🛠️ How It Works

Trigger: Workflow is initiated via a Webhook (from a UI “Start Workflow” button).

CV Search: Searches for CV files in a designated Google Drive folder.
Loop Over Files:
Each file is downloaded.
Text is extracted (from PDFs or other formats).
Criteria Input: Matching rules are fetched from a predefined Google Sheet.
Merge & Aggregate: Combines file text and criteria for unified processing.

LLM Processing:
Text + criteria are sent to the Basic LLM Chain.

Utilizes Ollama Model for advanced language understanding.

Structured or auto-fixing output parsers enhance reliability.

Custom Code Execution: Optionally enriches or reformats the data.

Output: Results are appended to a shared Google Sheet (the output sheet).
