What This Workflow Does

• Collect Inputs: Start by collecting resume PDFs and a job description through a seamless n8n form submission.
• Generate Job Description Embedding: Utilize OpenRouter’s embeddings endpoint with `openai/text-embedding-3-large` to create a detailed embedding of your job description.
• Process Resumes: Each resume PDF is converted to text using n8n's built-in PDF extraction capabilities.
• Handle Scanned Documents: For texts that are too short due to scanning, the workflow uses OpenRouter chat completions and the `file-parser` plugin (`mistral-ocr`) for OCR and retrieves plain text.
• Generate Resume Embeddings: Create an embedding for each resume using `openai/text-embedding-3-large`.
• Rank Resumes: The workflow calculates cosine similarity between each resume’s embedding and the job description embedding, sorting them from most similar to least similar.
• Output Results: Finish with a CSV-style list showcasing ranked resumes by filename.
