Interview Prompt
Credit models are running on week-old data for the risk team, even though decisions happen in real time and repayments stream in continuously across thousands of applications a day. Design a Kafka-based pipeline that delivers loan application events, credit decisions, and repayment data to the risk analytics layer within minutes of occurrence.
Summary
Loan approved. Loan denied. Every decision is an event.
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
