Decomposing a Monolith: Technical Strategy
This tests your ability to create a practical, phased migration strategy from monolith to microservices. A strong answer defines service boundaries via Bounded Contexts, manages data with events, and uses an API Gateway for contracts.
Estimating Cross-Team Initiatives in PI Planning
This tests your ability to lead multi-team estimation. A good answer covers decomposing work, bottom-up team estimates, mapping dependencies, and synthesizing a risk-assessed plan. A red flag is a single top-down estimate that ignores team capacity.
Technical Prerequisites for LeSS Feature Teams
Tests if you can link agile structure to technical architecture. A great answer covers codebase design for shared ownership, a fast CI pipeline for frequent integration, and a robust automated testing strategy.
Design and Implement an Upstream Kanban Process
Tests your understanding of managing demand vs. capability. A great answer defines Upstream Kanban as a pre-commitment filter, outlines board stages and policies, and explains how vetting work improves downstream predictability.
Diagnosing a Widening CFD 'Testing' Band
Tests your ability to interpret a CFD and propose data-driven experiments. A widening 'Testing' band means work enters faster than it leaves. Diagnose with experiments (e.g., tracking test failures, environment downtime) before proposing solutions.
How would you implement Classes of Service in Kanban?
This tests your understanding of risk management and differentiated service delivery. A good answer defines the 4 classes (Expedite, Fixed Date, Standard, Intangible), explains their different pull policies, and gives a risk-based example.
How do you strategically manage tech debt during product discovery?
This tests your strategic view of tech debt. A great answer defines intentional vs. unintentional debt, outlines a framework for tracking and repayment (like a debt backlog), and explains when it's a valid tool for MVPs.
MVP vs. Throwaway Prototype: Technical Differences
This tests your understanding of Minimum Viable Architecture (MVA). Differentiate by intent: a prototype is a throwaway concept test, while an MVP is a sustainable first version built on an MVA. A red flag is describing a sacrificial architecture for an MVP.
How would you A/B test a redesigned dashboard?
Tests translating a vague goal ('more engagement') into a concrete engineering plan. A good answer defines key metrics first, then outlines user bucketing, instrumentation, and statistical analysis.
How do you fix an inverted test pyramid?
This tests your ability to create a pragmatic, multi-sprint plan to improve test suite health. A good answer involves analyzing tests, getting buy-in, then incrementally adding unit/integration tests while refactoring old E2E tests.
Trunk-Based Development vs. GitFlow for High-Frequency Releases
This tests your grasp of modern release strategy. Explain how TBD enables frequent merges to main, while feature toggles decouple deployment from release for safety. Contrast this with GitFlow's versioned release model.
What is the Strangler Fig pattern?
Tests your understanding of gradual legacy system modernization. A good answer defines the pattern (new system grows around old), outlines the steps (identify seams, build, redirect traffic), and links it to Agile's incremental value delivery.
Describe a CI/CD pipeline for a containerized web app
This tests your grasp of automated quality control in software delivery. A strong answer details the CI, build, staging, and production stages, emphasizing quality gates like security scans and E2E tests.
Explain the Test Pyramid and how it guides your strategy.
Tests your grasp of balanced automated testing. Define the pyramid's layers (Unit, Service, UI), explain trade-offs like speed and cost, then apply it to a new service. A red flag is describing the layers without explaining the 'why' behind the shape.
How do you fix a team that consistently overcommits in sprints?
This tests diagnosing process failures, not just bad estimates. A good answer investigates root causes like external pressure or poor refinement, then proposes using historical velocity and tracking actual capacity.
How would you break down an epic into user stories?
Tests your ability to turn business goals into independent engineering tasks. A great answer maps user journeys, breaks work into vertical slices, defines acceptance criteria, and prioritizes by value.
How does a self-managing team handle technical disagreements?
This tests your ability to facilitate productive conflict, not just win arguments. A great answer outlines structured techniques like timeboxing dialogue and multi-voting with reasoning. A red flag is suggesting the senior dev acts as the sole tie-breaker.
How do you resolve cross-team friction from local optimizations?
Tests your ability to think beyond your team and address systemic, organizational impediments. A good answer involves gathering data, facilitating cross-team communication, and proposing systemic solutions.
What is the Definition of Ready for a backlog item?
Tests your grasp of upstream quality gates in Agile. Define DoR as a team's checklist for sprint-ready items, explain it protects dev focus and predictability, and give examples like clear acceptance criteria.
How would you implement an Andon Cord for a software team?
Tests your grasp of CI/CD, quality, and team culture. A great answer defines a trigger (broken main build), a technical block (stop merges), and a cultural response (team swarms). A red flag is scheduling the fix or blaming an individual.
