Live Cohort · 14 Weeks · Limited Seats

Master Advanced Data Structures and Algorithms

Stop grinding at random. Start recognizing patterns.

You can solve 300 LeetCode problems and still stall on a problem you haven't seen before. This 14-week live cohort fixes that, you learn one pattern at a time in the right order, then apply it immediately through guided problem solving until spotting the approach becomes instinct.

Pattern-first curriculum · 24 modules from arrays to dynamic programming · built for coding interviews

Sound familiar?

Most engineers don't fail coding rounds because they're not smart. They fail because they practiced problems at random instead of learning the patterns in order.

"I've done 300 problems but still freeze on new ones."You solved them once, but never extracted the reusable pattern, so a fresh variant feels brand new.

"I can brute force, but I can't optimize."You get a working solution, then go blank when asked for better time or space, you don't see the right data structure.

"DP makes my brain hurt."Nobody taught you how to define the state and transition, so every DP problem feels like starting from zero.

"I run out of time in the interview."You know the idea but code it slowly and buggily, with no clean templates to lean on.

The fix isn't more problems. It's pattern-first structured practice, learn one pattern, apply it the same session, build a reusable template, repeat until recognition is automatic.

The learn → apply method

Every pattern is followed by hands-on problem solving, that's how recognition is built.

1

Learn a pattern

One core technique at a time, taught in a deliberate sequence so each new idea builds on the last. No random topic-hopping.

2

Apply it immediately

The same session, we solve representative problems live and distill a clean, reusable code template while it's fresh.

3

Combine the patterns

As your toolkit grows, problems get harder, we compose multiple patterns (two-pointer + hashing, binary search + greedy) on real interview questions.

4

Perform under pressure

Timed contests and live mock interviews in the back half, so speed, correctness, and communication all become second nature.

The 14-week roadmap

24 modules across 14 weeks, in a deliberate learning sequence. Tap any week to expand. Every week = learn the pattern, then apply it through guided problem solving. Each week also lists bonus add-on topics that round out the live time.

What learners say

"The pattern-first sequence changed everything. I stopped memorizing and started recognizing, new problems finally feel solvable."

RK
Rahul K.New grad → SDE, product company

"The learn-then-solve format forced me to actually code every session. My interview speed doubled."

AS
Ananya S.SDE-1 → SDE-2

"DP used to terrify me. The state → transition recipe made it mechanical. Cleared my loop two months later."

VT
Vikram T.Backend engineer, 4 yrs

"Graphs and tries were always my weak spots. The templates here made them routine."

Frequently asked

I'm a working professional. Can I keep up?
Yes, that's why sessions are weekend-only (Sat & Sun, 4–8 PM IST), 2 per week. They're recorded, so if you miss one you can catch up. Expect a few hours of practice between sessions, that's where the real learning happens.
What language is the course in?
The patterns and templates are language-agnostic; examples are shown in C++ and Java (the STL/Collections internals are covered for both), and you can solve in the language of your choice.
Do I need prior DSA experience?
No. We start from foundations (complexity, STL, essential math) and build up in sequence. You just need to be comfortable writing basic code.
Is it live or recorded?
100% live and interactive, you solve alongside the instructor and get real-time feedback. Recordings are provided for revision and missed sessions.
How is this different from Master Advanced System Design?
This course is about coding rounds, data structures and algorithms. Master Advanced System Design covers architecture/design rounds. Many engineers take both.
