The Fake ATS API provides a comprehensive simulation of a real applicant tracking system, enabling developers to build, test, and demonstrate recruitment workflows. It supports entity management such as companies, job openings, candidates, applications, interviews, and skill assessments. The API is built with Laravel, offering endpoints for creating, updating, and retrieving data related to recruitment processes. It is ideal for MCP server testing, training workshops, and development environments without requiring access to a live system, streamlining the process of integrating and testing various recruitment functionalities.
