Interview Prompt

The claims, member and provider databases run on three different engines and take about 225K changes a day, and their owners will grant replication access to the transaction logs but nothing else. The platform lead needs a pipeline that retires the six-hour nightly export into the analytics warehouse: design it.

Summary

Healthcare claims change constantly. The warehouse cannot fall behind.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Draw your pipeline on the design canvas: sources, transforms, storage and checks
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
