Interview Prompt

Our bank runs a Databricks platform for transaction analytics. The pipelines are functional but slow - a daily job that should finish in 45 minutes is taking 3.5 hours, and the team has been throwing more compute at it without understanding the root cause. Design the optimized pipeline architecture and the performance remediation plan that resolves the Spark bottlenecks.

How This Interview Works

1. Read the vague prompt (just like a real interview)
2. Ask clarifying questions to the AI interviewer
3. Write your pipeline design solution with real code execution
4. Get instant feedback and a hire/no-hire decision
