Interview preparation journey

Journey

I prepared for the Backend Developer role by consistently solving DSA problems on platforms like Code360 and revising core CS fundamentals such as DBMS, OS, CN, and OOPs. Alongside, I gained hands-on experience with backend technologies like Java, Spring Boot, Node.js, Express.js, MySQL, MongoDB, and Redis while building projects such as authentication systems and e-commerce backends. I revised HTTP request types, APIs, and caching strategies, which helped me understand real-world problem-solving. To strengthen my explanation skills, I practiced mock interviews and learned to explain both brute-force and optimized approaches clearly. This mix of coding practice, fundamentals, and project work shaped my backend preparation journey.

1. Triangle Pattern Printing

Given a positive integer n, print triangle-shaped patterns to the console (e.g., left-aligned, right-aligned, or centered) consisting of characters such as * or numbers. The pattern must have n rows and follow the specified alignment and character rules.

2. Palindrome Check

Given a non-empty string, determine whether it is a palindrome. A palindrome reads the same forward and backward. Return a boolean indicating if the string qualifies under the given constraints (e.g., case sensitivity, alphanumeric-only if specified).
