—————————————————————————————————————————————-What is the duration of a scrum sprint?
Answer: Generally, the duration of a scrum sprint (scrum cycle) depends upon the size of project and team working on it. The team size may vary from 3-9 members. In general, a scrum script complete in 3-4 weeks.

Thus, on an average, the duration of a scrum sprint (scrum cycle) is 4 weeks. This type of sprint-based Agile scrum interview questions is very common in an agile or scrum master interview.

—————————————————————————————————————————————-What is the use of burn-up and burn-down charts?
Answer: The burn-up chart illustrates the amount of completed work in a project whereas the burn-down chart depicts the amount of work remained to complete a project. Thus, the burn-up and burn-down charts are used to trace the progress of a project.

—————————————————————————————————————————————-What is Velocity?
Answer: Velocity question is generally posed to understand if you have done some real work and familiar with the term. Its definition “Velocity is the rate at which team progresses print by sprint” should be enough. You can also add saying the important feature of velocity that it can’t be compared to two different scrum teams.

—————————————————————————————————————————————-What do you know about impediments in Scrum? Give some examples of impediments.
Answer: Impediments are the obstacles or issues faced by scrum team which slow down their speed of work. If something is trying to block the scrum team from their getting work “Done” then it is an impediment. Impediments can come in any form. Some of the impediments are given as –

Resource missing or sick team member
Technical, operational, organizational problems
Lack of management supportive system
Business problems
External issues such as weather, war etc
Lack of skill or knowledge
While answering impediments related agile scrum interview questions remember that you may be asked the way to remove any of the mentioned impediment.

—————————————————————————————————————————————-What is the increment? Explain.
PMI ACP Free Test

Answer: This is one of the commonly asked agile scrum interview questions and a quick answer can be given this way. An increment is the total of all the product backlogs items completed during a sprint.

Each increment includes all the previous sprint increment values as it is cumulative. It must be in the available mode in the subsequent release as it is a step to reach your goal.

—————————————————————————————————————————————-Do you know about Agile Manifesto & its Principles? Explain in brief.
Answer: This is the theory which most of agile/scrum roles aspirant should be on tips. Four manifesto values and 12 principles should be explained as much as possible as part of this question. Even if it’s not explained in 100% accurate manner it should be fine but intentions of values and principles should come out e.g.

Working Software should be demonstrated at regular intervals
Individuals & interaction – self-organization, self-motivating should be encouraged
Customer collaboration
Welcoming change at any point in time in the project

—————————————————————————————————————————————-List out the pros and cons of exploratory testing (used in Agile) and scripted testing?
Pros Cons
Exploratory Testing
– It requires less preparation- Easy to modify when requirement changes

– Works well when documentation is scarce
– Presenting progress and Coverage to project management is difficult Scripted Testing

– In case testing against legal or regulatory requirements it is very useful

– Test preparation is usually time-consuming- Same steps are tested over and again

– When requirement changes it is difficult to modify

————————————————————————————————————————-

Explain the difference between Extreme programming and Scrum? Scrum Extreme Programing (XP)
– Scrum teams usually have to work in iterations called sprints which usually last up to two weeks to one month long
– XP team works in iteration that last for one or two weeks – Scrum teams do not allow change into their sprints – XP teams are more flexible and change their iterations

—————————————————————————————————————————————-Do you have a Scrum Master certification?
This question may seem awkward to you but it is one of the most popular Agile Scrum interview questions. If an interviewer asks this question, it doesn’t mean that a certification is must for the job position. Just be confident while answering whether you have a scrum master certification or not.

If you are a certified scrum master, just share the details of your certification like certification exam, score obtained, and the year of passing the certification exam. In case you don’t have a certification, mention and highlight your experience in the particular field. Also, let the interviewer know if you are planning to invest in the certification in the near future.

Here’s the complete preparation guide for: PSM I Certification | PSM II Certification | PSM III Certification

—————————————————————————————————————————————-Mention what are the advantages of maintaining consistent iteration length throughout the project?
The advantages are
• It helps team to objectively measure progress
• It provides a consistent means of measuring team velocity
• It helps to establish a consistent pattern of delivery

—————————————————————————————————————————————-If a timebox plan needs to be reprioritized who should re-prioritise it?
If a timebox plan needs to be reprioritized it should include whole team, product owner, and developers.

