Hello folks, if you are preparing for technical interviews for a Software Engineering job, you may know the importance of Software Design or System design topic.
It is one of the most important but, at the same time, very tough topics to master, and many programmers, even experienced developers, struggle to solve System design problems during interviews, particularly while interviewing with top tech companies like Google, Meta, Amazon, Apple, Microsoft, Netflix etc, popularly known as FAANG.
If you are also preparing for a programming job interview and looking for the best System design and Software design resources, you are at the right place.
I have shared the best System Design Books, System Design Questions, System Design Cheat Sheets, and Best Places to learn System Design. In this article, I will share the best System Design Interview courses from Udemy, one of my favorite places to learn programming and technical stuff.
A couple of years ago, you could hardly find any decent System design courses online like on Udemy; the available ones barely touched the topic of Scalability, resiliency, and flexibility, but things have changed since.
Nowadays, there are so many System design courses you can find on Udemy, but again, not everything is excellent, and you need to be careful while choosing the right path for you.
Many of my readers asked me which System design course to join on Udemy to prepare for programming interviews, so I decided to share my recommendations.
The list includes System design interview courses from those who have been part of that interview and has experience from both sides of the table as a candidate and interviewer. For example, Frank Kane, an ex-Amazon hiring manager, whose System Design interview course is one of the best on Udemy.
You can join one or more of these System design courses to prepare for your System design interview. One of the best things about Udemy is that it’s very affordable, and now is probably the best time as they are running the biggest sale of the season where all the top courses are available for almost 85% discount; you can join a couple of excellent methods with a price of one.
Anyway, let’s jump into the best System design courses from ByteByteGo, Design Guru, Exponent, Educative, Codemia.io, Bugfree.ai and Udemy which have many great System design courses and other popular online platforms and find the one right for you.
Without wasting any more time, here is a list of the best online courses you can join on Udemy to learn about essential System design concepts and prepare for System design interviews in 2026.

This is one of the most recent and up-to-date courses on System Design, created by ZTM Academy and Yihua, one of their lead instructor and System design expert.
What I liked about this course is their chapter on Scalability, which explained the difference between horizontal and vertical scaling of Systems and the challenges distributed systems face.
What sets this course apart from other system design courses is its emphasis on seeing and executing the bigger picture.
It goes beyond low-level coding and encourages students to understand the broader system they are a part of, fostering a deeper comprehension of the “why” behind their work.
By providing a problem-solving framework and practical knowledge gained from Yihua’s industry experience, the course empowers students to become better problem-solvers and programmers.

You would need a ZTM membership to watch this course, which costs around $39 per month and provides access to many super engaging and practical courses like this Python course. You can also use my code FRIENDS10 to get a 10% discount on any subscription.
That’s all about the best Software Design and System Design Interview course for programmers and developers in 2026. To be honest these are the top resources and its hard to leave anyone out but considering the time I recommend you to join only one or two of these courses as the price is not a problem.
You can join all their bits if you like learning from multiple resources. Make sure you use them j, judicially, as you will not have enough time to go through every course. I generally make one course as a corner stone and refer others to solidify different topics.
If I connect to one instructor better, I stick with that course more because when you connect to the instructor you tend to learn faster. Then, watch previews of these courses to see if you are connecting with the instructor before joining these courses to save you time and money.
If you cannot withstand previews, you won’t enjoy the course either. So watch the preview System design lesson to see if the course deserves your time and money.
