AI WhatsApp Job App Collector: Automate with n8n & Google Sheets

Transform your WhatsApp Business number into an intelligent job application collector that automatically gathers candidate information through natural AI-powered conversations and saves everything directly to Google Sheets—no forms, no manual data entry required.

What this workflow does

This n8n automation workflow creates a seamless WhatsApp-based recruitment system. When candidates message your WhatsApp Business number, an AI agent powered by GPT-4.1-mini initiates a conversational interview, intelligently collecting essential applicant details including first and last name, phone number, department and tech stack preferences, years of experience, and graduation year. All responses are automatically appended as new rows in your Google Sheets spreadsheet, creating an organized candidate database without any manual intervention.
