Top 50 Agile Interview Questions and Answers
1. What is Agile methodology, and how does it differ from traditional project management?
Agile methodology is an iterative and incremental approach to project management that emphasizes flexibility and adaptability. It differs from traditional project management in that it places a greater emphasis on collaboration, communication, and responding to change.
2. What do you mean by Pair Programming? Write its advantages.
Pair programming is a collaborative programming technique where two individuals work together to write code, sharing one computer or machine. It is commonly employed in Agile software development methodologies. During pair programming, one person writes the code while the other reviews each line and checks for errors. They also switch their roles intermittently to ensure both individuals are engaged and contributing equally.
Advantages of Pair Programming
- Develop higher-quality code
- Reduce the risk of errors
- An effective way to share knowledge
- Enhanced productivity
- Improved team collaboration
3. How do you handle changing requirements in Agile development?
In Agile development, changing requirements are expected, and the Agile process is designed to accommodate them. This is achieved through constant communication with the customer, continuous testing and feedback, and prioritizing the product backlog based on the customer’s needs.
4. What is the Agile Manifesto, and what principles does it embody?
The Agile Manifesto is a statement of values and principles for Agile software development. It embodies a focus on individuals and interactions, working software, customer collaboration, and responding to change. It emphasizes delivering working software frequently and involving customers and stakeholders in the development process.
5. What are the roles and responsibilities of the Scrum Master in Agile?
The Scrum Master is responsible for facilitating the Scrum process and ensuring that the team follows the Agile principles and practices. They also remove any impediments that may prevent the team from achieving their goals and work closely with the product owner to prioritize the product backlog.
6. What do you mean by the term “velocity” in Agile?
Velocity is a metric used in Agile software development to measure the amount of work a team can complete within a single sprint and estimate the time required to complete a project. It serves as a valuable tool for teams to calibrate their work capacity and create realistic timelines. Furthermore, velocity enables teams to identify potential bottlenecks and measure their progress and improvements over time.
7. What is a sprint, and how is it different from a release?
A sprint is a time-boxed period of development in Agile that typically lasts two to four weeks. It is used to complete a set of user stories or tasks from the product backlog. A release, on the other hand, is a deployment of a completed set of features to the end users.
8. What is the Agile process for estimating and planning projects?
The Agile process for estimating and planning projects involves breaking down the project into smaller user stories or tasks and estimating the effort required to complete each one. The team then prioritizes these items and plans the sprint backlog based on the highest priority items.
9. What is a user story in Agile, and how is it used?
A user story in Agile is a short description of a feature or functionality from the perspective of the end-user. It is used to define requirements and prioritize development efforts based on the value they deliver to the customer.
10. What are the main artifacts of the Scrum Framework?
There are three main artifacts of the Scrum Framework:
- Product Backlog: A product backlog is an organized list of all the work that needs to be done on the product. It includes requirements from clients or stakeholders that should be accomplished before the end of the project.
- Sprint Backlog: A sprint backlog is a list of all the work items selected by the scrum team for completion during the current sprint. It includes finalized user stories, bug fixes, and other work items that the team commits to completing during the sprint.
- Product Increment: A product increment is the updated version of the product that is derived from the completion of each sprint. It is the sum of all the completed and implemented user stories, features, and functionalities that have been developed and tested during the sprints.
11. How do you prioritize the product backlog in Agile development?
In Agile development, the product backlog is prioritized based on the value it delivers to the customer. This is achieved by working closely with the product owner and stakeholders to understand their needs and priorities and then ordering the backlog items accordingly.
12. What is the difference between a product backlog and a sprint backlog?
A product backlog is a prioritized list of features and functionalities that need to be developed over the course of the project, while a sprint backlog is a list of items from the product backlog that are selected for development during a sprint.
13. What is pair programming in Agile, and how is it beneficial?
Pair programming in Agile:
- A practice where two programmers work together on a single task or user story
- One person is the “driver” and writes the code while the other is the “navigator” and reviews the code as it is being written
- Benefits include increased code quality, knowledge sharing, reduced errors, and improved team collaboration and communication
14. What do you mean by refactoring?
Refactoring is the process of modifying the internal structure of software without altering its external behavior or functionality. It involves making changes to the code to enhance its internal structure, making it more readable, maintainable, and efficient. One popular refactoring technique used in Agile software development is Red-Green refactoring. Consistent refactoring habits improve code maintainability and ease of extension, ultimately resulting in a more robust and reliable software system