—————————————————————————————————————————————-What is the difference and similarity between Agile and Scrum?
Answer: Difference between Agile and Scrum – Agile scrum is a broad spectrum, it is a methodology used for project management while Scrum is just a form of the Agile that describes the process and its steps more concisely.

Agile is a practice whereas scrum is a procedure to pursue this practice.

The similarity between Agile and Scrum – The Agile scrum involves completing projects in steps or incrementally. The Agile methodology is considered to be iterative in nature. Being a form of Agile, Scrum is same as that of the Agile. It is also incremental and iterative.

—————————————————————————————————————————————-What is the role of the Scrum Master?
Answer: Here’s how you can answer Scrum Master interview questions like this –

The scrum master is the leader as well as coach of the Scrum team. The scrum master is responsible to serve and protect his team from any kind of distractions that could affect their performance. The main role of the scrum master is to motivate his team to achieve the sprint goal.

He is focused to build a self-organized and motivated team where each member is familiar with the implementation of Agile and Scrum principles and applications. The scrum master keeps a proper check on the scrum team if they are executing committed tasks properly. He is also responsible to increase the efficiency and productivity of the team so that they can achieve the sprint goal effectively.

—————————————————————————————————————————————-What do you know about a story point in Scrum?
Answer: A story point in Scrum is the unit for the estimation of total efforts that are required to perform or complete a particular task. So, here is how you can answer such agile scrum interview questions on a single line.

—————————————————————————————————————————————-What is the role of Sashimi in Scrum methodology?
Answer: Sashimi plays an important role in Scrum methodology. Sashimi is a technique used by Scrum to check the completion of all the functions created by the developers.

Using this technique, all the requirements such as analysis, designing, coding, testing and documentation that are used in the constitution of a product are checked and only after that the product is displayed.

—————————————————————————————————————————————-What are the different roles in Scrum?
The three scrum roles i.e. Scrum Master, Product Owner and Team should be explained with the details of few primary responsibilities of each role. You can add more details as mentioned below for a particular depending on the role you are getting interviewed for.

Product owner – A product owner is actually the stakeholder of the project. He represents the project requirements before the team. He is responsible to have a vision of what to build and convey his detailed vision to the team. He is the starting point of an agile scrum interview and agile scrum software development project.

Scrum team – Scrum team is formed by the collective contribution of individuals who perform for the accomplishment of a particular project. The team is bound to work for the timely delivery of the requested product.

Scrum master – Scrum master is the leader and the coach for the scrum team who checks whether the scrum team is executing committed tasks properly. He is also responsible to increase the efficiency and productivity of the team so that they can achieve the sprint goal effectively.

—————————————————————————————————————————————-In Agile mention what is the difference between the Incremental and Iterative development?
Iterative: Iterative method is a continuous process of software development where the software development cycles are repeated (Sprint & Releases) till the final product is achieved. Release 1: Sprint 1, 2… n Release n: Sprint 1, 2….n

Incremental: Incremental development segregates the system functionality into increments or portions.
In each increment, each segment of functionality is delivered through cross-discipline work, from the requirements to the deployment.

———————————————————————————————————-

Explain what is Spike and Zero sprint in Agile?

What is the purpose of it? Sprint Zero: It is introduced to perform some research before initiating the first sprint. Usually this sprint is used during the start of the project for activities like setting development environment, preparing product backlog and so on.

Spikes:

Spikes are 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 responsibilities of a Scrum Master?
Answer: Key responsibilities of a Scrum Master involves:

Tracking and monitoring
Understanding requirements properly
Work to reach the project goal
Process checking master and quality master
Protect the team from detachments
Improving the performance of the team
Lead the meetings and resolve issues
Resolution of conflicts and impediments
Communication and reporting

—————————————————————————————————————————————-What are different ceremonies and their importance in Scrum?
Scrum planning, Scrum – Daily stand up, Scrum review & scrum retrospective ceremonies should be clearly expressed with the purpose of the ceremony. It’s important to remember the time-boxing of the ceremonies for a standard 4 weeks of Sprint or as per the Sprint you have used in your projects.

