Agile Interview Questions: Agile Methodology is a set of methods & practices where project management & software development takes place in delivering customer-centric items in a short-development cycle known as sprints. It’s an iterative method, and every iteration is specifically made to be small & manageable. Thus, this can be carried in a precise given time. Additionally, Agile are open to varying requirements in a period & encourages continuous feedback from the end-users.
With this agile interview questions article, you will have an idea of what to encounter thus, preparing you mentally. The major purpose of an interview is how well one presents themselves and the way they provide the knowledge to answering questions more suitably.
Top 30+ Agile Interview Questions
What’s Agile Testing?
This is a practice centred on principles of agile software development. Moreover, it includes every member of an agile team with some specific skills & certain expertise, which ensures timely product delivery with the release of extra features at repeated intervals.
Which are the various kinds of Agile Methodology?
Different kind of Agile frameworks or methods widely utilized in the world for the development of software & project includes:
- Feature-Driven Development (FDD) This generally involves making software models every two weeks & also requires development & design for every model feature. This is a lightweight incremental & iterative software development method whose main purpose is to provide stable and operating program on time.
- Scrum: This is used in establishing hypotheses, reflect on the experience, test them, & make adjustments. This heavily relies on feedback, small teams, self-management & work broken out into sprints. This relies on incremental development.
- Lean-Software Development: This is basically a method of reducing waste & maximizing value. It’s more focused to process productivity for best results in customer value. It’s totally dependent on 2 guiding principles, which is continuous improvement and respect for people.
- Crystal Methodology: This majorly focuses on people & their relations instead of processes. This is considered to be among the most lightweight & flexible approaches in developing software. It’s a family of agile methodologies which include various variants like crystal clear, crystal orange, crystal yellow & crystal red.
- Dynamic Software-Development Method (DSDM): This generally deals with a complete project lifecycle & the major aim is to guarantee the best governance as a foundation for project management. It’s user-driven & believes modifications to the project are constantly expected. This also offers a complete roadmap to convey products on time & within budget.
- Extreme Programming (XP): The major purpose is to yield higher-quality software & higher life quality for the development team. It’s considered to be a low-risk, flexible & a method to develop software & ensures clients gets the thing they need. With this Methodology, the software is verified right from the first day and collecting feedback which improves the development process.
- Adaptive-System Development (ASD): This represents the idea which projects need always to be in a state-of-continuous adaptation & has a cycle of 3 repeating series that includes speculating, learn and collaborate.
- Kanban: These projects are normally managed via a table or board. Kanban board tool helps the team members in keeping an eye on workflow for determining its progress & includes every information that’s required to be done on a product at every stage along with the path of completion. The major purpose is flexibility in task management, improved workflow and continuous improvement.
How is Agile-Methodology different from Traditional-Waterfall process?
Agile Methodology, software features are conveyed frequently. Thus testing activity is made simultaneously with development activity. Testing-time is reduced as just small features are required to be tested one time.
With the waterfall model, testing the activities takes place after the whole development process. In this case, testing time is long as the whole product is tested in a single move. Additionally, waterfall-methodology is closed-process where every stakeholder aren’t involved in the development process, and agile Methodology needs the participation of different stakeholders comprising customers.
Explain what increment is?
This is the total of every product backlogs-items that’s completed through a sprint. Every increment includes every previous sprint-increment value because it’s cumulative. This needs to be in available mode in a subsequent release because it’s a step in reaching your goal.

This is a metric which is calculated through the addition of every effort that estimates linked with clients stories finished in an-iteration. This predicts the amount of work Agile is capable of completing in a sprint & the amount of time it needs to complete the project.
This is the modification of code minus changing the functionality on how to improve performance.
What’s test stub?
This is a small code which mimics a particular component in system & can substitute it. It has the same output as the section it replaces.
What’s Test-Driven Development?
This is a test-first development method where we add test 1st before writing the full production code. Afterward, we run a test &, based on the result, refactor a code for fulfilling the test requirement.
There might be some mechanical issues or design-problem in a project which requires to be fixed first. To offer the solution to the issue, “Spikes” are made.
What is a tracer bullet?
This is a spike with current architecture or the current-set for best practices. Main purpose of tracer bullet is to examine the way an end-to-end process works & examines feasibility.
What are the various functions in Scrum?
- Product Owner: Here, the product-owner is the one that runs the product from a business perspective. He/she defines the necessities & prioritizes the values.
- Scrum Master: Here Scrum-Master is a team-leader & facility giver who assists the team member in following agile practices for them to meet their customer’s requirements and commitments
- Agile-Development Team: Here the team offers judgment to technical feasibilities or dependencies.
What’s the difference between product backlog & sprint backlog?
- Sprint backlog: This is a subset of product backlog possessed by the development team & commits to convey it in sprint. It’s made in Sprint-Planning Meeting
- Product backlog: This contains a full list of every desired characteristic & is owned by the product owner.
What’s Application Binary-Interface?
Across various system platforms & environments, a requirement stated by a specification for portability of uses in binary-form is recognized as Application-Binary Interface.
Importance of Continuous Integration in Agile?
- Helps in maintaining release-schedule on time via integration errors or detecting-bugs
- It helps to maintain the quality and bug-free state of code-base
- Frequent agile-code delivery every sprint of two to three weeks of stable quality of make is a must & continuous integration guarantees that
