Interview Prompt
MiFID II transaction reports arrive as files from tens of thousands of regulated firms, each formatted slightly differently. The pipeline has to ingest these files, normalize them to a canonical schema, validate them against regulatory rules, and produce an immutable record that auditors can query years later. Design it end-to-end.
Summary
The regulator changed the format. Again. Handle it.
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
