Master System Design Quickly. Only the essentials to successfully pass the interview. The course is created by recruiters and engineers from FAANG.
When we conducted thousands of mock system design interviews on the Hello Interview platform, we often encountered candidates who had their interviews the next day or in a couple of days. The reality is that no one will become an expert in system design overnight. Therefore, we created the "System Design: Express Course": based on hundreds of real interviews, we identified the most common mistakes and compiled materials to help avoid them.
This course does not replace deep learning - it covers the most critical 20% that provide 80% of the effect. It is your brief, intensive, and practical path of preparation. We have focused only on what is actually tested in interviews and applied in real engineering practice.

The majority of this course is free on the original platform. We've gathered all the materials, including videos, in one place so you can learn comfortably without switching between sites.
Hello Interview is a system-design-interview preparation platform run by ex-FAANG engineers, focused entirely on the kind of high-level architectural design exercises that gate senior engineering roles at large tech companies.
The CourseFlix listing carries System Design in a Hurry — a focused, time-efficient walkthrough of the system-design-interview canon: the question categories, the back-of-the-envelope math, and the architectural-pattern vocabulary interviewers expect.
Material is paid and aimed at experienced engineers preparing for senior-level system-design interviews. For broader prep content, see CourseFlix's System Design & Architecture and Preparing for an interview category pages.

It is ideal for those needing quick preparation.
What specific tools and platforms are covered in the course?
The course includes deep dives into tools like Redis, Elasticsearch, Kafka, and DynamoDB. It also discusses API gateways and data structures for big data, such as Bloom Filters and HyperLogLog, providing a well-rounded understanding of the tools commonly used in system design.
What is not covered in this course?
The course does not aim to provide a comprehensive study of all system design topics. It focuses on essential concepts needed for interviews, so advanced topics such as distributed systems theory in depth or evolving architectures over time are not covered extensively.
How much time should I expect to commit to this course?
The lessons are designed to be concise, focusing only on the essentials. With 31 lessons, you can expect to invest time in understanding key concepts and practicing design scenarios. However, since the runtime is not specified, prospective students should plan based on the depth of topics and their familiarity with system design.
