Welcome to your interview for the Data Scientist role at Radiant Digital.
The question is on your right: Validate Results Before Presenting. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen. You have three graded attempts to score 7/10 or better.
You have finished an analysis and built a model, and now you need to present the results to technical and non-technical stakeholders. Before you share conclusions, you want to confirm that the reported performance is stable, correctly measured, and not driven by a bad split, poor calibration, or a misleading aggregate metric.
How do you validate your results before presenting them?
