"Pradeep's LLD and HLD sessions in the CohortbyPradeep were practical, structured, and incredibly valuable. They strengthened my system design skills and played an important role in my interview preparation. Happy to share that I recently secured a Principal Solution Architect role at Amgen. Thanks, Pradeep." — Ajay 🚀

"The 5-step framework alone was worth it. I used it in my Rubrik interview and cleared the LLD round on the first attempt." — Bhavy Ramani, SDE-2, Rubrik 🚀
Join the Next Batch →The biggest difference between an average engineer and someone who clears top product company LLD & HLD interviews isn't knowledge—it's having a proven framework to think, design, and communicate under pressure.
Two structured live cohort — pick the one that fits your interview goal.
Build a rock-solid System Design foundation and master the concepts required to confidently design real-world systems like YouTube, Twitter, Payment Gateways, and many more. Along with strong conceptual fundamentals, we'll cover 15+ of the most important System Design interview questions and conduct mock interviews to help you think, communicate, and perform like you're in an actual interview.
Master object-oriented design, design patterns, and 15+ real interview problems — coded live.
I'm a Senior Backend Engineer with 5+ years of experience building large-scale distributed systems — and a graduate from IIIT Delhi. I've worked at product-based companies like NetApp and Qualcomm, shipping systems that handle real-world scale and reliability challenges.
My backend work spans distributed systems — designing fault-tolerant services, working with consensus, concurrency primitives, and high-throughput data pipelines — the same depth interviewers probe in both LLD and HLD rounds at senior levels.
I've personally cleared LLD and HLD rounds at top product companies — and beyond that, I've taught 500+ engineers: SDE-1s, SDE-2s, Staff Engineers, and Cloud Architects across cohorts. I've helped 100+ students land offers at companies like Rubrik, Swiggy, Razorpay, and FAANG.
What I've seen consistently: engineers don't fail system design rounds because they can't code or think. They fail because nobody ever gave them a repeatable structure to clarify, design, and communicate under pressure — whether it's LLD or HLD.
"Engineers don't fail design interviews because they lack knowledge. They fail because they don't have a clear framework to think, communicate, and defend decisions under pressure."
These cohorts are the distillation of everything I wish I had — and everything I've refined across 500+ students preparing for both LLD and HLD rounds.

💡 One HLD round cleared = ₹10–30L salary jump. This course pays for itself on the first day of a better offer.
Every product company above SDE-2 uses system design to filter candidates. This is where offers are won or lost.
Google, Amazon, Flipkart, Swiggy, Razorpay, Confluent — all of them use HLD to filter SDE-2 and above. You cannot get to offer stage without clearing this round.
Most engineers try to memorise system designs. That doesn't work — interviews throw curveballs. You'll learn the clarify → estimate → design → deep dive framework so you can crack any problem cold.
YouTube, Twitter feed, Payment gateway, URL Shortener — the exact problems companies ask. You'll watch Pradeep design them live, think through trade-offs, and defend decisions the way interviewers expect.
Distributed transactions, Saga pattern, Circuit breakers, Sharding internals, CAP theorem applied — the depth interviewers actually probe at senior levels.
Clearing HLD unlocks SDE-2, SDE-3, and Staff roles. The salary jump from cracking this one round often covers 10× the course fee in the first month.

"The way you have adopted to make us understand seems to be the best way."
"The deep dives into SOLID principles and Design Patterns using real-world examples like a Parking Lot and Elevator System made complex concepts feel intuitive."
"I'm having a great learning experience. Your structured and well-organized approach to explaining LLD makes complex concepts easy to understand and brings great clarity."
"Complex design principles were explained clearly with practical examples. I now feel much more confident writing clean, scalable, and maintainable code."
"Very good and recommended to everyone who place importance on knowledge over money in the IT industry."
"The structure of the program is well designed, and the sessions are interactive and engaging, which makes it easy to stay focused and involved."
"Pradeep is very approachable and always easy to reach out to for any doubts or clarifications, which creates a comfortable and supportive learning environment."

This course is for working professionals (SDE-1, SDE-2 and beyond), final-year students, and freshers who are preparing to crack LLD rounds at product-based companies. You should know basic OOP and be comfortable writing code in any language.
No. The course starts from first principles — SOLID, OOP, basic patterns — and builds up to complex problems. Beginners are welcome, but you should know how to write a class and basic OOP.
I code live in Java, but LLD itself is language-independent — the design patterns, principles, and frameworks carry over to any OOP language. Code walkthroughs in other languages (Python, C++, Golang, JS) will also be provided.
All sessions are recorded and uploaded within 24 hours. You get lifetime access to every recording, so missing a session won't affect your learning.
Live sessions run on Zoom. Recordings and resources are shared via a private community portal.
Yes — every enrolled student gets a dedicated 1-on-1 mock interview with peers and Pradeep will be monitoring those sessions and feedback will be provided.
Yes — we offer a full refund if you request it within the first 3 classes. If the content, teaching style, or pace doesn't meet your expectations after attending the initial sessions, just reach out and we'll process your refund — no questions asked. After the 3rd class, refunds are not available.
One salary increment from a better job offer often pays for this course 100x over. But more importantly: the confidence and structured approach you build here compounds across every technical interview you take in your career.
This course is for working professionals targeting SDE-2, SDE-3, and Staff Engineer roles. If you're preparing for system design rounds at companies like Google, Amazon, Flipkart, Swiggy, Razorpay, or any product-based company — this is for you. You should be comfortable writing code and have basic awareness of how web systems work.
No prior HLD knowledge is required. The course starts from fundamentals — CAP theorem, estimation, SQL vs NoSQL — and progressively builds to designing real-world systems like YouTube and Payment gateways. But you should know basic backend concepts like APIs and databases.
YouTube videos give you polished solutions. Interviews are not polished — they're ambiguous, follow-up heavy, and require real-time reasoning. This course teaches you the thinking process: how to clarify, estimate, design, and defend decisions under pressure — the way top interviewers actually evaluate candidates.
URL Shortener, Twitter/Instagram Feed, YouTube/Netflix, WhatsApp Messaging, Uber, Rate Limiter, Key-Value Store, Notification System, Payment Gateway, Distributed Task Scheduler, Search Autocomplete, Web Crawler, Leaderboard, and more — 18+ real HLD problems in total.
All sessions are recorded and uploaded within 24 hours. You get lifetime access to every recording — missing a class won't set you back.
Yes — Week 8 is fully dedicated to mock HLD interviews. You'll get 2–3 full mock sessions with detailed feedback on your approach, communication, and trade-off decisions.
HLD Cohort runs on weekends — Saturday & Sunday, 4–6 PM IST. Batch starts 1st August. Sessions are 2 hours each, packed with live system design and Q&A.
Yes — for the HLD cohort, we offer a full refund if you request it within the first 3 classes. If the content, teaching style, or pace doesn't meet your expectations after attending the initial sessions, just reach out and we'll process your refund — no questions asked. After the 3rd class, refunds are not available.
Absolutely — and we recommend it. LLD and HLD are both tested at most product companies. Doing both gives you complete interview readiness across all design rounds.
