Interview Q&A

Short answer: In Scrum, scope creep is managed by controlling what goes into a Sprint — not by freezing the entire project.

Explain a bit more

How it’s handled: Sprint scope is locked once planning ends. No changes mid-Sprint without discussion and agreement. Product Backlog remains flexible, so new ideas or requirements are added there — not injected into the current Sprint. The Product Owner (PO) decides what gets prioritized for future Sprints. Example: If a stakeholder requests a new login method during the Sprint, the PO thanks them, adds it to the Product Backlog, and it’s considered in the next planning session — not immediately worked on.

Real-world example (ShopNest)

Agile for ShopNest means ship a thin checkout slice every sprint, get feedback, then improve—not a 6-month big-bang release.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.

Short answer: Fibonacci scale: 1, 2, 3, 5, 8, etc. Focus on effort, complexity, and risk — not time.

Real-world example (ShopNest)

“Add UPI” is a story with acceptance criteria. Points reflect effort/risk, not days on a calendar.

3. Trade-off — when you would not use it.

Short answer: A Scrum Team is composed of three primary roles: Product Owner – Responsible for maximizing the value of the product and managing the Product Backlog. Scrum Master – Acts as a servant-leader, facilitating the Scrum process and removing impediments. Development Team – A cross-functional group that builds the product increment each Sprint.

Example code

In a software startup developing a new mobile app, the Product Owner gathers customer needs and prioritizes them. The Scrum Master ensures daily stand-ups run smoothly and helps remove blockers like server access issues. The Development Team (UI/UX designers, front-end and back-end developers) work together to deliver usable features every two weeks. Follow On:

Short answer: login screen might be a 2-point story (simple, well understood). A feature with integrations nd security considerations may be 8 points due to complexity and risk. Pro Tip: void estimating in hours — it introduces false precision. Focus on relative effort, not duration.

Short answer: Top challenges: Follow On: Team alignment across multiple squads Coordination of dependencies Shared ownership of product vision Overhead from meetings multiplying with team size Consistent backlog management Resistance to organizational culture change Example: If 10 Scrum teams are working on the same e-commerce platform, ensuring consistent UI standards and integrating features becomes increasingly difficult…

Short answer: Effort is typically estimated using relative sizing methods: ✅ Story Points (most common) ✅ Planning Poker (a team-based game using consensus to estimate) ✅ T-shirt sizes (S, M, L, etc., for quick high-level sizing) Story Points consider: Complexity Amount of work Risks or unknowns

Example code

A login screen might be a 2-point story (simple, well understood). A feature with integrations and security considerations may be 8 points due to complexity and risk. Pro Tip: Avoid estimating in hours — it introduces false precision. Focus on relative effort, not duration.

Explain a bit more

Effort Matrix Weighted Shortest Job First (WSJF) in SAFe Factors to consider: Customer value Business impact Risk reduction Dependencies Follow On: Technical feasibility Example: A travel app team uses Value vs. Effort to prioritize. “In-app booking” has high value and moderate effort, while “Flight status tracking” has high effort and low impact — so the former gets scheduled first.

Short answer: Purpose: The Daily Scrum is a 15-minute timeboxed event for the Development Team to inspect progress toward the Sprint Goal and adapt the plan.

Explain a bit more

Effective format (common but not mandatory): What did I do yesterday? What will I do today? Are there any blockers? Best Practices: Follow On: Same time, same place daily. Focus on progress toward the Sprint Goal. Keep it short and to the point. Real-World Example: During a mobile app Sprint, a developer mentions a deployment delay due to a configuration issue. The Scrum Master takes note and helps resolve it after the meeting — preventing a bottleneck.

Short answer: Scrum defines three key artifacts: Product Backlog – A prioritized list of everything that might be needed in the product, maintained by the Product Owner.

Explain a bit more

Sprint Backlog – A subset of the Product Backlog items selected for the current Sprint, along with a plan for delivering them. Increment – The sum of all completed work that meets the Definition of Done at the end of a Sprint. Example: If your product is an e-commerce website, the Product Backlog could include features like "Add to Cart", "Payment Gateway", and "User Login". In the current Sprint, the Sprint Backlog may include just “User Login” and “Add to Cart”. At the end of the Sprint, a working login system is delivered as the Increment.

Cross-functionality: Ensure the team has all necessary skills. Scrum Master: Coaches the team, but doesn’t assign tasks. Encourage decision-making within the team. Follow On: Example: Instead of… telling the team……… who should build the new feature, let them decide who does…

Short answer: Purpose: To inspect the Increment and adapt the Product Backlog based on feedback.

Explain a bit more

It’s a collaborative working session, not a demo-only meeting. Key components: Presentation of what was "Done" in the Sprint. Discussion on what went well and challenges faced. Stakeholder feedback on the Increment. Review of the market or business context. Real-World Example: The team presents a new analytics dashboard to stakeholders. Marketing suggests a change in how data is grouped. The Product Owner logs this feedback into the Product Backlog for future refinement.

Short answer: Definition: The Sprint Backlog is a subset of Product Backlog items the team commits to deliver in a Sprint, plus a plan for how to achieve it.

Explain a bit more

How to manage it: Keep it visible and up to date (via a Scrum board or tool like Jira). Break down items into tasks during Sprint Planning. Update daily during stand-ups based on progress. Add tasks if necessary, but don’t change Sprint scope without discussion. Example: A team uses a Kanban board with “To Do”, “In Progress”, and “Done” columns. Every day, they update task statuses so progress is clear and blockers are quickly identified.
