AI-Powered ATS Resume Screening Bot (Telegram + n8n + Gemini)📋

AI-powered ATS resume screening system built with Telegram, n8n Agentic AI, and Google Gemini. Automatically processes PDF/ZIP resumes, extracts candidate details, generates ATS scores with LLM evaluation, and logs eligible profiles into Google Sheets for seamless HR and placement workflows.

Quick overview

This project automates early-stage hiring by evaluating resumes with an LLM-driven ATS evaluator. Candidates upload a single PDF or a ZIP of resumes via Telegram; n8n handles file extraction, agentic prompt construction, and Google Gemini evaluation. Results (Name, Email, Mobile, ATS_Score) are written to Google Sheets and candidates are auto-classified (Accepted if score > 70), and also check ATS score of you resume

• Agentic AI prompts (n8n LangChain node) → Google Gemini LLM
• Returns structured JSON: { "Name", "Email", "Mobile No", "ATS_Score" }
