We all get a bit nervous about Agile interview Questions, don’t we? No matter how capable you are or how knowledgeable you are or how much experience you have, interviews are about how you present yourself, and how well you manage to put your knowledge into suitably answering the questions.
Hence, it is always preferable to do a bit of research before attending an interview. Revise the answers and brush up on your skills.
Several Agile Methodology interview questions are generally asked in an interview. Here is the list of the top Agile interview questions and answers to help you prepare for the Agile process and Agile Methodology interviews.

Agile is a software framework of behaviors and approaches encouraging in-time production, which enables customers to receive quality software sooner.
Agile involves iterative project implementation approaches, whereas traditional methods include various project life cycle phases.
The difference between Agile and Scrum -Yes! Agile is a broad umbrella under which Scrum falls and consists of four primary values and twelve principles. Scrum has its own set of principles and values and provides a lighter framework to helps the team become agile.
There are several other frameworks in addition to Scrum, such as:
Usually, Waterfall is used when the requirements are simple, fully defined, predictable, and understood, and will not change.
The life of the Scrum cycle depends on the project size and team size. The team size may vary from 3 to 9 members. Usually, it takes 3 to 4 weeks to complete a Scrum sprint.
Suppose seven teams are working on a project and each team has seven members. Each team leads its particular scrum meeting. To coordinate among distinct teams, a separate meeting has to be organized, that meeting is called Scrum of Scrums.
An ambassador represents its team in the scrum of scrums.
Primary points discussed in the meeting are:

A software feature defined by a customer and itemized in the product backlog is known as epic. The subdivisions of Epics are known as stories.
User Stories: User stories are prepared according to the client's perspective such as project or business functions, and delivered in a particular sprint.
Task: Th user stories are further broken down into various task
Iterative method: It is a continuous software development process where the software development cycles (Sprint & Releases) are repeated until the final product is achieved.
Release 1: Sprint 1, 2… n
Release n: Sprint 1, 2 ...n
Incremental development: It segregates the functionality of the system into increments or portions. In each increment, the functionality segments are delivered through cross-discipline work, from the requirements to the deployment.
Test-driven development or TDD is also known as test-driven design. In this method, a developer writes an automated test case describing the new function and then create small codes to pass that test, and later re-factors the new code to meet the acceptable standards
The card-based estimation technique is based on a general agreement, which is known as scrum poker or planning poker. Some features of it are:-
There are some major points regarding agile testing and they are discussed below.
Some of the major disadvantages of the agile system are discussed below.
There are specific developments and methodologies that can use Agile like crystal methodologies, lean software development feature drove growth, and dynamic development.
stories that are approved.
To ensure that during the final development stage, there is no major problem left behind a code or version or a build is released, which is known as a release candidate. This is equivalent to the final build, and it is used for testing.
In major methodologies of agile testing cases, the code is divided into smaller parts. At one specific time, each branch of code is tested. Also, continuous communication is done on that part of the code. The agile process is more flexible and focused.
A zero sprint can be defined as the pre-step to the first sprint. Things such as setting up the environment to develop, prepare backlog, etc. that need to be performed before the start of the initial sprint and can treat it as Sprint zero.
The Scrum unit which is used to estimate the effort required to finish or implement a backlog is referred to as a story point in the scrum.
It is not mandatory to estimate user stories in terms of man hurt as it will mean a lack of product quality, which is to be delivered to the customer. In the case of the working hour, more attention is given to the budget and cost of management.
This is why the story point is necessary as it provides concepts regarding efforts, which are required, and also the complexity of the work.
The finest way to follow up action items is to establish a follow-up of the works to be done by the team members. And the scrum master will collect this information.
The following are the critical agile Matrices.
A professional Agile tester should have the following qualities
The various challenges involved in developing Agile Software includes
Before using Agile methodology, you must ask the following questions:
A product roadmap refers to the holistic view of product features, which creates the product vision.
It is the description in the form of a graph that shows implemented product backlog is called a burndown chart.
A graph is the representation of the no. of the implemented sprints and non-implemented sprints in the scrum cycle.
The graph is set to be a Release burndown chart when it is used to depict the pending release.
No. of defects identified and removed is represented by the defect burndown chart
The common metrics for Agile is as follows:
If capacity is measured as a percentage of 40 hours weeks then the work is done = story points * team capacity
In case the capacity is measured in terms of man-hours -> story points/team capacity.
The differences between Agile vs DevOps are:
|Usage||Developing Software||Deploying software|
|Developer tasks||Every person can handle all the tasks||Separate teams for operations and developments|
|Performance||Since every developer can progress the task, the agile approach is preferred||Teams need to communicate in order to proceed to the next step|
|Communication||Scrum-based approach to communicate||Regular meetings are held|
|Programming knowledge||Much needed as it includes development||Deployment needs less programming knowledge when compared to the development|
|Focus||Quality focussed software development||Improve deployment frequency|
Agile and Scrum certifications are hot in the market and organizations are expecting the candidates to hold one or more out of it. Agile Certifications and scrum certification are generally preferred by organizations are listed as follows:
The major agile quality strategies are:
Project management tools used in Agile are listed below:
Pair programming is a technique in which two programmers work as a team where. One programmer writes code and the other one reviews that code. They both can switch their roles.
Knowledge transfer is smooth: One experience partner can teach another partner about the codes and techniques.
Code quality: As the second partner simultaneously reviews the code, the chances of mistakes being occurred will reduce.
Modifying code without a change in its functionality to improve the performance is called refactoring.

