Scrum Master Interview Questions for Freshers
Q1. What is Scrum?
Ans: Scrum is an agile framework used for developing, delivering, and sustaining complex products. It is designed to enable teams to work collaboratively and iteratively in short, time-boxed cycles called sprints. Scrum emphasizes transparency, inspection, and adaptation. Key roles within Scrum include the Scrum Master, who facilitates the process; the Product Owner, who defines the product vision and backlog; and the Development Team, who build the product. Scrum also includes specific events such as Sprint Planning, Daily Stand-ups, Sprint Reviews, and Sprint Retrospectives to ensure continuous improvement and alignment.
Q2. What does the acronym INVEST stand for?
Ans: The acronym INVEST stands for:
- Independent: Each story should be self-contained, so it doesn’t depend on other stories.
- Negotiable: Stories are not contracts; they are reminders of features to be discussed and refined.
- Valuable: Each story should provide value to the customer or user.
- Estimable: Stories should be small enough to be estimated with reasonable accuracy.
- Small: Stories should be small enough to be completed in a single sprint.
- Testable: Stories should be able to be tested to confirm that they are complete and correct.
Q3. What happens in Daily Stand-up sessions?
Ans: In Daily Stand-up sessions, also known as Daily Scrums, team members discuss:
- What they did yesterday: This provides context and continuity.
- What they plan to do today: This helps with planning and coordination.
- Any impediments they’re facing: This allows the team to address obstacles that might impede progress.
The Daily Stand-up is a short, time-boxed event (usually 15 minutes) aimed at fostering collaboration, synchronization, and quick identification of issues.
Q4. What are the responsibilities of the Scrum Team?
Ans: The Scrum Team is responsible for delivering a potentially shippable product increment at the end of each sprint. The team includes:
- Product Owner: Manages the product backlog, prioritizes features, and ensures the team works on the most valuable tasks.
- Scrum Master: Facilitates Scrum practices, removes impediments, and supports the team in continuous improvement.
- Development Team: Self-organizes to develop and deliver product increments. They are responsible for all aspects of product development, including design, coding, testing, and documentation.
Q5. What happens in a Sprint Retrospective?
Ans: In a Sprint Retrospective, the Scrum Team:
- Reflects on the past sprint: The team reviews what went well and what didn’t.
- Identifies improvements: They discuss areas for improvement.
- Plans actionable steps: The team agrees on specific actions to implement in the next sprint.
The goal of the Sprint Retrospective is continuous improvement by learning from past experiences and enhancing future performance.
Q6. What is Empirical Process Control in Scrum?
Ans: Empirical Process Control is a core principle of Scrum that relies on three main ideas:
- Transparency: Ensuring that all aspects of the process are visible to those responsible for the outcome.
- Inspection: Regularly examining Scrum artifacts and progress toward the Sprint Goal to detect variances.
- Adaptation: Making adjustments as soon as possible to minimize further deviation.
This approach allows teams to make informed decisions based on the reality of the project, rather than predictions.
Q7. Differentiate Between Agile and Scrum?
Ans:
- Agile: Agile is a broad philosophy encompassing various methodologies aimed at improving flexibility, collaboration, and customer satisfaction in software development. It is defined by the Agile Manifesto and its principles.
- Scrum: Scrum is a specific framework within the Agile philosophy. It provides a structured way of implementing Agile practices, with defined roles, events, and artifacts to guide the team in iterative development.
Q8. What are the techniques for estimation in Scrum?
Ans: Common techniques for estimation in Scrum include:
- Planning Poker: Team members use cards to estimate effort required for user stories, fostering discussion and consensus.
- T-shirt Sizing: Stories are categorized into sizes (XS, S, M, L, XL) to represent the relative effort required.

Q9. What is Scrum-ban?
Ans: Scrum-ban is a hybrid approach combining elements of Scrum and Kanban. It is designed to provide the structure of Scrum with the flexibility of Kanban. Scrum-ban is often used in projects requiring continuous flow or maintenance work, where the time-boxed sprints of Scrum may be less effective. Key elements include:
- Pull-based workflow: Tasks are pulled as capacity permits rather than pushed based on a sprint cycle.
- WIP limits: Work-in-progress limits control the number of tasks in each stage of the workflow to maintain focus and quality.
Q10. What is the distinction between MVP and MMP?
Ans:
- MVP (Minimum Viable Product): The simplest version of a product that can be released to early adopters to validate assumptions and gather feedback.
- MMP (Minimum Marketable Product): A more complete version of a product that has enough features to be marketed and sold to a broader audience.
Q11. What is timeboxing in Scrum?
Ans: Timeboxing is the practice of setting fixed, maximum durations for activities or tasks. In Scrum, timeboxing helps maintain focus and discipline, ensuring that meetings and activities do not overrun and that work progresses at a steady pace. Examples include:
- Sprints: Typically 1-4 weeks.
- Daily Stand-ups: 15 minutes.
- Sprint Planning: Time-boxed to 2 hours per week of sprint duration.
Q12. How can you stop fatigue at retrospectives?

Q14. What is Scope creep, and how do you handle it?
Ans: Scope creep refers to the uncontrolled expansion of product or project scope without corresponding adjustments to time, cost, and resources. It can be handled by:
- Clear requirements: Ensuring requirements are well-defined and understood.
- Change control process: Implementing a formal process for evaluating and approving changes.

Q19. What is DoD?
Ans: DoD stands for Definition of Done, a shared understanding of what it means for work to be considered complete. It ensures transparency and quality by defining criteria that a product increment must meet to be considered done. This includes coding standards, testing requirements, documentation, and other quality controls.
Q20. How would you handle conflict within the team?
Ans: To handle conflict within the team:
- Encourage open communication: Create a safe space for team members to express their concerns.
- Address issues early: Tackle conflicts as soon as they arise to prevent escalation.
