Interview Prompt

We're a data services company and our enterprise client sends us two kinds of data: a continuous stream of transactions throughout the day, and a large daily batch file that reconciles and corrects the day's activity. Both need to land in the same warehouse and both matter to the analysts. Design a pipeline that handles both paths.

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
