Agile is the best methodology to meet the demand for accurate projects. It is followed in almost every organization, each member of the agile team is equally responsible to make a decision that may decide the future of the organization.
As a result job postings in this domain are increasing exponentially, if you want to crack the interview of a reputed organization you should be familiar with agile interview questions.
In this list, we will be discussing some frequently asked agile interview questions, so that you can be mentally prepared for the questions.
Agile Interview Questions and Answers
1. What is Agile Methodology?
Agile Methodology is a practice that involves a continuous iteration of development and testing throughout the SDLC (Software development life cycle). In the agile process, both development and testing take place simultaneously.
2. What makes agile methodology different from the traditional waterfall process?
In agile methodology, the testing process takes place parallelly with the development process hence testing time is shortened because fewer features needed to be tested at once.
Whereas, in the traditional waterfall model, testing takes place when the entire product is developed therefore, testing time increases.
3. What are the pros and cons of Agile Methodology?
- More flexible: It is more flexible because it adapts to changes more rapidly than other product management approaches.
- The product gets to market faster: It focuses more on working deliverables, not on perfect deliverables.
- Better Communication: It ensures better communication between customers and developers.
- Poor resource planning: In most cases, developers don't know what their end result will be, it's hard to determine the cost of the product at the start of SDLC.
- Limited documentation: Generally, in agile methodology documentation becomes less detailed and often falls to the back burner.
- Trickier decision-making: It requires an expert to make crucial decisions.
4. What are the different types of agile methodology?
There are several types of agile methodologies, Scrum is the most popular out of those. Other types are:
- Crystal Methodology
- Feature-driven development (FDD)
- Dynamic Software Development Method (DSDM)
- Extreme Programming (XP)
5. What are the different principles of agile testing?
This is a commonly asked agile interview question.
The principles of agile testing are -
- Simple and clean code
- Continuous feedback
- Continuous testing
- Less documentation
- Customer Satisfaction
6. What are the roles in Scrum?
There are mainly three roles in Scrum:
- Project Owner: He has the responsibility to manage the product backlog. He understands the needs and wants of the end-user and provides proper requirements to the team to build a proper product.
- Scrum Master: He ensures the proper workflow of the team so that the sprint gets completed on time.
- Scrum Team: They are the development team, who are dedicated and responsible for the high quality of the work.
7. What is the difference between extreme programming and scrum?
- In the scrum framework, the iterations are usually 1-2 Months long.
- It emphasizes self-organization.
- In scrum, teams can change the priority order of tasks.
- In extreme programming, teamworks for 1-2 weeks only.
- It emphasizes engineering practices.
- A team can’t change the priority order of tasks, they have to follow a predefined priority order.
8. What is Pair programming? Explain its advantages.
It is a frequently asked agile methodology interview question. Pair programming, as the name suggests, is a software development practice where one programmer writes the code and the other one reviews it. There are many advantages of pair programming, some of them are -
- Fewer mistakes & bugs
- Increased code quality
- Faster training.
- Coordination among team members increases.
9. What are burn up and burn down charts?
Both of these charts are used to track the progress of the project.
Burn-up charts are used to represent how much work is completed in the project whereas burn-down charts represent how much work is pending in the project.
10. How do you define Kanban?
It is one of the most popular agile methodology interview questions. Kanban is nothing but a tool that helps the team to keep a close eye on the work progress. Also, the status of development can be seamlessly shared using the ‘kanban board’.
11. What do you mean by “increment” in terms of agile?
Increment is nothing but the sum of all the items in the product backlog that were completed during the sprint and the value of increments in previous sprints.
In simple words, It is the total work completed within current and previous sprints.
12. What are impediments in Scrum? Give some examples.
Impediments are obstacles faced by scrum teams that slow down their pace of work.
In other words, if anything is causing difficulty for scrum teams to get their work done then we refer to that as an impediment.
Impediments can be of any form, some examples are:
- Technical, Organizational problems.
- Business problems.
- Lack of skill or knowledge
- Unavailable team member(s).
- External issues like weather, natural calamities, etc.
13. What do you know about ‘scrum of scrums’?
In large organizations, multiple teams are involved in a single project and hence each team holds its scrum meeting. To maintain coordination among different teams, the scrum of scrums technique is used that offers a way to connect multiple teams to work together efficiently.
14. What do you mean by zero sprints in agile?
This is one of the most important agile methodology interview questions.
In agile methodology, zero sprints refer to the first steps that need to be taken before beginning with the project like setting up the development environment, installing various dependencies, preparing backlogs, etc. Generally, this is done before the actual development process starts.
15. What is Scrumban?
Scrumban is a hybrid of scrum and kanban agile development methodology. This technique is used in projects which require continuous maintenance. This method focuses on the faster completion of the project.
16. What are the various tools that are used in a Scrum project?
Tools that are used in the Scrum projects are:
- JIRA (by Atlassian)
- Version One
- RTC Jazz
- QuickScrum, etc.
17. What are some cons of using Scrum?
- Scrum can only be successful only with experienced team members.
- A Less experienced scrum master can become the cause of the collapse of a project.
- Adopting Scrum in a large team can be challenging.
- Daily meetings sometimes frustrate team members.
18. What is the difference between product backlog and sprint backlog?
- It is owned by the Project owner.
- It contains all the features and the requirements of the end product.
- It is more specific to the end goal of the product.
- It is owned by the development team.
- It only contains the features and the requirements of a particular sprint.
- It is more specific to the sprint goal of a particular sprint.
19. What do you mean by “velocity” is the agile methodology?
As suggested by the name, Velocity is the measurement unit to calculate how much work a development team can complete in a sprint, which helps to calculate how much time is needed to finish the project.
It is used as a calibration tool extensively used by development teams to create accurate and effective timelines.
20. What is a Sprint Planning Meeting, Sprint Review Meeting, and Sprint Retrospective Meeting?
Sprint Planning meeting:
- In this meeting, important product features and backlog items are discussed.
- This is usually attended by the project owner, Scrum Master, and Scrum team.
- Generally, this is held once a week and lasts about an hour.
Sprint Review Meeting:
- In this meeting, the scrum team demonstrates development in the product.
- The project owner determines which tasks are completed and which are not and he may also add some items in the project backlog based on the feedback from the end-users/customers.
- It is held after each sprint to inspect what are the developments of the sprint and to modify it if required.
Sprint Retrospective Meeting:
- In this meeting, the Scrum team inspects itself, discusses past mistakes, and analyzes solutions to potential issues.
- The main purpose of this meeting is to smoothen the development process.
- It is held after the Sprint Planning meeting and lasts about 2 to 3 hours.
