Round by round

1. 1

   Technical Round 160 min

   The first round combo of theory and coding, and it started with some React and frontend questions Frontend Theory:

   • The interviewer asked about useState vs useReducer, and I explained how useReducer is better for complex state management
   • I was asked about React.memo(), and we discussed when it’s useful for preventing unnecessary re-renders
   • They also asked about useCallback and useMemo, and I explained how each helps with performance optimization in React
   • Apart from React, there were some general data structure questions, including linked lists and dynamic programming, just to check my foundational knowledge Coding Questions: Kth Element of Two Sorted Arrays- binary search approach Drag-and-Drop List in React
   • Kth element of 2 sorted arrays
2. 2

   Technical Round 260 min

   Second round, mostly theory and a medium coding problem, and it started with some Redux and JavaScript questions Theory: Asked about actions, reducers, and the store in Redux, and i explained their roles and how state flows in a Redux application, they asked about thunks in Redux for async actions, which explained with example of fetching data from API and updating the store Coding: The coding problem was hard-level question, on arrays
