How to Prepare ATS Data for AI Models and RAG with

Unified.to’s guide explains how teams can prepare applicant tracking system data for AI models, candidate-job matching, ranking tools, and retrieval-augmented generation by retrieving standardized jobs, candidates, applications, interviews, and documents through its ATS API and storing all training data, embeddings, and features within their own infrastructure. It emphasizes that ATS data is incomplete and varies substantially by integration, so developers should not assume resumes, skills, hiring outcomes, offer acceptance, filters, incremental updates, or stage-transition histories are consistently available. A reliable dataset joins candidates and jobs through applications, derives features from relatively common fields such as job descriptions, experience, education, titles, application answers, and customer-managed metadata, and treats resumes and skills as optional enrichment. Labels should be created only from observable outcomes such as hiring and rejection timestamps or accepted offers, with missingness and label sources retained for honest evaluation. The recommended workflow includes paginated initial backfills, local storage, privacy-conscious removal of direct identifiers, incremental synchronization using update timestamps or events where supported, recomputation of changed features, and scheduled retraining. AI outputs should remain tied to available evidence, such as matching scores, rankings, similar-candidate retrieval, conversion insights, and next-action recommendations, while clearly disclosing integration-specific gaps to users.
