Interview Prompt
Workout events arrive as webhooks from three providers in three formats, and about a third of sessions are reported by two or more of them. Each event carries the session's score with raw heart rate and GPS. Design the pipeline from those webhooks to a live leaderboard and to the permissioned readers of health data.
Summary
The same ride, reported three times.
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
