Navigating the Machine Learning System Design Interview In the competitive landscape of modern software engineering, the Machine Learning (ML) System Design interview has emerged as a critical evaluation of a candidate's ability to build scalable, production-ready AI solutions. Unlike standard coding rounds, these interviews are open-ended, requiring engineers to "zoom out" and architect entire pipelines—from data ingestion to model deployment and monitoring. The Blueprint for Success

• You need practice with ambiguous, evolving requirements (the real interview skill).

2. Clarify requirements (always start here)
