From scrolling System Design reels to designing systems yourself.

The HLD Live Cohort by Dhruv has been a great learning experience! What I particularly appreciate about Dhruv’s teaching is that he explains everything from first principles and focuses on the why behind every architectural decision, rather than just explaining what a component does.

The cohort started with the fundamentals and gradually progressed towards designing complex systems, helping us understand how to structure a design, choose the right components, and evaluate different architectural approaches. Another thing that makes this cohort stand out is the interview-focused guidance. Dhruv explains how to approach HLD questions in interviews, present our designs effectively, make the right trade-offs, and avoid common mistakes.

The live teaching format is another big advantage. We can ask questions, clarify doubts, and get explanations in real time. The supporting notes deserve a special mention, too! Written in Hinglish, they feel just like notes you’d borrow from a friend in college, easy to relate to, yet detailed enough to revisit concepts in depth.

One of the standout features of this cohort is its simulators. They are truly amazing and make learning much more engaging by allowing us to see how different architectural concepts work through interactive 3D visualizations. The diagrams are equally impressive, making complex concepts, component interactions, and different architectural scenarios much easier to visualize and understand.

Overall, this cohort goes beyond simply teaching system design concepts. It helps build the understanding, practical thinking, and interview skills needed to apply those concepts confidently. Highly recommended for anyone looking to strengthen their HLD and system design skills!

I’m currently part of Dhruv’s HLD cohort, and it’s been an amazing learning experience so far!

What really stands out is the depth and clarity with which Dhruv covers every concept, starting from the absolute basics and gradually progressing to advanced system design topics. He makes even complex concepts easy to understand, and the sessions are always engaging, interactive, and thought-provoking.

The notes are exceptionally well-structured and detailed, making them a fantastic resource for revisiting concepts. The simulators are another huge highlight, helping bridge the gap between theoretical knowledge and practical application.

It’s evident how much thought and effort goes into designing the entire learning experience. I genuinely look forward to every session and would highly recommend this cohort to anyone looking to build a strong foundation and gain deeper expertise in High-Level Design.

Definitely one of the most valuable learning experiences I’ve had!

Absolutely worth the time and money!

Dhruv explains every concept in depth, and the notes he has curated are insightful, well-structured, and great for revisiting concepts later. The visualisations accompanying most topics make the learning experience even better, allowing us to experiment with concepts and understand their practical applications beyond just theory.

What I particularly appreciate is Dhruv’s patience in answering every question. Being part of a cohort also adds immense value, as you get to learn from others’ questions, perspectives, and thought processes.

A solid 10/10 recommendation for anyone looking to upskill, strengthen their fundamentals, or revisit concepts they already know. If you’re investing in learning HLD, this cohort is absolutely worth it!

We’ve just gotten started with the HLD, and I already know I won’t need to look for any other system design resource.

If learning system design is what anyone is looking for, I’d strongly recommend joining without a second thought. There are plenty of resources out there, but once you attend a few sessions, you’ll see the difference for yourself.

I’ve tried learning system design before, but the way concepts are explained here, along with the resources provided, is top-notch. 100% recommended! 🙌

Enrolling in the DhruvTechBytes System Design Cohort has been an absolute game-changer for my preparation.

Prior to joining this cohort, I found myself constantly scrolling through random blogs, videos, and documentation trying to piece system design concepts together - always second-guessing whether I was missing critical fundamentals.

Dhruv’s cohort solved that problem completely. The depth of knowledge and real-world expertise he brings to the live sessions is exceptional. What truly sets this program apart is having everything curated in one cohesive place: highly interactive live classes, comprehensive notes, intuitive Excalidraw diagrams, and visual architectures.

It eliminates the guesswork and builds genuine conceptual confidence. A fantastic initiative - truly grateful for the opportunity to learn from you! ✌🏻

I’ve been taking Dhruv’s HLD Live Cohort, and it’s honestly one of the best system design courses I’ve done. Instead of just showing you where to drop components on a diagram, Dhruv focuses on first principles and explains the actual “why” behind every trade-off. The progression from basic building blocks to complex distributed systems is really well thought out, and the interview-focused tips on how to present designs and steer discussions are super practical.

The live Q&A keeps things interactive, and the study notes read like solid notes you’d grab from a college friend - super easy to review without losing any technical depth.