Agile Testing Interview Questions
Agile testing is the software development practice using practices of agile software development. In an interview for the Agile job, you may be asked agile testing questions, so have a look at the agile testing interview questions.

—————————————————————————————————————————————-What do you understand by the term Agile testing?
Answer: Agile testing is a software testing practice that is fully based on the agile principles of software development. It is an iterative methodology where the requirements are the outcome of collaboration between the product owner and team.

The agile principles and applications are applied to meet the customer requirements by successful completion of the project.

—————————————————————————————————————————————-What are the skills of a good Agile Tester?

Successful Scrum Master

Advanced Agile Scrum Interview Questions

The agile scrum is a vast field, so the interviewers seek candidates with advanced knowledge. Thus, the basic knowledge is not sufficient to crack the job interview. So, here we bring some frequently asked advanced agile scrum interview questions.

—————————————————————————————————————————————-What do you understand by the term “Scrum of Scrums”?
Answer: This is one of the commonly asked scrum master interview questions. Consider a case to understand the meaning of the term scrum of the scrums.

Let us assume an active project on which seven teams are currently working. The number of members of each team is also seven.

Each team is responsible to lead its own scrum meeting. But, in order to coordinate and communicate with different teams, it is required to organize a separate scrum meeting. The scrum meeting organized to hold a coordination between scrum teams is known as the scrum of scrums.

There is one team leader from every team, known as ambassador, who is responsible to represent his team in the scrum of scrums.

Scrum is an Agile framework, right? Name a few other Agile frameworks.
Answer: Yes, Scrum is an Agile framework. Few other Agile frameworks are –

Feature Driven Development
Test Driven Development
Kanban
While answering this type of Agile Scrum interview questions please note that name the frameworks you are familiar with or have followed.

—————————————————————————————————————————————-Explain some common metrics for Agile.
Answer: You may definitely come across agile scrum interview questions regarding agile scrum metrics. The question may be related to a particular agile matric or explaining all the metrics. So, the detailed description of some common metrics for Agile is as follows:

Velocity – Velocity is the average number of points from last 3-4 sprints. It is measured by the summation of the all approved estimates of the stories. It gives an idea of the capacity, progress etc.

Cumulative Flow Diagram – With the help of a cumulative flow diagram, an inspection is done over the uniform workflow. In this diagram/graph, the x-axis represents time whereas the y-axis represents the number of efforts.

Work Category Allocation – Work category allocation is an important factor that gives a quick information of the time investment i.e. where the time is being invested and which task should be given priority as a factor of time.

Time Coverage – It is the time that is given to a code during testing. It is calculated in percentage as a factor of the number of lines of code called by the test suite and the total number of relative lines of code.

Business Value Delivered – It is a term which denotes the working efficiency of the team. The business objectives are assigned numerical values 1,2,3.. and so on, as per the level of priority, complexity, and ROI.

Defect Removal Awareness – It is the factor that helps the team to deliver a quality product. The identification of an active number of defects, their awareness, and removal plays an important role in delivering a high-quality product.

Defect Resolution Time – It is a procedure through which the team members detect the defects (bugs) and set a priority for the defect resolution. The procedure of fixing errors/bugs or defect resolution comprises of multiple processes such as clearing the picture of defect, schedule defect fixation, completing defect fixation, generation, and handling of resolution report.

Sprint Burn Down Matric – The sprint burndown chart is a graph to represent the number of non-implemented or implemented sprints during as Scrum cycle. This matric helps to track the work completed with the sprint.

—————————————————————————————————————————————-Is it ever suggested to use waterfall over Scrum? If yes, explain when.
Yes, sometimes it is suggested to use a waterfall model over Scrum. It is done when the customer requirements are simple, well-defined, fully understood, predictable, and are not subjected to change until the completion of the project. It may the case that you would haven’t ever used waterfall over Scrum but you need to prepare for such Agile Scrum interview questions.

—————————————————————————————————————————————-Why does Scrum encourage the use of automated testing for projects?
Answer: Scrum encourages the use of automated (automated performance or automated regression) testing to make the fastest possible delivery of the project. While answering this question, you may explain some tools that you have used for automated testing.

