Interview preparation journey

Journey
In my preparation journey, I focused primarily on the projects I have worked on, both within my company and through personal initiatives. I reviewed the problem statements, design choices, and challenges I encountered, making sure I could clearly explain my contributions and outcomes. Alongside this, I revised the core technologies I applied in these projects—such as Spring Boot, React, and AI/ML tools—so that I could relate technical concepts to practical implementations. This project-oriented preparation gave me the confidence to discuss my work in detail and connect it to the interview scenarios.
