Journey
I am grateful to the Coding Ninjas mentors team for guiding me throughout my preparation journey. Their support was invaluable, especially during mock interviews, where I was able to identify the areas I was lagging in. Based on their feedback, I focused on practicing those weak points intensively.
I spent time revising key concepts, working on practical problems, and improving my coding and project skills. The combination of hands-on practice, mentor guidance, and repeated mock interviews helped me gain confidence and sharpen my problem-solving approach. As a result, I was well-prepared and successfully cleared the actual interview.
