Hello guys, its no secret that System Design interview is the hardest round of FAANG interview because of its vastness and open-ended nature. While you can master problem solving and algorithmic challenges by doing LeetCode and learning patterns on sites like AlgoMonster but System Design is a different beast, it require thorough preparation.

This is especially true for mid and senior level engineers who are expected to know about System Design and that’s why it becomes increasingly important that you prepare this topic well.

And, when it comes to preparing for System Design Interviews, few names carry as much trust and authority as ByteByteGo.

System Design · Coding · Behavioral · Machine Learning Interviews

Founded by Alex Xu, the author of the best-selling System Design Interview — An Insider’s Guide, ByteByteGo has become the go-to resource for engineers aiming to crack FAANG-level interviews and master large-scale distributed systems.

But with so many new learning platforms emerging like Codemia.io, Exponent, DesignGurus, Bugfree.ai, is ByteByteGo’s System Design Course still worth it in 2025?

System Design Interview – An insider’s guide

Let’s take a deep look at what it offers, what’s new, and why it continues to stand out — especially with their 50% lifetime plan discount which offers great value and its also quite rare.

I have known them for 4 years now and I have hardly seen them offer any discount, let alone 50% discount.
