You can think of design fundamentals as the foundational knowledge that you need for systems design interviews, just as data structures are the foundational knowledge that you need for coding interviews.

So What is SystemsExpert?

SystemsExpert is a video-based course. And it aims to help you ace the systems design interviews for FAANG-level companies.

You’ll learn extensively about systems design fundamentals like:

  • distributed computing
  • reliability engineering

  • systems architecture

And much more.

After learning the fundamentals, you’ll move on to a series of design questions.

Sounds easy enough, right?

Actually, wait a minute… No, it doesn’t.

That’s a pretty broad prompt. So you probably have some questions.

SystemsExpert provides a series of clarifying questions you should ask before proceeding with the interview.

Clarifying Questions on SystemsExpert

You’ll learn about:

🔹how to establish which parts of Netflix to design

🔹 auxiliary services to highlight

🔹necessary fictitious data needed

And beyond.

From there, you’ll follow along with the detailed mock interview video solution.

And finally, you can use the text-based solution walkthroughs to clarify key concepts in the video.

Plus, these are useful when going back to reference a particular concept or portion of the interview.

And for all of these questions, you’ll work within the…

4-Pane Integrated Workspace

When I first saw AlgoExpert’s integrated workspace, I didn’t think it could get any better.

I was wrong.

The integrated workspace on SystemsExpert has all the delicious interactive qualities of AlgoExpert’s… and then some.

Beautiful and clean integrated workspace on SystemsExpert

First off, the interface is in dark mode.

In addition, each pane is adjustable in size. And from there you can select which of the 4 panes you’d like to display:

1. Show Prompt

In this pane, you’ll:

🔹see the question

🔹read recommended clarifying questions to ask during your FAANG interview

And from there, you can take notes on your scratchpad…

2. Show Scratchpad

This is not your father’s Post-It note.

It’s an HTML-enabled scratchpad that allows you to insert headers, quotes, lists and more.

And it has an auto-save feature. So your changes are instantly saved.

Plus when you come back to a prompt, your notes will be saved and waiting for you.

3. Show Video Solution

Here is the lengthy video section of the systems design workspace.

With the mock interview you’ll hear Clément pose clarifying questions to an interviewer. And from there the interviewer will provide feedback.

This guidance enables Clément to produce a targeted solution as an interviewee.

4. Show Solution Walkthrough

Solution walkthroughs are organized and hidden by default.

These walkthroughs are meant as a reference point only after you’ve watched the video walkthrough.

Text-based solution walkthroughs are ideal to reinforce the key concepts taught in the video.


The glossary is a useful addition to the integrated work environment.

Who created SystemsExpert?

SystemsExpert was created by Clément Mihailescu (ex-Google, ex-Facebook) and Antoine Pourchet (ex-Uber).

Clément was frustrated when applying for FAANG jobs. There weren’t any decent resources available to learn and practice real-world algorithms. Or ace the technical interviews.

As a result, he and Antoine created the AlgoExpert platform.

But they didn’t stop there.

They also added a data crash course, interview tips and more.

SystemsExpert is the latest addition to the AlgoExpert platform. The course is intended to help aspiring FAANG developers ace their systems design interviews.

My only question is… what’s next?

Is SystemsExpert Worth It? Conclusion

When SystemsExpert came out, we were skeptical. How could it possibly live up to our expectations?

AlgoExpert is a tough act to follow.

But it met – and exceeded – our expectations:

🟣 With 22 modules in the Systems Design Fundamentals section, you’ll gain a thorough understanding of necessary key terms.

🟣 And the 8 mock interview questions are an ideal way to learn what to expect in the systems design portion of your FAANG interview.

🟣 In addition, the 4-pane integrated workspace is a developer’s dream. It looks sharp, it’s intuitive, and it’s easy on the eyes.

So if you’re still asking “is SystemsExpert worth it?” Think about this: Just this small investment could help land you a 6-figure salary.
