I applied via Campus Placement and was interviewed in Aug 2022. There were 3 interview rounds.
Technical MCQ and coding (medium)
This was long programing round. In this you need to design a application. First you need do ER or class diagram. Then you need code in any programing language but OOPS is prefered. They see is app is scalable and data modeling
(4 Questions)
- Q1. Basing OOPS, DBMS, SQL and DS
- Q2. Sql joins and normalisation
- Q3. Sort stack ds and real life example
- Ans.
Sorting a stack data structure and its real-life example
Sorting a stack involves popping elements and comparing them to the remaining elements in the stack
Real-life example: arranging books on a shelf in alphabetical order
Another example: sorting a deck of cards by suit and rank
- Q4. Question from resume and previous round solution

Round duration - 90 minutes
Round difficulty - Medium
The round consisted of 3 coding Questions and 20 Technical MCQs.
- Q1.
Connect Ropes Problem Statement
Given a number of ropes denoted as 'N' and an array containing the lengths of these ropes, your task is to connect the ropes into one single rope. The cost to connect two r...
- Ans.
The task is to find the minimum cost required to connect all the ropes by summing their lengths.
Iterate through the ropes and connect the two shortest ropes at each step to minimize cost
Use a priority queue to efficiently find the shortest ropes
Keep track of the total cost as you connect the ropes
Example: For input [4, 3, 2, 6], connect 2 and 3 (cost 5), then connect 4 and 5 (cost 9), then connect 9 and 6 (cost 15) for
- Q2.
Idempotent Matrix Verification
Determine if a given N * N matrix is an idempotent matrix. A matrix is considered idempotent if it satisfies the following condition:
M * M = MInput:
The first line cont...
- Ans.
Check if a given matrix is idempotent by verifying if M * M = M.
Iterate through the matrix and multiply it with itself to check if it equals the original matrix.
If the condition M * M = M is satisfied, then the matrix is idempotent.
If the condition is not satisfied, then the matrix is not idempotent.
- Q3.
Sum of LCM Problem Statement
Given an integer 'N', calculate and print the sum of the least common multiples (LCM) for each integer from 1 to N with N.
The sum is represented as:
LCM(1, N) + LCM(2, N) + .... - Ans.
Calculate and print the sum of least common multiples (LCM) for each integer from 1 to N with N.
Iterate from 1 to N and calculate LCM of each number with N
Add all the calculated LCM values to get the final sum
Return the sum for each test case
Round duration - 120 minutes
Round difficulty - Medium
This round is a Long Coding Round. Every Candidate was assigned with a mentor who guides them, We were given a real-life scenario for which we have to construct a database with required tables. We should draw an ER Diagram to demonstrate the Database. After the Database Completion, We have to Start Coding the Application. The Design(like Placing the button or background colour) is not given much importance. They mainly test the practical knowledge of candidates in OOPS and expertise in a C, C++, Java, Android or any other language were OOPS Concepts can be applied.

This Round is a technical Interview. I was asked Questions to test my Technical Knowledge.
- Q1.
Sort 0 1 2 Problem Statement
Given an integer array
arrof size 'N' containing only 0s, 1s, and 2s, write an algorithm to sort the array.Input:
The first line contains an integer 'T' representing the n... - Ans.
Sort an array of 0s, 1s, and 2s in linear time complexity.
Use three pointers to keep track of 0s, 1s, and 2s while iterating through the array.
Swap elements based on the values encountered to sort the array in-place.
Time complexity of the algorithm should be O(N) where N is the size of the array.
Round duration - 20 Minutes
Round difficulty - Easy

Interview Questionnaire
8 Questions
- Q1. Find a number which occurs odd number of times and all number occurs even number of times
- Ans.
Find an odd occurring number among even occurring numbers.
Use XOR operation to cancel out even occurring numbers and get the odd occurring number.
Iterate through the array and XOR each element with the result variable.
The final result will be the odd occurring number.
- Q2. Some discussion about my minor project
- Q3. Spiral order of binary tree and mattrix, print it
- Ans.
Print the spiral order of a binary tree and matrix.
For binary tree, use level order traversal and alternate direction for each level.
For matrix, use four pointers to traverse in spiral order.
Example for binary tree: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8 -> 9
Example for matrix: 1 2 3 4 -> 8 7 6 5 -> 9 10 11 12 -> 16 15 14 13
- Q4. Some question about os,dbms
- Q5. Find pair which have a given sum in a given array
- Ans.
Finding pairs in an array with a given sum.
Iterate through the array and for each element, check if the difference between the given sum and the element exists in the array.
Use a hash table to store the elements of the array and their indices for faster lookup.
If there are multiple pairs with the same sum, return any one of them.
If no pair is found, return null or an empty array.
- Q6. Find total number of k element which have a given avg in a given array in minimum time complexity
- Ans.
Find total number of k element with given avg in an array in minimum time complexity.
Use sliding window technique to traverse the array in O(n) time complexity.
Maintain a sum variable to keep track of the sum of elements in the window.
If the sum of elements in the window is equal to k times the given avg, increment the count.
Move the window by subtracting the first element and adding the next element in the array.
- Q7. Print all elements which in not boundary element in a given binary tree
- Ans.
Printing non-boundary elements of a binary tree
Traverse the tree in any order (preorder, inorder, postorder)
Check if the current node is not a boundary node (not the first or last node in its level)
If it is not a boundary node, print its value
Recursively traverse its left and right subtrees
- Q8. Then some question about process synchronisation,error vs exception,and then 2-3 hr question
