Before this: ML System Design Foundations
The round that decides seniority. The framework comes from the systems track; this module is about performing it under interview conditions — time budget, communication, handling redirection, and closing with the tradeoffs stated out loud.
Twelve full worked designs, from feed ranking to an LLM assistant, each with the follow-ups an interviewer will actually ask.
A prompt and a running clock with section budgets. Overrun on requirements and you will not reach the tradeoffs — exactly as in the real thing.
Worth 700 XP.
