Interview Prompt
Design a risk data pipeline that computes intraday margin from live trades and market prices across fixed income, FX and derivatives books, about 2 million trades a day. The desk's risk lead still gets risk only from a nightly batch, and Canadian regulators hold every reported figure to BCBS 239 lineage.
Summary
Intraday risk, full lineage. The regulator is watching.
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
