This course by Design Gurus has helped 150k+ subscribers to crack their system design interview (SDI).

System design questions have become a standard part of the software engineering interview process. Performance in these interviews reflects upon your ability to work with complex systems and translates into the position and salary the interviewing company offers you. Unfortunately, most engineers struggle with SDI, partly because of their lack of experience in developing large-scale systems and partly because of the unstructured nature of SDIs. Even engineers who've some experience building such systems aren't comfortable with these interviews, mainly due to the open-ended nature of design problems that don't have a standard answer.

This course is a complete guide to master SDIs. It is created by hiring managers who've been working at Google, Facebook, Microsoft, and Amazon. We've carefully chosen a set of questions that have been repeatedly asked at top companies.

I found your site 24 hours before interviewing at Amazon. It was my 2nd try with Amazon, and I knew that one of the problems they had with me the first time was that I didn’t really know how to work through the system design phase of the interview. I spent the day reading the basics section and then read through all of the problems. I not only got an offer from Amazon, the group the guy was from asked me to sign on with them. Relative to the salary offer that followed, the cost of this course was without question the best investment in the history of the universe!

Great course. After going through it, I think, the real value is in the system design problems. For that alone, it’s worth it, even for an experienced professional. The course focuses on laying down the thought process for attacking a system design problem. Interviewers are looking for a collaborative communication and demonstration of the problem-solving process; that organization of thought alone is worth buying the course.

This course contains some of the most thoughtful and clear explanations for common system design interview questions (e.g. "design bit.ly", "design Yelp") that I have seen anywhere. While good answers to some questions can be found elsewhere (Quora, YouTube, highscalability.com, etc), this is the most complete resource for system design Q&A that I found. It helped me feel confident in my interviews more than any other resource and was well worth the cost.

Thanks for a great resource! You guys are a lifesaver. I struggled a lot in design interviews, and this course gave me an organized process to handle a design problem. Please keep adding more questions.
