Smoke testing is a preliminary testing to check if the software build is stable enough for further testing.
Smoke testing is a type of non-exhaustive testing
It is performed to ensure that the critical functionalities of the software are working fine
It is usually done after a new build is received
It helps in identifying the major issues early in the testing cycle
Example: Checking if the login page is working fine after a
Regression testing is testing the entire system after changes while retesting is testing only the failed test cases.
Regression testing is done to ensure that changes made to the system do not affect the existing functionality.
Retesting is done to ensure that the defects found in the previous test cycle have been fixed.
Regression testing is done after every build while retesting is done after every defect fix.

In this round, there were 4 sections of MCQs, along with two coding questions. It lasted for 2.5 hours in which the camera was on along with the microphone on the platform AMCAT. One coding question was of hard difficulty level of graph and another was of medium level difficulty question of dynamic programming. MCQ part was quite easy with a timer, on each sub part and can be easily solved.
Given a connected, undirected, and acyclic graph where some nodes are marked and a positive integer 'K'. Your task is to return the count of nodes such that...
Count nodes within K-distance from marked nodes in a connected, undirected, acyclic graph.
Create an adjacency list to represent the graph.
Use BFS to traverse the graph and calculate distances from marked nodes.
Keep track of visited nodes and distances to avoid revisiting nodes.
Return the count of nodes with distances less than 'K' from all marked nodes.
Handle edge cases like empty graph or marked nodes.
Given an infinite supply of coins of each denomination from a list, determine the total number of distinct ways to make a change for a specified value. If making the change isn't ...
Given coin denominations and a target value, find the total number of ways to make change.
Use dynamic programming to keep track of the number of ways to make change for each value up to the target value.
Iterate through each denomination and update the number of ways to make change for each value.
Handle base cases such as making change for 0 value.
Consider all possible combinations of denominations to make change for th

Interviewer was straight forward, and direct in approach, and did not waste even a single second of his or mine. Sharp after 30 minutes the interview was ended.
through out the interview, he was friendly, and just observing.
Firstly, 3 coding questions, were asked, then 2 concepts of java and 1 concept of data structures was asked.
the question related to java were, demon thread and platform independence. In data structures, I was asked to give brief intro regarding the AVL trees.
Given a sorted array or list of integers with size N and an integer X, you need to determine how many times X appears in the array/list.
The first line of t...
Count occurrences of a given integer in a sorted array.
Use binary search to find the first and last occurrence of X in the array.
Calculate the count by subtracting the indices of the last and first occurrences.
Handle cases where X is not present in the array.
Given a sequence of numbers, denoted as ARR
, your task is to return a sorted sequence of ARR
in non-descending order using the Merge Sort algorithm.
The Merge Sort...
Implement Merge Sort algorithm to sort a sequence of numbers in non-descending order.
Divide the input array into two halves recursively until each part has a size of '1'.
Merge the sorted arrays to return one fully sorted array.
Time complexity of Merge Sort is O(n log n).
Your task is to implement a Stack data structure using a Singly Linked List.
Create a class named Stack
which supports the following operations, each in O(1...
Implement a Stack data structure using a Singly Linked List with operations in O(1) time.
Create a class named Stack with getSize, isEmpty, push, pop, and getTop methods.
Use a Singly Linked List to store the elements of the stack.
Ensure each operation runs in O(1) time complexity.
Handle edge cases like empty stack appropriately.
Example: For input '5 3 10 5 1 2 4', the output should be '10 1 false'.

Before the interview in the morning, we were given the topics on which we had to write 100 words.
Tip 1 : Solve all the question with Microsoft, Amazon tags on geeksforgeeks.
Tip 2 : Never give up during the interview, rather just keep trying whether you reach the solution or not.
Tip 3 : Be confident, this is the most important requirement.
Tip 1 : Claim the things, that you have done in actual by your own.

It basically consisted of a 2hr test(approx) on AMCAT. The test consisted of 2 coding question and 20 questions of quantitative, reasoning and technical question based on DBMS, DS and small C coding.
You are given an array ARR
of long type, which represents an elevation map where ARR[i]
denotes the elevation of the ith
bar. Calculate the total amount of rainwater t...
Calculate the total amount of rainwater that can be trapped within given elevation map.
Iterate through the array to find the maximum height on the left and right of each bar.
Calculate the amount of water that can be trapped above each bar by taking the minimum of the maximum heights on the left and right.
Sum up the trapped water above each bar to get the total trapped water for the elevation map.

The 2nd Round was technical interview round.
It started with the usual “Tell me something about yourself”. Then he asked questions based on resume, like I had mentioned that I am familiar with Concepts of Data Science and Machine, so he asked a few questions on them. Then he asked about OOPS concepts and he also asked few questions on my project.
