Interview Prompt
Energy price ticks peak at 50,000 a second and twelve desks send about 300 trade executions a second between them, each desk feed replaying its last few minutes whenever it reconnects. Design the pipeline that brings our market prices, executed trades and open positions together for the risk managers who watch exposure through the trading day.
Summary
Markets move in milliseconds. The pipeline has to keep up.
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
