Measure successMedium

Problem. Your team built a detector for anomalous data exports by employees with legitimate access. It is ready to ship. How would you define success, and what would make you say it worked?

Before you reveal: say your answer out loud, as if you were in the real interview — get your reasoning across clearly first. There is no single correct answer: reading what the interviewer is really after and defending your own thinking is what makes an answer strong.
