• Focus on building a strong foundation in React hooks, component lifecycle, and state management
• Time management is crucial—allocate time wisely between understanding the problem and implementing the solution

Round 2: Problem-Solving and Data Structures (PSDS) Round

This round evaluated the candidate's algorithmic thinking and proficiency in fundamental data structures. Questions in this stage typically cover arrays, strings, linked lists, trees, graphs, and dynamic programming problems.

Preparation Tips:

• Practice medium to hard-level problems on platforms like LeetCode and HackerRank
• Focus on time and space complexity analysis
• Be prepared to explain your approach and optimize solutions

Round 3: Domain/Machine Coding Round

The domain round focused on frontend-specific skills, requiring candidates to implement real-world UI components or features. This hands-on coding session assessed practical knowledge of React, TypeScript, and modern frontend practices.
