiles within a database, such as an Applicant Tracking System (ATS) or CRM. It is crucial for maintaining a clean, efficient, and accurate talent pool. By preventing recruiters from contacting the same candidate multiple times, it ensures a single source of truth for candidate history, improves the overall candidate experience, and enhances the effectiveness of sourcing and reporting. The best software uses advanced AI to identify duplicates even with different contact information or resume formats.
