Experience:

This comprehensive interview process for a Frontend Lead Engineer role at DealShare consisted of three rounds, and the candidate was selected. The overall difficulty was medium to high.

Round 1: Data Structures & Algorithms
This round tested fundamental DSA concepts. A specific question involved "Merging Two Sorted Arrays", where the efficient solution involved a two-pointer technique to achieve O(n + m) time complexity.

Round 2: Technical Discussion & Problem-Solving
This round likely involved discussions around technical challenges, system design, and architectural choices, focusing on problem-solving skills relevant to frontend development.

Round 3: Practical Implementation
The final round involved a practical coding task. The candidate was asked to create a stopwatch with start, stop, and reset functionalities using React state and hooks (useState, useEffect). Key requirements included accurate time tracking with setInterval and proper cleanup to avoid memory leaks.

Key takeaways and tips from this experience include strengthening DSA concepts (especially searching, sorting, and array manipulation), understanding performance optimizations for frontend applications, mastering React concepts (hooks, state management, lifecycle methods), and writing clean and efficient code.
