I applied via Campus Placement and was interviewed in Jul 2022. There were 3 interview rounds.
10 core subject MCQs along with 3 coding questions
1 Fizz Buzz questions
2 third largest string in array of strings
3 operation on numbers given by strings
Top view of binary tree is the nodes visible when viewed from the topmost node.
Top view shows the nodes visible from the root node's perspective.
Nodes are printed in the order of their horizontal distance from the root node.
If two nodes have the same horizontal distance, the node that appears first in the level order traversal is printed first.

Given an array of integers ARR
of size N, consisting of 0s and 1s, you need to select a sub-array and flip its bits. Your task is to return the maximum count of 1s that can b...
Given an array of 0s and 1s, find the maximum count of 1s by flipping a sub-array at most once.
Iterate through the array and keep track of the maximum count of 1s obtained by flipping a sub-array.
Consider flipping a sub-array from index i to j and calculate the count of 1s in the resulting array.
Return the maximum count of 1s obtained by flipping a sub-array at most once.

Round difficulty - Medium
Asked 1 standard algorithm
You are provided with a 2-dimensional matrix having N
rows and M
columns, containing only 1s (land) and 0s (water). Your goal is to determine the number of islands in t...
Count the number of islands in a 2D matrix of 1s and 0s.
Iterate through the matrix and perform depth-first search (DFS) to find connected 1s.
Mark visited cells to avoid redundant traversal.
Increment island count whenever a new island is encountered.
Tip 1 : prepare for competitive programming
Tip 2 : know about standard algorithm
Tip 3 : must be good with dbms
Tip 1 : must have projects, which you can explain to them
Tip 2 : have things on resume, that you are totally certain about.
