Interview Prompt
Our live operations dashboard trails reality by minutes, and its counts disagree with the numbers analysts later pull from history, on a platform ingesting about 5 billion user-interaction events a day. Design the pipeline that serves both the dashboard and the analysts' ad-hoc queries over years of events.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your pipeline on the design canvas: sources, transforms, storage and checks
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
