About This Workflow
Overview
This n8n workflow is designed to automate the process of analyzing candidate resumes, particularly in scenarios where resumes might contain "hidden prompts" intended to manipulate or bypass Applicant Tracking Systems (ATS) or other automated processing. The core logic involves converting a PDF resume into an image format, which is then processed by a Vision Language Model (VLM). This approach ensures that the resume is analyzed visually, as a human would read it, making it resilient to text-based manipulation tactics. By using a VLM, the workflow aims to provide a more accurate and robust assessment of a candidate's suitability for a role.
Key Features
- Downloads candidate resumes from cloud storage (e.g., Google Drive).
- Converts PDF resumes into image format using a dedicated API (Stirling PDF).
- Resizes converted images to optimize processing time for the VLM.
- Utilizes a Vision Language Model (e.g., Google Gemini) to analyze the resume image.
- Parses the VLM's output into a structured format to determine candidate qualification.
How To Use
- Configure the 'Download Resume' node to point to your candidate's PDF resume file (e.g., via Google Drive).
- Set up the 'PDF-to-Image API' node with the correct endpoint for your Stirling PDF instance or a similar PDF-to-image conversion service.
- Configure the 'Resize Converted Image' node to adjust the image dimensions as needed.
- Connect the 'Candidate Resume Analyser' node to your chosen Vision Language Model (e.g., Google Gemini Chat Model).
- Define the prompt and schema for the 'Candidate Resume Analyser' to instruct the VLM on how to assess the resume and what output to provide.
- Use the 'Structured Output Parser' node to interpret the VLM's response into a usable format.
- Implement the 'Should Proceed To Stage 2?' node to branch your workflow based on the analysis results.
