Interview Prompt
Design the pipeline that takes transaction feeds from the third-party bank aggregators our loyalty app links users' accounts through, and turns purchases at partner brands into reward points in each user's balance.
Summary
The bank data shows up late. The rewards were already sent.
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
