Asked in the manager behavioral stage. The interviewer is assessing how you respond when reality differs from your assumptions, including whether you take ownership, adapt your approach, and communicate clearly. A strong answer should focus on one specific event, explain the original expectation and outcome, describe the corrective actions you took, and quantify the result where possible. Conclude with what you learned and how that lesson changed your subsequent decisions.
