Automated Phone Interview Evaluation with Vapi, GPT-4o & Sheets

This n8n workflow automates the evaluation of phone interview transcripts received via webhook from systems like Vapi.ai. It leverages OpenAI's GPT-4o-mini to analyze candidate responses against predefined qualification criteria, such as skills, experience, and fit for roles like drivers or other positions. Key information including name, phone, location, and qualification status is extracted automatically.

The structured results are then saved directly to a Google Sheet, enabling easy review, follow-up, and reporting for HR departments and recruitment agencies. This eliminates manual transcript review, reduces bias, and speeds up screening by providing consistent AI-driven scoring.

Ideal for high-volume hiring in HR, ATS systems, or businesses conducting phone screens. Benefits include massive time savings, scalable evaluation, and actionable insights. Easily customizable for any job role by adjusting AI prompts. Prerequisites: n8n instance, OpenAI API key, Google Sheets, and webhook-enabled interview tool.
