The recruitment process today faces significant challenges including time-consuming manual resume screening, inconsistent candidate evaluation, and high susceptibility to unconscious bias. Traditional Applicant Tracking Systems (ATS) often rely on rigid keyword matching that fails to understand semantic context, leading to qualified candidates being overlooked. This paper presents an AI-powered Resume Analyzer that leverages Natural Language Processing (NLP) and machine learning to automate and enhance recruitment workflows. The system extracts text from PDF and Word documents, performs comprehensive analysis including skill gap identification, keyword matching, and semantic similarity scoring, and provides actionable insights through interactive visualizations. Built using Python and Streamlit, the application serves both recruiters seeking to efficiently identify top talent and job seekers aiming to optimize their resumes for ATS compatibility. Experimental results demonstrate significant improvements in screening efficiency (85% time reduction), evaluation accuracy (92% consistency), and candidate-job matching precision compared to traditional methods.

Conclusion
This paper presented an AI-powered Resume Analyzer that leverages Natural Language Processing and machine learning to streamline the recruitment process and improve hiring outcomes. The system successfully addresses key challenges in modern recruitment by automating resume screening, providing objective candidate evaluation, and offering actionable insights for both recruiters and job seekers. Through the integration of advanced text extraction, NLP analysis, semantic matching via machine learning and LLMs, and comprehensive data visualization, the system delivers analysis that goes far beyond traditional keyword-based approaches.
Experimental results demonstrated significant improvements across all evaluated metrics compared to traditional manual screening and basic ATS systems. The 85% reduction in processing time (from 15.5 to 2.3 seconds per resume) enables recruiters to handle dramatically larger applicant volumes while maintaining or improving evaluation quality. The 92% matching accuracy and 98.5% consistency rates indicate that the system provides reliable, objective assessments that reduce the impact of human bias and fatigue. User satisfaction scores of 4.6/5.0 confirm that the system delivers real value to both recruiter and candidate stakeholders.
The implementation demonstrates that combining state-of-the-art NLP techniques with user-friendly web interfaces can make sophisticated AI capabilities accessible to non-technical users. The Streamlit-based interface requires no technical expertise to operate, while the underlying pipeline leverages advanced technologies including spaCy for NER, scikit-learn for machine learning, and optional LLM integration for semantic understanding. This combination of simplicity and power enables organizations of all sizes to benefit from AI-powered recruitment optimization.
