Automated Interview Scheduling: Sheets, Calendar, Gmail & GPT-4o

This n8n workflow revolutionizes interview scheduling for HR teams and recruiters. It triggers every minute to scan a Google Sheet for new candidate entries containing name, email, and background info. The automation intelligently selects the next available slot on Mondays, Wednesdays, or Fridays at 3 PM, ensuring no same-day bookings or conflicts.

Once a slot is identified, it creates a Google Calendar event with the candidate details and generates a professional, personalized invitation email using GPT-4o. The AI crafts concise, polite messages tailored to the candidate's background, eliminating manual email drafting. Finally, the invite is sent directly via Gmail, including the calendar link for seamless acceptance.

Benefits include massive time savings by removing back-and-forth emails, conflict-free scheduling, and a polished candidate experience. Ideal for startups, recruitment agencies, and busy HR professionals handling high-volume hiring. Requires Google APIs, Gmail OAuth, and Azure OpenAI credentials for plug-and-play setup.
