Abstract: The growing demand for software engineering talent has highlighted the limitations of traditional coding preparation platforms, which often lack personalization, focus, and real-time guidance. This paper presents Career Navigator, a modern, AI-powered e-learning platform tailored for coding interview preparation. Unlike conventional systems, Career Navigator integrates a curated repository of company-specific questions, a multi-language online code editor, and a real-time AI chatbot assistant. Built on a scalable web architecture using technologies like Next.js, MongoDB, and Gemini API, the platform provides a seamless, distraction-free learning experience. Features such as personalized progress tracking, gamified learning paths, and integrated code execution make Career Navigator a comprehensive solution for effective, efficient, and adaptive coding practice. The results demonstrate improved user engagement, reduced preparation time, and higher interview readiness, particularly for candidates targeting top-tier tech companies.