Confused about which Scrum Master Certification you should go for? Have a comparison between PSM Vs CSM and get to know which one is the right certification for you!

—————————————————————————————————————————————-What do you know about “Planning Poker” technique?
Answer: Planning poker, also known as Scrum Poker, is a card-based agile technique that is used for planning and estimation. To start a session of planning poker technique, the agile user story is read by the product owner. The steps performed in the poker planning technique are –

Each estimator has a deck of poker cards with the values such as 0, 1, 2, 3, 5, and so on, to denote story points, ideal days or something else that the team uses for estimation.
Each estimator has a discussion with the product owner and then privately selects a card on the basis of their independent estimation.
If the cards with same value are selected by all estimators, it is considered as an estimate. If not, the estimator discusses the high and low value of their estimates.
Then again, each estimator privately selects a card and reveals. This process of poker planning is repeated to reach a general agreement.
Experience-based Agile Scrum Interview Questions
In this section, the questions will be related to the experience you have in agile or scrum. You should be prepared with the data of few of your old projects when answering these experience-based agile scrum interview questions.

—————————————————————————————————————————————-Name some methodologies and development where you have used the Agile scrum model.
Answer: While answering this type of agile scrum interview questions, keep in mind to mention those methodologies that are familiar with. Some of the methodologies and development where the Agile scrum model can be used are –

Crystal methodologies
Lean software development
Dynamic development
Feature-driven development

Share your experience as a Scrum Master/Product Owner/Agile team member and what were your primary responsibilities?
Answer: Here you have to explain your project details where you worked in Scrum team and defining your role with the responsibilities you held. The trick in this question is whether while explaining you are showing self-organizing and self-motivational team.

Also, the interviewer will try to judge how in depth you have worked in the agile/scrum environment based on your explanation.

—————————————————————————————————————————————-What was the length of sprints/iterations in your project?
Answer: This is probably the most common question asked in agile interviews. The idea here is to judge in which kind of environment you have worked. There will be definitely follow up question like was this length fixed in the beginning and never changed? Have you tried with more than this length or less than that?

—————————————————————————————————————————————-Have you ever performed the removal of impediments as a scrum master on behalf of scrum team?
Answer: As the scrum master acts as a coach for his team, he should motivate his team to perform every task. Although he can remove impediments on behalf of scrum team but he should not do this.

It is recommended for a scrum master not to over pamper nor overrule the team. There may be something when the team can face failure, at that time the scrum master should help them. He should guide them with an appropriate method t0 get out of the problem.

Scrum master should prompt his team members to become independent enough to face problems and take a decision by themselves. This is one of the frequently asked scrum master interview questions, so prepare now and get ready to answer.

—————————————————————————————————————————————-Comparative Agile Scrum Interview Questions
Whatever is the field of job, interviewers prefer to ask one or more comparative or difference-based questions. The questions may be from the currently used or previously used technologies. So, here we represent some comparative agile scrum interview questions.

—————————————————————————————————————————————-What is the difference between the agile scrum & traditional way of working?
Answer: This question is to judge whether one is aware of the environment of the agile way of working. Here the answer is expected to cover few or all of below:

The traditional way is sequential where design->Development->Testing etc. happens one after another whereas in agile all of this is done in every iteration/sprint
Changes are welcomed in agile as Scope is flexible whereas in traditional manner scope is fixed in the beginning due to which changes have to follow change request path
Progress is measured with % completion traditionally whereas working software is the measure of progress in agile
Project Manager as a central controlling authority is traditionally driving the project whereas Self-motivated and self-organizing teams drive the projects in agile

—————————————————————————————————————————————-What is the difference between Sprint Planning Meeting and Sprint Retrospective Meeting?
Answer: The difference between Sprint Planning Meeting and Sprint Retrospective Meeting is as follows:

Sprint Planning Meeting – A meeting in which all the Scrum roles (product owner, scrum team, and scrum master) have a discussion about the team’s priority features and product backlog items is known as sprint planning meeting. This meeting is held every week and lasts for almost 1 hour.

Sprint Retrospective Meeting – A meeting in which all the Scrum roles (product owner, scrum team, and scrum master) have a discussion about the good part of the sprint, the bad part of the sprint, and the sprint improvements is known as sprint retrospective meeting.

