Asked in the Behavioral / project deep-dive stage. Be prepared to explain what made the project complex, how you established priorities, aligned stakeholders, managed risks, and handled ambiguity. The interviewer is assessing whether you personally drove the work rather than simply participating in it. Strong responses use a specific example, clarify your ownership, describe consequential decisions and trade-offs, and close with measurable outcomes and a lesson learned.
