Welcome to your interview.
The question is on your right: Real-Time Dashboard Data Pipeline. 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 (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You are building the data pipeline behind operational dashboards for a utility analytics team. The dashboards need fresh metrics from event data, and the team wants to understand how to keep the pipeline current without breaking data quality or duplicating records.
How do you handle real-time data in your visualizations?
