Interview preparation journey

Journey

I started by strengthening my HTML, CSS, and JavaScript skills, then focused on React, learning components, hooks, and state management. I built hands-on projects like forms, dashboards, and SPA apps to apply my knowledge. I practiced API integration, authentication flows, and debugging/testing using Jest. I also prepared for interviews by solving frontend-related DSA problems, reviewing performance optimization techniques, and studying common JavaScript and React questions.
