Agile methodology is an iterative approach to software development that emphasizes flexibility, collaboration, and customer satisfaction.
Agile focuses on delivering working software in short iterations
It values individuals and interactions over processes and tools
It emphasizes responding to change over following a plan
Examples include Scrum, Kanban, and Extreme Programming (XP)
IP address is a unique identifier assigned to devices on a network. MAC address is a unique identifier assigned to network interface controllers.
IP address stands for Internet Protocol address and is used to identify devices on a network
MAC address stands for Media Access Control address and is used to identify network interface controllers
IP address is a 32-bit or 128-bit number, while MAC address is a 48-bit number

Smoke testing is a shallow and wide approach to check if the application is stable enough for further testing. Sanity testing is a narrow and deep approach to check if the specific functionality is working as expected.
Smoke testing is done to check the basic functionality of the application.
Sanity testing is done to check the specific functionality of the application.
Smoke testing is done after the build is received fr...
Pre-release testing includes functional, regression, integration, and acceptance testing.
Functional testing ensures that the software meets the specified requirements.
Regression testing ensures that changes made to the software do not affect existing functionality.
Integration testing verifies that different modules of the software work together seamlessly.
Acceptance testing is done by the end-users to ensure that the s
We perform functional, regression, integration, and acceptance testing in our project.
Functional testing to ensure the software meets the requirements
Regression testing to ensure new changes do not break existing functionality
Integration testing to ensure different modules work together
Acceptance testing to ensure the software meets the customer's expectations
Backlog in Agile is a prioritized list of features or tasks to be completed in a project.
Backlog is a living document that is constantly updated throughout the project.
It contains user stories, bugs, technical tasks, and other work items.
The items in the backlog are prioritized based on their business value and urgency.
The backlog is used to plan and track progress in Agile development.
Examples of Agile tools for manag
Various documents are created during testing to ensure proper planning, execution, and reporting of the testing process.
Test plan document
Test case document
Test execution report
Defect report
Traceability matrix
Test summary report
Amazon Web Services (AWS) is a cloud computing platform that provides a wide range of services for businesses and individuals.
AWS offers services such as computing, storage, databases, analytics, machine learning, and more.
It allows users to access these services on a pay-as-you-go basis, meaning they only pay for what they use.

Bug life cycle is the process of identifying, reporting, fixing, and verifying software defects.
Bug is identified by testers during testing
Bug is reported to the development team
Development team fixes the bug
Fixed bug is verified by testers
Bug is closed if it is fixed or rejected if it is not a bug

Round duration - 40 minutes
Round difficulty - Medium
Asked about time complexity of algorithm, puzzles, DBMS, cutting edge technologies etc. What are indexes?
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 duration - 20 minutes
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.

Hashmap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.
Hashmap uses a hashing function to map keys to indices in an array.
It allows for constant time complexity O(1) for insertion, deletion, and retrieval operations.
Example: HashMap<String, Integer> map = new HashMap<>(); map.put("key", 123); int value = map.get("key");
