Hello guys, if you are preparing for technical interviews for Software Engineering job then you may be aware of the importance of Software Design or System design topic.
It is one of the most important but at the same time very tough topic to master and many programmers even experienced developer struggle to solve System design problems during interview, 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 programming job interview and looking for best System design and Software design resources then you are at the right place.
Earlier, I have shared best System Design Books, System Design Questions, System Design Cheat Sheets, and best Places to learn System Design and in this article, I am going to share best System Design Interview courses from Udemy, one of my favorite place to learn programming and technical stuff.
A couple of years ago, you can hardly find any decent System design course online like on Udemy, the ones which are available hardly touch the topic which matters like 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 great and you need to be careful while choosing the right course for you.
A lot of my readers asked me about 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 those interview and has experience from both side of table, as a candidate and interviewer. For example, Frank Kane, whose System Design interview course is one of the best on Udemy is an ex Amazon hiring manager.

If you like to learn from multiple resources then you can also join all of them but make sure you use them judicially as you will not have enough time to go through every course. I generally make one course as corner stone and the keep referring others to solidify different topics.
If I connect to one instructor better than I stick with that course more because when you connect to the instructor you tend to learn better, faster and in-depth.
You can also watch previews of these courses to see if you are connecting with instructor before joining these courses to save your time and money.
If you cannot withstand previews then you won’t enjoy the course either. So make sure you watch the preview System design lesson to see if the course deserve your time and money.
