I applied via Naukri.com and was interviewed before May 2020. There were 3 interview rounds.
Functional elements tools are used to test the functionality of software applications.
Functional testing tools are used to test the behavior of software applications.
These tools verify that the software meets the functional requirements specified in the design.
Examples of functional testing tools include Selenium, HP QuickTest Professional, and IBM Rational Functional Tester.
I was interviewed in Nov 2020.

Started with the introduction.
Then there were two-three coding questions.
Some OS and DBMS concepts were asked.
Questions related to testing were also included.
You are given a string STR
which contains alphabets, numbers, and special characters. Your task is to reverse the string.
STR = "abcde"
"e...
Reverse a given string containing alphabets, numbers, and special characters.
Iterate through the characters of the string from end to start and append them to a new string.
Use built-in functions like reverse() or StringBuilder in languages like Python or Java for efficient reversal.
Handle special characters and numbers along with alphabets while reversing the string.
Ensure to consider the constraints on the number of t
You are provided with a positive integer N
. Your task is to identify all numbers such that the sum of the number and its digits equals N
.
N = 21
Identify numbers whose sum of digits and number equals given integer N.
Iterate through numbers from 1 to N and check if sum of number and its digits equals N.
Use a helper function to calculate sum of digits for a given number.
Return the numbers that satisfy the condition in increasing order, else return -1.

This was quite a tough round that can be cleared only by practice and understanding the problem. They asked about the profile first, then questions related to testing, SDLC, and so on. And then, I was asked to write test cases for two to three problems. Writing a test case was a task in this round. The interview was a senior testing engineer and was very friendly and helpful also and answered all my queries related to work.
Tip 1 : Practice question from every section (Arrays, String, Data Structures)
Tip 2 : Practice question that required you to write test cases for a problem (as they judge you on your practical implementation)
Tip 3 : Practice low level designing questions (it indirectly helps you to write test cases )
Tip 4 : Choose your favorite Data Structure and practice well on it (as this is the most commonly asked question)
Tip 1 : Have at least three projects in your resume (Include only those which you can explain and demonstrate)
Tip 2 : Include a column of "Position of Responsibility" in addition to your work experience and technicalities (it is impactful as it shows your extra activities apart from your regular curriculum)
I applied via Company Website and was interviewed in Feb 2022. There was 1 interview round.

There were 22 MCQ questions of aptitude and technical based while 3 questions were of coding type.
Tips: MCQ questions were not time consuming , so try to do that questions in less time , so you will get enough time for coding questions.
Given a string STR
consisting solely of the characters '{', '}', '(', ')', '[', and ']', determine whether the parentheses are balanced.
The first line contains an inte...
Implement a function to check if parentheses in a string are balanced.
Use a stack to keep track of opening parentheses and pop when a closing parenthesis is encountered.
If the stack is empty when a closing parenthesis is encountered or if there are unmatched parentheses at the end, return 'NO'.
Ensure that all opening parentheses have a corresponding closing parenthesis in the correct order.
Return 'YES' if all parenthes...
Given a string S
that represents a number, determine the smallest number that is strictly greater than the original number and has the same set of ...
The task is to find the smallest number greater than the given number with the same set of digits.
Sort the digits of the number in descending order.
Find the first digit from the right that is smaller than the digit to its right.
Swap this digit with the smallest digit to its right that is greater than it.
Sort all the digits to the right of the swapped digit in ascending order to get the smallest number greater than the

My experience was very awesome , I answered all the questions , although in starting I was very nervous , so at starting interviewer help me get my confidence, interviewer was very helpful.
Given an arbitrary binary tree consisting of N nodes, where each node is associated with a certain value, your task is to find the maximum sum for any le...
Find the maximum sum for any level in a binary tree.
Traverse the binary tree level by level and calculate the sum for each level.
Keep track of the maximum sum encountered so far.
Return the maximum sum found.
Example: For the input tree, the maximum level sum is 13 (5+6+2).
Given an integer array ARR
and an integer K
, your task is to find the K
most frequent elements in ARR
. Return the elements sorted in ascending order.
Find the K most frequent elements in an integer array and return them sorted in ascending order.
Use a hashmap to store the frequency of each element in the array.
Use a min heap to keep track of the K most frequent elements.
Return the elements from the min heap in ascending order.

This round was based on DSA and questions on core subjects that I had studied throughout college.
Given a binary tree where each node has a positive integer value, compute the vertical sum of the nodes. The vertical sum is defined as the sum of all nodes aligned along the...
Compute the vertical sum of nodes in a binary tree aligned along the same vertical line.
Traverse the binary tree in a level order manner to calculate the vertical sum.
Use a hashmap to store the vertical sum at each vertical level.
Recursively traverse the tree and update the vertical sum in the hashmap.
Output the vertical sums in the required format for each test case.
TCP/IP is a set of protocols that governs the way data is transmitted over the internet.
TCP/IP stands for Transmission Control Protocol/Internet Protocol.
It is a suite of communication protocols used to connect devices on the internet.
TCP ensures that data is reliably transmitted between devices.

In the interview I was asked few puzzles and few coding problems.
In the coding questions the interviewers did not ask me to write down the complete codes of the problems, they only asked me to suggest some suitable algorithms.

.
You should return the result modulo 109+7 as the co...

and ARR2
of size M and N, respectively, merge them into ARR1
as one sorted array. Assume that ARR1
has a size of M + N to hol...
