What is Definition of Ready and why must the PO uphold it?
Tests grasp of backlog refinement as a team agreement. Strong answers define ready as value, scope, and acceptance criteria; explain it stops mid-sprint churn; and cite dependencies mapped and designs attached.
How do you handle a mid-Sprint urgent feature request?
Send the stakeholder to the Product Owner; do not add directly to the Sprint Backlog; protect the current plan.
How do the Sprint Retrospective and Definition of Done support empiricism?
Tests if you see the DoD as a transparency standard and the Retrospective as inspect-and-adapt. Explain that the DoD makes true progress visible, enabling honest inspection, while the Retrospective inspects process and adapts the DoD.
Stakeholder approaches mid-sprint with a feature request. What is the Scrum process?
Tests whether you know the Product Owner orders the backlog and the Sprint selection is fixed. Strong answer: send the stakeholder to the PO, who decides placement. Red flag: adding the work to the Sprint Backlog yourself.
How is work selected and forecasted for the Sprint Backlog?
Tests empirical forecasting. Outline: the team selects from the ordered Product Backlog using observed experience and expertise to create one valuable Increment. Red flag: treating the forecast as a hard commitment or citing velocity as a required input.
How do items flow between the Product Backlog, Sprint Backlog, and Increment?
Tests whether you understand Scrum's three artifacts as commitments to value, not just task lists. A strong answer describes ordering, selection, and the Definition of Done. Red flag: calling the Sprint Backlog a task list owned by the Product Owner.
Describe the Daily Scrum's purpose, audience, and intended outcome.
Say it's a Sprint event for Developers to inspect progress toward agreed goals and adapt their plan.
Three accountabilities in a Scrum Team and their primary focuses
Tests recall of the three Scrum accountabilities. Outline: Product Owner orders the backlog; Developers create an Increment each Sprint; Scrum Master fosters an environment for empiricism. Red flag: Using roles or treating the Scrum Master as a task master.
How would you implement a software Andon Cord equivalent?
This tests translating Lean stop-the-line into CI/CD culture. Trigger: compile, test, or integration failures. Impact: halt pipeline, block merges, and swarm to fix immediately with collective ownership. Red flag: blaming committers or deferring fixes.
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.
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.
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 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.
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.
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.
Navigate between feature modules without direct dependencies?
Tests dependency inversion in modular apps. Answer by defining navigation interfaces in a shared module, implementing them in the :app module, and using DI to connect them. A red flag is suggesting direct module dependencies or using reflection for navigation.
Combine two network sources using Coroutines and Flow
Tests your grasp of async data combination and state management. A good answer uses Flow.combine in a ViewModel, fed by a Repository, emitting a sealed class for UI state (Loading, Success, Error). A red flag is trying to combine state in the UI layer itself.
Explain the purpose of a UseCase or Interactor layer
Tests your grasp of separation of concerns. A great answer defines a UseCase as a single, reusable business operation that sits between the ViewModel and Repository. It keeps other layers clean and focused.
How do you share a ViewModel between Fragments?
Tests your understanding of ViewModel lifecycle scoping beyond a single screen. To share, scope the ViewModel to the parent Activity or a navigation graph using activityViewModels() or navGraphViewModels().
How to use a nested navigation graph for a login flow?
Tests your ability to structure complex UI flows using Navigation Component. A great answer defines a separate login graph XML, includes it in the main graph, and navigates to the graph's ID. This encapsulates the flow, making it reusable.
