Crack the Pattern
A one-month daily batch that makes hard coding problems easy. It starts from the fundamentals so nobody is left behind, then teaches the handful of patterns behind LeetCode-style problems, each one felt on a simulation, then written and run against real tests in an in-browser editor.
What is Crack the Pattern?
A one-month daily batch that makes hard coding problems easy. It starts from the fundamentals so nobody is left behind, then teaches the handful of patterns behind LeetCode-style interview problems.
Do I need to know coding already?
No. A short Day Zero takes you from never-coded to your first list and loop, then you join the batch on the same footing. School maths and steady daily attendance are enough.
Why learn it here?
Because you feel each pattern on a simulation first, then write and run it against real tests in the browser, and finish by proving it in a live mock interview. Real practice, not lectures.
How every day feels
What you will do
- Start from zero
The first sessions take you from never-coded to your first working program.
- Read any problem
The four questions that make a scary problem clear.
- One pattern a day
The handful of patterns behind two pointers, windows, recursion, graphs, and dynamic programming.
- Feel it first
See each idea move on a simulation before you write a line.
- Solve it for real
Write your solution and run it against real tests in the browser.
- Prove it live
Finish with a live mock interview and a verifiable certificate, not a family show.
What you will be able to do
- Read any coding problem calmly, with four simple questions
- Recognise and apply the patterns behind LeetCode-style problems
- Write your solution and run it against real tests in the browser
- Prove it live in a mock interview, and explain your thinking
You walk out with a pattern playbook and a verifiable certificate.
Your journey, step by step
13 steps, from the very first day to a real skill, ending in Interview Day.
- 1Get coding
The first days take you from never-coded to your first working loop.
- 2Read any problem
The four questions that make a scary problem calm.
- 3Arrays and hashing
The shelf and the magic notebook, the two you use most.
- 4Two pointers and windows
Walk a list from both ends, and slide a window along it.
- 5Sorting and binary search
Put things in order, then find them by halving.
- 6Stacks and queues
The plate pile and the fair line, and where each one wins.
- 7Recursion
A problem that solves smaller copies of itself.
- 8Trees
Branching data, and the three ways to walk it.
- 9Graphs, wide and deep
Maps of connections, explored by breadth and by depth.
- 10Shortest paths and groups
The cheapest route, and joining things into sets (union-find).
- 11Dynamic programming
Remember what you solved so you never redo it. The one that separates offers.
- 12Greedy and the rest
When the quick choice is safe, and the last few patterns.
- Interview Day
Prove it in a live mock interview and take home your playbook and certificate.
Why this is different
Pick a time and book
24 sessions, the last is Interview Day.
24 sessions, 27 Jul to 27 Aug
On the final day each student proves it in a live mock interview, and takes home a verifiable certificate and their own pattern playbook.
How to join, in three steps
- Pick a time above and reserve a seat.
- Pay Rs 4,050 by cash or UPI at the Lab and take your GST receipt.
- Come to the Lab. We email a 6-digit code to check in.
New to coding is welcome; a short Day Zero takes you from zero to your first loop. A GST receipt is issued at the Lab; pay by cash or UPI.
Small group of 10. For students stepping into engineering, and anyone new to coding who is ready to work.
Every learner finishes with a certificate anyone can verify.
The honest bit
You leave able to read and solve interview-style problems, with a pattern playbook and a verifiable certificate. We do not promise jobs or offers; we promise the skill and the proof you build in the room, shown live on Interview Day.
"LeetCode-style" describes a kind of problem; we are not affiliated with LeetCode.
