Most newer LLMs are by default multimodal and we'll use Google's Gemini here as an example. By processing each candidate's resume as an image, we avoid scenarios where text extraction fails due to layout issues or by picking up \"hidden\" or malicious prompts planted to subvert AI automated processing.\n\nThis vision model ensures the resume is read and understood as a human would.
