Answer it first, then compare. Nothing here is saved or scored.

Model answer

Quality is everyone's responsibility, not just QA's. Implementation: (1) Developers write unit tests, it's part of "done." (2) QA provides test infrastructure and guidance, not just test execution. (3) Define quality criteria in the definition of done - tests pass, no critical bugs, a11y checked. (4) Shared quality dashboards visible to the whole team. (5) QA participates in design reviews, not just test execution. (6) Post-mortem culture - production bugs are learning opportunities, not blame. (7) Celebrate quality wins - recognize developers who write great tests. The QA engineer's role evolves from tester to quality coach.

What interviewers listen for

Risk-based prioritisation
You can defend skipping coverage on a path because the risk maths supports it.
Test design fluency
You apply equivalence partitioning and decision tables to concrete inputs in real time.
Metric judgment
You distinguish between metrics that drive learning and metrics that drive theatre.
Strategy under constraint
You can produce a defensible plan when the team has half the time and twice the scope.
