Interview Prompt
We show customers one unified view of their spending across their connected bank accounts. The data arrives from dozens of partner integrations, each delivering by webhook, scheduled file, or CDC, and compliance must be able to reproduce every number we serve. Design the data pipeline.
Summary
Bad data in fintech is not just messy. It is expensive.
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
