Evaluate a detector when you have no labels
Measurement & estimationHardProblem. You built an unsupervised detector for a new attack technique. There are no labeled examples: it has never been seen at Salesforce. Your manager asks how good it is. How do you answer?
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.