This meeting that is held at the sprint review meeting or at the end of the sprint; it lasts for 2-3 hours.

This is one of the frequently asked Agile Scrum interview questions. You may be asked to define the above terms separately or the difference between these two.

How is an agile testing methodology different from other testing methodologies?
Answer: Agile scrum interview questions may include a number of questions from agile scrum testing. Let’s understand how you can answer such questions.

The agile testing methodology involves the division of the whole testing process into multiple small segments of codes. In every step, these segments of codes undergo testing. There are a number of additional processes involved in agile testing methodologies such as team communication, strategic modifications for optimal results and many others.

Explain what is Application Binary Interface?

Across different system platforms and environments a specification defining requirements for portability of applications in binary form is known as Application Binary Interface.

—————————————————————————————————————————————-

Explain in Agile, burn-up and burn-down chart?

To track the project progress burnup and burn down, charts are used. Burnup Chart: It shows the progress of stories done over time. Burndown Chart: It shows how much work was left to do overtime.

—————————————————————————————————————————————-

Do you hold any agile certification? Why did you choose this certification?
Answer: Agile and scrum certifications are hot in the market and organizations are expecting the candidates to hold one or more out of it. Certifications generally looked by organizations are:

ACP (Agile Certified Practitioner)
ASM (Agile Scrum Master)
CSM (Certified Scrum Master)
PSM (Professional Scrum Master)
Safe Agilist

—————————————————————————————————————————————-What is the difference between agile & scrum?
Answer: This question will test whether you are aware of a broader picture of agile and its different frameworks or flavors. Below image will help you explain this answer where you can say agile is an umbrella of values and principles and under it, one of the lightweight frameworks is called Scrum.

Certification-related Agile Scrum Interview Questions
Certifications have become very important these days. Although it’s not compulsory to have a certification for any job position it demonstrates your skills to the employers. So, interviewers include these certification-related agile scrum interview questions in an agile scrum interview.

 

 

As a tester what should be your approach when requirements change continuously?
When requirement keeps changing, continuously agile scrum tester should take following approach
• Write generic test plans and test cases, which focuses on the intent of the requirement rather than its exact details
• To understand the scope of change, work closely with the product owners or business analyst
• Make sure team understand the risks involved in changing requirements especially at the end of the sprint
• Until the feature is stable, and the requirements are finalized, it is best to wait if you are going to automate the feature
• Changes can be kept to a minimum by negotiating or implement the changes in the next sprint

———————————————————————————————————————————–

What is an epic, user stories and task?

Epic: A customer described software feature that is itemized in the product backlog is known as epic. Epics are sub-divided into stories

User Stories: From the client perspective user stories are prepared which defines project or business functions, and it is delivered in a particular sprint as expected.

Task: Further down user stories are broken down into different task

—————————————————————————————————————————————- Explain what is re-factoring?

To improve the performance, the existing code is modified; this is re-factoring. During re-factoring the code functionality remains same

—————————————————————————————————————————– ————Explain how you can measure the velocity of the sprint with varying team capacity?
When planning a sprint usually, the velocity of the sprint is measured on the basis of professional judgement based on historical data. However, the mathematical formula used to measure the velocity of the sprint are,

• 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 man-hours For our scenario second method is applicable.

—————————————————————————————————————————————-
Mention the key difference between sprint backlog and product backlog?
Product backlog: It contains a list of all desired features and is owned by the product owner. Sprint backlog: It is a subset of the product backlog owned by development team and commits to deliver it in a sprint. It is created in Sprint Planning Meeting

—————————————————————————————————————————– ————
Is there any drawback of the Agile scrum model? If yes, explain.
Answer: Yes, there are some drawbacks of the Agile scrum model, some of them are as follows –

It is not easy to make a prediction about the effort required to complete a task. It becomes more problematic in case of large projects as it becomes difficult to get an idea of the total effort required.

At sometimes, it’s not possible to properly focus on the design and documentation of the project

In case the requirements of the client are not understood properly, the final project will not meet the customer requirements. Thus, it will lead to the customer dissatisfaction.

