Prep for the system design interview.
Learning how to design scalable systems will help you become a better engineer.
System design is a broad topic. There are a vast number of resources scattered throughout the web on system design principles.
This repo is an organized collection of resources to help you learn how to build systems at scale.
This is a continually updated, open source project.
Contributions are welcome!
In addition to coding interviews, system design is a required component of the technical interview process at many tech companies.
Practice common system design interview questions and compare your results with sample solutions: discussions, code, and diagrams.
Additional topics for interview prep:

Q: For interviews, do I need to know everything here?
A: No, you don't need to know everything here to prepare for the interview.
What you are asked in an interview depends on variables such as:
More experienced candidates are generally expected to know more about system design. Architects or team leads might be expected to know more than individual contributors. Top tech companies are likely to have one or more design interview rounds.
Start broad and go deeper in a few areas. It helps to know a little about various key system design topics. Adjust the following guide based on your timeline, experience, what positions you are interviewing for, and which companies you are interviewing with.

How to tackle a system design interview question.
The system design interview is an open-ended conversation. You are expected to lead it.
You can use the following steps to guide the discussion. To help solidify this process, work through the System design interview questions with solutions section using the following steps.
Gather requirements and scope the problem. Ask questions to clarify use cases and constraints. Discuss assumptions.
