How to answer (STAR + numbers)
Use STAR but bias to Action and Result — interviewers don't need the full backstory. 20% Situation, 60% Action + Result, 20% reflection.
What interviewers are quietly scoring
Across every data structures round, the single signal that decides close calls is: curiosity through the questions you ask back. Make sure at least two of your stories show it.
