Description

Streamline interview feedback handling with this rejection-focused workflow. It processes raw interview feedback, applies an AI-powered scoring model, checks against a threshold, and automatically sends polite rejection emails while logging tasks in ClickUp—ensuring consistent, hands-free candidate management.

What This Template Does

📋 Pulls raw feedback data from Google Sheets
🧠 Uses GPT-4o-mini to structure and score candidate profiles
⚖️ Applies threshold check (average score > 3.1 = pass, else reject)
🔀 Routes candidates via decision branch (pass = no action, fail = rejection)
📩 Sends templated rejection email via Gmail
🗂 Creates ClickUp task for rejection tracking (7-day due date)
