Welcome to your interview for the Data Engineer role at Royal Caribbean Group.
The question is on your right: Real-Time Dashboard Pipeline Design. 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 are starting a new analytics pipeline for dashboards that need fresh data within minutes. The main concern is how to move events from source systems through processing and into a serving layer without stale metrics or broken refreshes.
What is your approach to building dashboards for real-time or near-real-time reporting?
