Which Scrum event fixes consistently failed Sprints?

WHAT THIS TESTS: This question tests your understanding of Scrum's core purpose: empiricism and process improvement. The interviewer wants to see if you know WHY the events exist, not just what they are. It specifically probes your ability to distinguish between inspecting the product (what was built) and inspecting the process (how it was built). A senior engineer is expected to drive process improvement, and this question identifies if you know the correct forum for it.

A GOOD ANSWER COVERS: First, directly state the Sprint Retrospective is the most critical event. Second, explain that its explicit purpose, per the Scrum Guide, is for the team to inspect itself and create a plan for improvements to be enacted during the next Sprint. Third, contrast this with other events. The Sprint Review is for inspecting the Increment and adapting the Product Backlog with stakeholders. The Daily Scrum is a 15-minute tactical meeting for the Developers to plan their next 24 hours, not for deep, systemic problem-solving. Fourth, emphasize the outcome: the Retrospective generates at least one actionable process improvement that goes into the next Sprint Backlog.

COMMON WRONG ANSWERS: The most common wrong answer is the Sprint Review. This is a major red flag because it confuses inspecting the product with inspecting the process. The Review's focus is on stakeholder feedback about the Increment, not a frank, internal discussion about why the team is failing. The presence of external stakeholders often prevents the psychological safety needed to discuss internal dysfunctions. Another wrong answer is the Daily Scrum. While problems may be mentioned there, its 15-minute timebox is insufficient for root cause analysis of a recurring, systemic failure. It's for tactical, not strategic, adaptation.

LIKELY FOLLOW-UPS: Expect follow-ups like: "What if the Retrospectives are happening, but nothing improves? What would you do?" This tests your leadership and ability to influence change. Or, "Give me a concrete example of a problem and the specific improvement that would come out of a Retrospective to address it."

ONE CONCRETE EXAMPLE: A team consistently delivers buggy software, failing to produce a usable Increment. During the Sprint Retrospective, they discover their Definition of Done is too weak; it doesn't include integration testing. The team's actionable improvement is to update their Definition of Done to require that 'all new work is successfully integration tested against the main branch before being considered done.' They then add tasks to their future Sprint work to account for this, making the improvement concrete and visible.
