Interview Prompt
Card transactions hit the payment gateway at roughly 10,000 per second, and each one is scored for fraud by a scorer the gateway must never wait on. Design the pipeline that scores them and keeps the fraud model learning.
Summary
The fraudsters move fast. Your pipeline has to move faster.
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
