Your question is Trends and Anomalies Detection. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Given a dataset, how would you identify key trends or anomalies?
Explain how you would validate the data, summarize changes over time, select appropriate comparison groups, and distinguish meaningful business signals from normal variation or data-quality problems. Describe the outputs you would provide to stakeholders, including visualizations, supporting metrics, and recommended follow-up analysis.