Only the leader who has considerable experience in Agile methodologies is capable to take important decisions. The team members with little or no experience are not involved in decision-making, thus they don’t get chance to advance their knowledge.

It’s not always the case that you will be asked the questions about the characteristics and advantages of the agile and scrum in an agile scrum interview. So, just prepare yourself for the drawbacks and disadvantages related agile scrum interview questions.

—————————————————————————————————————————————-
Define Zero Sprint and Spike in Agile.
Answer: To answer this question, describe Zero Sprint and Agile scrum in detail, as follows –

Zero sprint – Zero Sprint can be defined as the preparation step of the first sprint in Agile. There are some activities that are required to be done before actually starting the project. These activities are considered as the Zero sprint; the examples of such activities are – setting the environment for development, preparation of backlogs etc.

Spike – Spike is the type of story that can be taken between the sprints. Spikes are commonly used for the activities related to the design or technical issues such as research, design, prototyping, and exploration. There are two types of spikes – functional spikes and technical spikes.

Scrum Interview Questions
While going for a scrum job interview, prepare yourself for some good scrum interview questions. You may be asked questions related to scrum master, sprint, story point, sashimi, ceremonies etc. by the interviewer. So, prepare yourself for these scrum interview questions.


Test driven development or TDD is also known as test-driven design. In this method, developer first writes an automated test case which describes new function or improvement and then creates small codes to pass that test, and later re-factors the new code to meet the acceptable standards.

Explain in Agile scrum, burn-up and burn-down chart?

To track the project progress burnup and burn down, charts are used. Burnup Chart: It shows the progress of storiesdone over time. Burndown Chart: It shows how much work was left to do overtime.

—————————————————————————————————————————————-

Explain what is Scrum ban?

Scrum ban is a software development model based on Scrum and Kanban. It is specially designed for project that requires frequent maintenance, having unexpected user stories and programming errors. Using these approach, the team’s workflow is guided in a way that allows minimum completion time for each user story or programming error.

—————————————————————————————————————————————-

What is story points/efforts/ scales?

It is used to discuss the difficulty of the story without assigning actual hours. The most common scale used is a Fibonacci sequence ( 1,2,3,5,8,13,….100) although some teams use linear scale (1,2,3,4….), Powers of 2 (1,2,4,8……) and cloth size (XS, S ,M,L, XL).

—————————————————————————————————————————————-

Explain what is tracer bullet?

The tracer bullet is a spike with the current architecture, the current set of best practices, current technology set which results in production quality code. It is not a throw away code but might just be a narrow implementation of the functionality.

—————————————————————————————————————————– ————
What is a test stub?

A test stub is a small code that replaces an undeveloped or fully developed component within a system being tested. Test stub is designed in such a way that it mimics the actual component by generating specifically known outputs and substitute the actual component.

—————————————————————————————————————————————-

What are the differences between RUP (Rational Unified Process) and Scrum methodologies?

RUP SCRUM
– Formal Cycle is defined across four phases, but some workflows can be concurrent
– Each sprint is a complete cycle – Formal project plan, associated with multiple iterations is used. – No end to end project plan. Each next iteration plan is determined at the end of the current iteration
– Scope is predefined ahead of the project start and documented in the scope document. During the project, scope can be revised.
– It uses a project backlog instead of scope scrum – Artifacts include Scope Document, formal functional requirements package, system architecture document, development plan, test scripts, etc. – Operational software is the only formal artifacts
– Recommended for long term, large, enterprise level projects with medium to high complexity
– Recommended for quick enhancements and organization that are not dependent on a deadline

—————————————————————————————————————————————-

Why Continuous Integration is important for Agile scrum?

Continuous Integration is important for Agile scrum for following reasons.

• It helps to maintain release schedule on time by detecting bugs or integration errors

• Due to frequent agile scrum 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 code-base

• Continuous integration helps to check the impact of work on branches to the main trunk if development work is going on branches using automatic building and merging function

—————————————————————————————————————————– ————Mention what are the Agile scrum quality strategies?
Agile quality strategies are
• Re-factoring
• Non-solo development
• Static and dynamic code analysis
• Reviews and Inspection
• Iteration/sprint demos
• All hands demo
