SDLC stands for Software Development Life Cycle.
It is a process followed by software development teams to design, develop, test and deploy software.
It includes phases like planning, analysis, design, implementation, testing, and maintenance.
It helps in delivering high-quality software that meets customer requirements and is completed within the budget and timeline.
Different models of SDLC include Waterfall, Agile, Spir...
Agile module is a part of the Agile methodology that focuses on a specific aspect of the project development process.
Agile modules are designed to be flexible and adaptable to changing project requirements.
Each module is typically focused on a specific feature or functionality of the project.
Modules are developed and tested in short iterations, allowing for quick feedback and adjustments.
The use of agile modules can he...
Smoke testing is a preliminary testing technique to check if the software build is stable enough for further testing.
It is a quick and shallow testing technique
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 major issues early in the testing cycle
It is not a substitute for comprehensive testing
Sleep testing is a type of testing that evaluates the performance of a system or application under low or no activity conditions.
It is used to identify any issues that may arise when a system or application is idle for an extended period of time.
It can also be used to test the performance of a system or application during low-traffic periods, such as overnight or during weekends.
Examples of sleep testing include testin...

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.
