Why Systems Design Matters for MLEs
Let’s be honest—technical interviews at FAANG companies are tough.
You’re expected to code, explain algorithms, and most importantly, design scalable ML systems.
That’s where many candidates get stuck.
Most people prepare with Leetcode, but system design—especially machine learning system design—is a different beast.
The good news? There’s one book that simplifies it all. It gives you real-world design frameworks, covers ML-specific challenges, and mirrors FAANG interview expectations.
Let’s dive into why it’s the best.
What’s the Book We’re Talking About?
The title says it all:
“Designing Machine Learning Systems” by Chip Huyen.
This book isn’t just theory—it’s hands-on, practical, and interview-ready.
Chip Huyen is a Stanford lecturer and AI practitioner. She’s worked at top companies like Netflix and Snorkel AI. So, she gets what FAANG interviews really ask.
What Makes This the Best Machine Learning Systems Design Book for FAANG MLE?
Here are the biggest reasons why this book outshines others:
1. Covers Real FAANG Interview Topics
FAANG interviewers love asking about:
- Building recommendation systems
- Designing real-time ML pipelines
- Managing model retraining and serving
- Scaling ML systems across millions of users
This book walks you through exactly these topics, using examples and diagrams.
2. Clear, Easy-to-Follow Language
You won’t get lost in jargon.
Chip writes in a way that even someone new to ML system design can follow. Complex ideas are broken down into simple, readable chunks.
Example: Instead of “model orchestration in distributed dataflow frameworks,” she says, “how to run your models reliably across multiple machines.”
3. Focuses on the Entire ML Lifecycle
Most books only focus on model training.
This one covers the whole pipeline, including:
- Data collection
- Feature engineering
- Model deployment
- Monitoring and feedback loops
That’s exactly what interviewers expect MLEs to know.
4. Teaches Trade-offs and Decision Making
In FAANG interviews, it’s not just what you build—it’s why you choose certain components.
This book shows you how to think about:
- Choosing batch vs streaming data
- Using offline vs online evaluation
- Deciding between different storage systems
You’ll learn to explain your choices, just like you need to in interviews.

Example Topics You’ll Find in the Book
- How to Serve ML Models at Scale
(Great for explaining latency vs throughput) - Online Learning vs Batch Updates
(Helps you talk about time-sensitive ML systems) - Feature Stores
(Common question: “How do you manage features across teams?”) - Model Monitoring and Retraining
(Critical for MLEs working in real-time apps)
Each chapter ends with key takeaways, examples, and questions. It’s like preparing for an interview while learning real-world ML architecture.

Frequently Asked Questions (FAQs)
Topic: Best Machine Learning Systems Design Book for FAANG MLE Interviews
1. What is the best machine learning systems design book for FAANG MLE interviews?
Answer:
The top recommendation is “Designing Machine Learning Systems” by Chip Huyen. It covers the entire ML lifecycle, explains system trade-offs, and mirrors the types of real-world scenarios and questions asked in FAANG interviews. It’s known for being beginner-friendly yet deeply insightful.
2. Why is system design so important in FAANG MLE interviews?
Answer:
At FAANG companies, ML Engineers do more than just train models—they design scalable systems that handle data pipelines, retraining, deployment, monitoring, and performance. Interviewers test your ability to make design choices, think through trade-offs, and communicate your system architecture clearly.
3. Does the book include real FAANG interview-style case studies?
Answer:
Yes. The book walks through step-by-step examples like building recommendation engines, real-time ML serving systems, and feature stores. These closely resemble what you might face in an actual MLE system design round at companies like Google or Amazon.
4. Is the book beginner-friendly? Do I need a lot of prior experience?
Answer:
The book is very beginner-friendly. It assumes a basic understanding of machine learning but explains complex system design concepts in clear language. Readers without production experience can still understand and apply its content.
5. Does this book help with other MLE roles outside FAANG?
