Agile Interview Questions: If you are going for an interview, then it’s very common to face some of the Agile interview questions because nowadays most of the companies are following Israel methodologies to develop the software products.
So if you are started to worry about what are the Agile interview questions or discussions you have to face in the interview, then there is no need to worry. Because we have come off with some of the frequently asked interview questions, if you follow these interview questions, then it will help you to get an idea about the interview questions and also helps you to answer those questions.
Top Agile Interview Questions
Below we have mentioned some of the most asked Agile interview questions and answers.
When your requirements are frequently changing, then as a tester, what should be your approach?
If in your project you are following is agile methodologies, but the requirements are not precise and its changing frequently. then as a tester, you have to follow the below approach:
- you have to write the test cases or test plan in such a way that, will focus the requirement, not the exact details.
- To understand the requirement or scope of change, you have to work closely with the product owner or business analyst (BA).
What is the meaning of epic, user stories, end tasks?
If in an organization, you are following agile methodologies, then these terms are the basic terms that you came across in your daily life.
- Epic: A customer described software feature that is itemized in the product backlog is known as epic. Epics subdivided into stories.
- User Stories: As per the client requirement, the business analyst after the user stories. Which will define the project or functional business requirements, and it should be delivered in a particular sprint as expected.
- Task: what’s the user stories are groomed, then the developers and testers are broken down the user stories into different tasks.
What is refactoring?
Let’s assume that the development of an application is completed. But there is a requirement to improve the performance of the existing code. So to enhance the performance of the current code, we need to modify the code without changing the core functionality. This is called refactoring.
How can you calculate the velocity of the sprint with varying team capacity?
During the sprint planning, usually, the velocity of the sprint is measured based on the performance of the team on the completed sprints. Velocity is a metric that is calculated by the addition of all efforts estimates related to user stories completed in an iteration. It figures out how much work Agile can complete in a sprint and how much time will it need to finish a project.
but there is a mathematical formula which is used to calculate the velocity of a sprint:
- First – completed story points X team capacity: If you measure capacity as a percentage of a 40 hours weeks
- Second – completed story points/team capacity: If you measure capacity in manhours For our scenario, the second method is applicable.
- Product backlog: it contains all the features of the project, and the product owner owns it.
- Sprint backlog: It is a part of the product backlog which is owned by the development team and also committed to delivering within a sprint. This sprint backlog is prepared during the sprint planning meeting, and the user stories are groomed.
- Iterative model: It is a continuous software development method where the software development cycle is going on a repeated manner until the final product is achieved.
- Incremental model: in this model, the software is developed by portion-wise. in each increment, each segment of functionality is delivered through cross-discipline work from the requirements to the deployment.
What is the meaning of spike and zero sprints in agile? What is the purpose of it?
Sprint Zero: if you are going to start a new project, then before starting the development of the project, you need to do some research and POC on some of the features. Usually, on sprint zero, the developers are performing some activities like setting a development environment, preparing product backlog, and so on.
Spikes: Spikes are the type of stories that are used for activities like research, exploration, design, and even prototyping. In between sprints, you can take spikes for the work related to any technical or design issue. Spikes are of two types Technical Spikes and Functional Spikes.
What are the qualities of a good Agile tester should have?
An excellent Agile tester should have the following qualities.
- It should be able to understand the requirements quickly.
- An agile tester should know Agile principals and concepts thoroughly.
- As requirements keep changing, the tester should understand the risk involved in it.
- Based on the needs Agile tester should be able to prioritize the work.
- Continue communication between business associates, developers, and tester is a must.
Who are all involved in the Agile team?
In agile the two main leads are
- Scrum Masters: It coordinates most of the inputs and outputs required for an agile program
- Development Managers: They hire the right people and develop them with the team.
Difference between Scrum and Agile?
Scrum: In the scrum, a sprint is a basic unit of development. Each sprint followed by a planning meeting, where the tasks for the sprint identified and estimated. During each sprint, the team creates the finished portion of a product.
Agile: In Agile, each iteration involves a team working through a full software development cycle, including planning, design, coding, requirement analysis, unit testing, and acceptance testing when a product is demonstrated to stakeholders In simple words, Agile is the practice, and scrum is the process of following this practice.
What is test-driven development?
Test-driven development or TDD is also known as test-driven design. In this method, a developer first writes an automated test case which describes new function or improvement and then creates small codes to pass that test and later refactors the new code to meet the acceptable standards.
What is the burn-up and burndown chart in Agile methodology?
To track the progress of a project burn up and Bandhan chart are used
- Burnup Chart: It shows the development of stories done over time
- Burndown Chart: It shows how much work was left to do overtime
Scrum-ban is a software development model based on Scrum and Kanban. It is specially designed for a project that requires frequent maintenance, having unexpected user stories, and programming errors. Using this approach, the team’s workflow is guided in a way that allows minimum completion time for each user story or programming error.
What is the story point in agile?
The story point is to represent the difficulty of the story without assigning the actual hours. the story points are scaled like Fibonacci number sequence ( 1,2,3,5,8,13,….100). but some teams are using a linear scale (1,2,3,4….) Powers of 2 (1,2,4,8……) and cloth size (XS, S ,M,L, XL)
Why is continuous integration essential in Agile methodology?
continuous-integration is necessary because of the following reasons:
- It helps to maintain a release schedule on time by detecting bugs or integration errors
- Due to frequent agile code delivery usually every sprint of 2-3 weeks, stable quality of build is a must and continuous integration ensures that In helps to maintain the quality and bug-free state of the codebase
- Continuous integration helps to check the impact of work on branches to the main trunk if development work is going on branches using the automatic building and merging function
What testing are done by the tester during the agile?
In Agile, some activities are carried out. the developers are doing the elementary testing, which is unit testing and exploratory testing. Depending on the project requires a tester may execute functional and non-functional testing of the application.
