Interview questions in Agile & Scrum
How does 'Individuals and interactions' shape team structure and communication?
Say teams should be cross-functional and favor direct communication like pairing and standups over mandated tool workflows.
Individuals & Interactions Over Processes & Tools: Explain This Value
Tests your grasp of Agile's core philosophy: empowering people over rigid systems. A great answer defines the principle, links it to cross-functional team structures, and champions direct communication over ticket-passing.
Individuals and Interactions Over Processes and Tools
Tests if you can apply Agile's core human-centric value. A great answer defines the principle, then links it to concrete team structures (co-located, cross-functional) and communication methods (face-to-face). A red flag is dismissing all processes and tools.
Primary goal of a retrospective and its tie to continuous improvement
State the goal is improving quality, tie it to Scrum's empirical pillars, and demand adaptations.
Goal of a Retrospective and Continuous Improvement
Tests if you see process improvement as a core engineering duty. A great answer defines the retro's goal (inspect & adapt the process), its output (actionable items for the next Sprint), and its role as the engine of continuous improvement.
What is the goal of a sprint retrospective?
Tests if you see retrospectives as actionable process improvement, not just venting. A good answer defines the retro's purpose (inspecting the sprint's people, processes, tools) and explains how it creates concrete action items for the next sprint.
How would you apply Agile simplicity when implementing a new feature?
Validate the smallest user-problem slice; defer gold-plating and custom abstractions; prefer existing tools.
Explain the Agile principle of Simplicity and how you apply it.
This tests your ability to connect Agile theory to engineering practice. A good answer defines simplicity as maximizing work not done, applies YAGNI with a concrete example (e.g., phased feature rollout), and links it to business value.
Explain 'Simplicity' and how you apply it as an engineer
Tests if you see simplicity as maximizing value, not just minimizing code. A good answer defines it as avoiding unneeded work, then explains how you'd build an MVP, defer gold-plating, and validate scope with product.
How do you decide appropriate documentation levels without creating unnecessary overhead?
This tests balancing Manifesto values with operational reality. Strong answers define audience first, favor living docs over static artifacts, and calibrate depth to team topology and lifecycle stage. Red flag: using the Manifesto to justify no documentation.
How do you decide the right level of project documentation?
This tests your pragmatism beyond literal Agile interpretation. A great answer defines docs as a product for a specific user, ties value to reducing future work, and proposes a tiered approach. A red flag is treating all documentation as pure overhead.
How do you apply 'working software over comprehensive documentation'?
This tests your ability to balance velocity with maintainability. A great answer defines docs by audience and purpose (onboarding, ops), prioritizes "living" docs like tests, and uses a just-in-time approach. A red flag is treating this as "no documentation."
Explain Lean Muda and give three software lifecycle waste examples with mitigations
Tests mapping Lean waste to software with concrete countermeasures. A strong answer defines Muda as non-value-add work, cites three distinct types like waiting, defects, or overproduction, and pairs each with a specific practice.
Explain Muda (Waste) with three software development examples
Tests your ability to apply Lean's 'Muda' (waste) concept to software. A good answer defines Muda, then gives 3 examples like partially done work or extra features, with specific mitigations like WIP limits or YAGNI. A red flag is giving generic examples.
Explain the Lean concept of 'Muda' (Waste)
Tests applying manufacturing principles to software. Define Muda as non-value-adding work. Cite 3 software wastes like partially done work, extra features, or defects, and offer specific mitigations like smaller batches, YAGNI, or TDD.
How does Agile welcome changing requirements without chaos?
Whether you know that Agile embraces change only when supported by engineering discipline. Distinguish planned adaptability from reactive chaos by citing short feedback loops, evolutionary architecture, and continuous integration.
Agile Change vs. Chaos: Technical Enablers
Tests if you know Agile is disciplined, not chaotic. A great answer contrasts structured, time-boxed change with reactive chaos, then details technical enablers like CI/CD and loose coupling. A red flag is equating Agile with no planning.
How does Agile's 'welcoming change' differ from chaos?
Tests if you know Agile flexibility requires engineering discipline. Answer by defining the difference (discipline vs. chaos), listing technical practices (TDD, CI/CD), and naming architectural patterns (modular design).
Describe the relationship between Jidoka and TDD/CI
Jidoka is stop-the-line; map TDD to unit detection and CI to build verification; show shift-left.
Relate Lean's 'Build Quality In' to TDD and CI
This tests your ability to connect historical Lean principles to modern software development. Explain Jidoka as "stop the line," then frame TDD and CI as its software equivalents that prevent defects from propagating.
