System design interviews can be daunting due to their complexity and the vast knowledge required to excel. Whether you’re a recent graduate or a seasoned engineer, preparing for these interviews necessitates a well-thought-out strategy and access to the right resources. In this article, I’ll guide you to navigate the system design landscape and equip you to succeed in your upcoming interviews.

Start with the Basics

“Web Scalability for Startup Engineers” by Artur Ejsmont — This book is recommended as a starting point for beginners in system design.

“Designing Data-Intensive Applications” by Martin Kleppmann is described as a more in-depth resource for those with a basic understanding of system design.

It’s essential to establish a strong foundation before delving too deep into a subject. For beginners, “Web Scalability for Startup Engineers” is an excellent resource. It covers the basics and prepares you for more advanced concepts. After mastering the fundamentals, “Designing Data-Intensive Applications” by Martin Kleppmann will guide you further into data systems.

Microservices and Domain-Driven Design

“Building Microservices” by Sam Newman — Focuses on microservices architecture and its implications in system design.

Once you are familiar with the fundamentals, the next step is to explore the intricacies of the microservices architectural style through “Building Microservices.” To gain a deeper understanding of practical patterns and design principles, “Microservices Patterns and Best Practices” is an excellent resource. Lastly, for those who wish to understand the philosophy behind system architecture, “Domain-Driven Design” is a valuable read.

API Design and gRPC

“RESTful Web APIs” by Leonard Richardson, Mike Amundsen, and Sam Ruby provides a comprehensive guide to developing web-based APIs that adhere to the REST architectural style.

In the present world, APIs serve as the main connecting point of the internet. If you intend to design effective APIs, a good starting point would be to refer to “RESTful Web APIs” by Leonard Richardson and his colleagues. Moreover, if you are exploring the Remote Procedure Call (RPC) genre, particularly gRPC, then “gRPC: Up and Running” is a comprehensive guide.

Preparing for the Interview

“System Design Interview — An Insider’s Guide” by Alex Xu is an essential book for those preparing for challenging system design interviews.

It offers a comprehensive look at the strategies and thought processes required to navigate these complex discussions. Although it is one of many resources candidates will need, the book is tailored to equip them with the means to dissect and approach real interview questions. The book blends technical knowledge with the all-important communicative skills, preparing candidates to think on their feet and articulate clear and effective system design solutions. Xu’s guide demystifies the interview experience, providing a rich set of examples and insights to help candidates prepare for the interview process.

Domain-Specific Knowledge

Enhance your knowledge in your domain with books such as “Kafka: The Definitive Guide” for Distributed Messaging and “Cassandra: The Definitive Guide” for understanding wide-column stores. “Designing Event-Driven Systems” is crucial for grasping event sourcing and services using Kafka.

General Product Design

Pay attention to product design in system design. Books like “The Design of Everyday Things” and “Hooked: How to Build Habit-Forming Products” teach user-centric design principles, which are increasingly crucial in system design.

Online Resources

The internet is a goldmine of information. You can watch tech conference talks, follow YouTube channels such as Gaurav Sen’s System Design Interview and read engineering blogs from companies like Uber, Netflix, and LinkedIn.
