Why this roadmap works
The roadmap overview describes 12 phases grouped into five learning sections. This gives you a sequence to follow, while still letting you jump to a topic you already understand.
- A 12-phase learning path grouped into five sections, as shown in the roadmap overview
- ★ High-priority interview questions clearly flagged
- Language-agnostic — works with JS, Java, Python, C++
- Downloadable TXT access guide delivered after payment confirmation

3 difficulty levels
Fundamentals
Build the basics right. Loop patterns, array operations, string methods, simple hashing.
Common coding rounds
Practice common patterns such as sliding windows, linked lists, binary search, and recursion.
Advanced problem-solving
Explore advanced problem-solving with backtracking, graphs, dynamic programming, and bit manipulation.
High-priority interview questions are marked with ★ throughout all three levels, so you can spot the must-know problems instantly.
Who is this for?
CS / IT students
Building a strong foundation before campus placements or internship interviews.
Self-taught developers
No CS degree but want to crack coding interviews at product companies.
Working engineers
Switching from service-based to product companies and need structured DSA prep.
Competitive programmers
Looking for complete coverage of algorithmic topics beyond easy arrays.
Bootcamp graduates
You know how to build — now you need to get past the whiteboard round.
Anyone starting fresh
Zero background. Start at Phase 1 and work through at your own pace.
Frequently asked questions
Who is this roadmap for?
Anyone starting from zero or trying to get interview-ready. It works for CS students, self-taught developers, and working engineers switching into product companies.
Which programming languages are covered?
The roadmap is language-agnostic — all problems work in JavaScript, Java, C++, and Python. You pick your language.
How is this different from LeetCode's problem list?
This roadmap proposes a topic sequence across five sections. It is a study guide, not an interactive coding platform or a replacement for solving problems in your preferred practice environment.
How do I get access after purchasing?
After Dodo Payments confirms the order, the TXT access guide is sent to your account email and appears in Purchases. It contains the roadmap document link; Google may ask you to request access according to the document owner's sharing settings.
Is this a one-time purchase?
This is a one-time payment for the downloadable TXT access guide. Access to the linked Google Doc follows the document owner's sharing settings and any updates made to that document.
What if I'm already intermediate — should I skip ahead?
You can. Each section is self-contained. If you're comfortable with arrays and strings, jump straight to Problem-solving Patterns (Phase 5).
Does it cover system design or behavioral rounds?
No. This roadmap is focused entirely on data structures and algorithms — the coding round portion of technical interviews.
Can I use this for competitive programming as well?
Absolutely. The coverage through graphs, DP, and bit manipulation covers the core competitive programming topics.
