Interview Prompt
A single consumer can't keep up with a 16-partition topic and lag is growing. Naively running two copies makes both read everything and double-process. Design consumption that scales horizontally without double-processing or losing offsets on restart.

- Ask clarifying questions to the AI interviewer
- Write your pipeline design solution with real code execution
- Get instant feedback and a hire/no-hire decision
