How to prepare for the system design interview question
The best way to prepare for the system design interview question is to practice as much as possible. There is no one-size-fits-all solution for any system design problem, so you need to expose yourself to different types of questions and scenarios and learn from them. Here are some tips on how to practice effectively:
Review the fundamental concepts and patterns in system design. You should have a solid understanding of the basic principles and components of any system, such as data structures, algorithms, databases, networks, concurrency, caching, load balancing, sharding, replication, consistency, availability, fault tolerance, security and so on. You should also be familiar with some common patterns and techniques that are used to solve system design problems, such as PACELC theorem, heartbeat, AJAX polling, HTTP long-polling, WebSockets, server-sent events (SSEs) and so on.
Read some books or articles on system design. There are some books or articles that can help you learn more about system design in depth and breadth. For example, you can read [PDF] System Design Interview: An Insider's Guide by Alex Xu or [PDF] Designing Data-Intensive Applications by Martin Kleppmann. These books or articles can provide you with some real-world examples and insights on how to design different systems.
Watch some videos or courses on system design. There are some videos or courses that can help you learn more about system design in a visual and interactive way. For example, you can watch System Design Interview An Insider's Guide by Success in Tech or Grokking the System Design Interview by Educative. These videos or courses can provide you with some step-by-step guidance and tips on how to tackle different system design problems.
Solve some mock system design interview questions. There are some websites or platforms that can help you practice your system design skills with mock questions and feedback. For example, you can use Interviewing.io or Pramp to get matched with other candidates or mentors and solve real system design interview questions live. You can also use LeetCode or AlgoExpert to get access to hundreds of system design interview questions and solutions.
Review some existing systems or architectures. There are some websites or blogs that can help you learn more about how some popular systems or architectures work behind the scenes. For example, you can use High Scalability or The Architecture of Open Source Applications to get access to detailed explanations and diagrams of various systems or architectures.
What are the fundamental concepts and patterns in system design
Before you start solving any system design interview question, you should have a solid understanding of the fundamental concepts and patterns in system design. These concepts and patterns are the building blocks of any system and can help you make better decisions and trade-offs when designing a system. Here are some of the most important concepts and patterns that you should know:
PACELC theorem: This is a theorem that states that in any distributed system that may experience network partitions (P), one has to choose between availability (A) and consistency (C), as in the CAP theorem; but else (E), even when the system is running normally in the absence of partitions (L), one has to choose between latency (L) and consistency (C). This theorem helps you understand the trade-offs between different consistency models in distributed systems.
Heartbeat: This is a technique that involves sending periodic messages between nodes in a distributed system to check their liveness and status. This technique helps you detect failures and maintain fault tolerance in distributed systems.
AJAX polling: This is a technique that involves sending repeated requests from a client to a server at regular intervals to get updated data from the server. This technique helps you implement real-time updates in web applications.
HTTP long-polling: This is a technique that involves keeping an HTTP connection open until new data is available from the server, then sending it to the client and closing the connection. This technique helps you reduce network overhead and improve performance in web applications.
WebSockets: This is a protocol that enables bidirectional communication between a client and a server over a single TCP connection. This protocol helps you implement full-duplex communication and real-time updates in web applications.
Server-sent events (SSEs): This is a technology that enables unidirectional communication from a server to a client over an HTTP connection. This technology helps you push data from the server to the client without requiring the client to request it.
