What is RAG Recruitment Assistant?

The RAG Recruitment Assistant is an innovative “Reverse Matching” system built on Retrieval-Augmented Generation (RAG) architecture. Unlike traditional recruitment systems that filter candidates by years of experience, this system focuses on identifying talent based on:

Technical Potential

Evaluates candidates based on their skill stack, technical proficiency, and demonstrated abilities rather than tenure

Academic Projects

Values hands-on project experience, hackathon achievements, and academic work as key indicators of capability

Smart Matching

Uses AI to understand context and match candidates to roles based on semantic similarity, not keyword matching

Explainable Results

Generates natural language justifications for why each candidate is a good fit

The Reverse Matching Approach

Traditional recruitment systems filter candidates using rigid criteria like “5+ years of experience” or exact job title matches. The RAG Recruitment Assistant flips this paradigm:
Reverse Matching means the system doesn’t ask “Does this candidate meet our requirements?” but instead asks “What valuable potential does this candidate have, and where would they excel?”
This approach is especially valuable for identifying:
  • Recent graduates with strong academic projects
  • Career changers with transferable skills
  • Self-taught developers with portfolio work
  • Students seeking internships or entry-level positions

RAG Architecture Overview

The system implements a complete RAG pipeline optimized for recruitment:
1

Document Ingestion

PDF resumes are loaded and parsed to extract text content, preserving structure and metadata
2

Vector Embedding

Text is converted into high-dimensional vectors using HuggingFace’s sentence-transformers, capturing semantic meaning
3

Vector Indexing

FAISS (Facebook AI Similarity Search) creates an efficient index for fast similarity search across thousands of candidate profiles
4

Semantic Retrieval

When a job requirement is submitted, the system finds the most semantically similar candidate profiles
5

Context-Aware Generation

Retrieved candidate data is passed to Gemini 1.5 Flash LLM, which generates detailed explanations of why each candidate is suitable

Target Audience and Use Cases

Who Should Use This System?

Help match graduating students with internships and entry-level positions based on their academic projects, thesis work, and technical skills rather than non-existent work history.
Fast-growing companies that need to identify high-potential junior talent who can learn quickly, even if they lack traditional experience markers.
Organizations that want to demonstrate graduate outcomes by matching learners to opportunities based on portfolio projects.
Recruiters looking to reduce bias by evaluating candidates on demonstrated skills rather than pedigree or years of experience.

Primary Use Cases

  1. Internship Placement - Match students to internships based on academic projects and skill alignment
  2. Junior Role Screening - Identify entry-level candidates with the right technical foundation
  3. Project-Based Evaluation - Assess candidates by the complexity and relevance of their portfolio work
  4. Skills Gap Analysis - Understand what technical capabilities candidates possess beyond their job titles

Key Differentiators

This system is not designed to replace human recruiters. Instead, it augments human decision-making by providing AI-powered insights and reducing initial screening time.

Project Context

This project was developed by Anghelo Mendoza Prado as a practical demonstration of applying Generative AI and RAG architecture to solve a real-world talent selection problem.
The system was originally developed and tested in Google Colab, making it accessible to anyone with a browser and a Google API key. It can also run locally with Python 3.10 or 3.11.
