Interview Prompt
Our market data provider bills per request, goes dark for hours a few times a year, and its license requires us to keep every raw file unchanged for audit. We need the prior day's price and volume data pulled automatically and loaded into our research database before pre-market models start at 7am. Design the ingestion pipeline.
Summary
The models run at dawn. The data has to be there first.
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
