Interview Prompt
We run a cloud EHR platform for thousands of medical practices, all sharing one database where tenant isolation lives only in the application layer. Design the pipeline that serves both cross-practice population health analytics and each practice's own performance reporting from that database.
Summary
Patient records in, operational insights out.
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
