Define functional (what the system does) and non-functional requirements (latency, throughput, availability).
Ingests and transforms real-time user action logs (clicks, views) into real-time model features. 🚀 Pro-Tips for Acing the Interview
If you prefer structured, offline reading, several high-quality PDFs and books dominate the MLSD interview prep landscape. You can frequently find community-contributed summaries, cheat sheets, and official chapters of these guides hosted directly on GitHub.
Clone this to understand how to draw "High-Level Design" diagrams. ML interviews require you to draw a pipeline from Kafka -> Spark -> Feature Store -> Model Server.
Production models degrade over time. You must design a system to catch this. Machine Learning System Design Interview Pdf Github
Use Canary deployments or Shadow deployments to test the model on a small percentage of live traffic.
repositories and PDF guides that offer structured frameworks and real-world case studies. Top GitHub Repositories for ML System Design
Note: For each example, list key requirements, high-level diagram, data flow, feature store plan, model choice, training infra, serving approach, monitoring, and rollout strategy.
ML systems are moving to real-time. This repo explains exactly how to do feature engineering on streaming data (tumbling windows, sliding windows). You need this for "real-time fraud detection" questions. Define functional (what the system does) and non-functional

This is the current gold standard. Although the physical book is paid, summarized PDF notes and flashcards are widely referenced.
