AI-powered Candidate Screening & Interview Scheduling with OpenAI GPT & Google Suite

Streamline your hiring process with intelligent AI-powered candidate screening and automated interview scheduling. This workflow receives applications via webhook, evaluates candidates using OpenAI's GPT model, scores them against job requirements, stores data in Google Sheets, and automatically schedules interviews for high-scoring candidates — all while sending personalized email notifications and updating statuses in real time. Reduce manual screening time and ensure only top candidates move forward. 🤖📧

What This Template Does

Step 1: Triggers on new application submission via Webhook (e.g., from job portal or form).
Step 2: Stores applicant data (resume, contact, role) into Google Sheets for centralized tracking.
Step 3: Uses OpenAI GPT to evaluate candidate fit based on resume, skills, and job requirements.
Step 4: Applies Scoring Logic:
  • Score ≥ 70 → Qualified for interview
  • Score < 70 → Not a fit
Step 5: Branches based on score:
  → High Score Path:
   • Sends Interview Invitation Email
   • Creates Google Calendar Event
   • Updates Sheet: Status → “Interview Scheduled”
  → Low Score Path:
   • Sends Polite Rejection Email
   • Updates Sheet: Status → “Rejected”
Step 6: Final metrics logged and webhook response confirms completion.