QA provides additional value to the story thinking differently about distinct scenarios. It gives quick feedback to the developers on whether the new functionality is working fine or not.
Application Binary Interface defines an interface to compile application programs or the low-level interface between an application and the operating system.
Tracer bullet examines the working and examines the feasibility of an end-to-end process. It is the spike with the current set of practices or architecture.
The increment can be defined as the total of all backlog items of a product during a sprint. Being cumulative, each increment consists of its previous sprint increment values. It should set to be in the available mode in its subsequent release as it is a step to reach the goal.
Kanban is a tool that helps teams to keep an eye on the work for measuring its progress. Apart from the progress, the status of a development story can be seamlessly described with the help of the 'kanban board'.
In the case of outsourced resources, using remote project management tools will help you meet the required remote team management. It helps you know how to get them on board, and manage people, tools, and resources.
It is the meeting conducted in the last part of the sprint after the review meeting of a sprint. The whole team will participate in this discussion, which lasts for 2 to 3 hours.
The file testing methodologies of Agile can be applied in the case of biomedical, biophysics, biochemistry, and those places which are having insufficient data and the project needs to complete with a small team.
Any obstacles that do not allow a smooth flow of work, which results in the underperformance of the team to perform tasks in a better way is known as an impediment.
The meeting that involves the entire scrum team from product owner to scrum master and other team members is known as a sprint planning meeting. It is arranged to discuss the important feature of the team and also the items of the product backlog.
When shifting to the prominent and appropriate process is required, then you use Scrum. When the need is to improve the process that is running provided with lesser changes, then Kanban is used.
Understanding the purpose and expectations, as well as sharing knowledge, are the primary qualities of a Scrum Master.
The primary tools used in a Scrum project are:
Only the Product Owner can cancel the Sprint. It can be canceled before the Sprint timebox limit ends.
When the sprint is finished by the team it is usually meant that all the tasks that they have planned have been completed. The term increment refers to the sum of all the backlog product items that were completed in a sprint. The new increment value will have the value of the last sprint value.
The technique which is a card-based estimation based on a general agreement is known as scrum poker or planning poker. Some features of it are:-
There are certain methodologies and developments which can use agile like lean software development feature drove development, dynamic development, and crystal methodologies.
In the case of agile testing methodology, the code that is used is broken into smaller branches. At one particular time, each particular branch of code is tested. Also, continuous communication is done on that part of the code. The agile process is more flexible and focused.
The methodology of file testing can be applied in the case of biophysics, biochemistry, biomedical, and those places that have insufficient data and the project needs to complete with a small team.
You will know that you are using agile development is when you are using a time-boxed task board, test-driven development, daily stand-up meetings, pair programming, and many more.
In the burndown chart, the X-axis represents the working days and the Y-axis stands for showing the remaining efforts.
There are certain times when the developer accidentally commits a bug in the software. This bug might stop the process of compilation or generated warring. It is the cause of failure during the normal execution of testing. In such cases, it is said that the build is broken. The main priority of the tester now is to rectify the bug.
When there is a need for shifting towards an appropriate and prominent process then you use Scrum. When you need to improve the process that is running provided that there are not many changes then Kanban is used.
The scrum master can remove impediments on behalf of the scrum team but he should not do that. The scrum master should not pamper nor overrule the scrum team. Also, the scrum team should be able to make their own decisions.
There are various places where agile methodology can be applied in the field of biophysics, biochemistry, biomedical, or at the place where there is insufficient data, where the project needs to be completed in a small team, where to work in unknown and there are several areas.
The major Agile components include:
The best way to do this is by establishing a follow-up of the works that are to be done by the members of the team. The information is to be collected by the scrum master.
