A Smarter Way to Prepare

Stop grinding random problems. Start mastering the core patterns that unlock solutions to thousands of questions and build a reusable toolkit that works for real-world interviews.

✓
Go from confused to confident with a clear, pattern-based roadmap.
✓
Focus on the high-yield patterns that appear in 90% of interview questions.
✓
Build a deep, transferable understanding of data structures and their trade-offs.
✓
Solve new, unseen problems by recognizing the underlying patterns and their common variations.
✓
Walk into interviews with a reusable toolkit, not just a list of memorized answers.

What’s in the DSA Track

Foundations Refresher

Big‑O notation, arrays, strings, linked lists, stacks, queues, hash maps, and sets—just enough to move fast on real problems.

Core Data Structures

Trees and BSTs, heaps & priority queues, graphs (BFS/DFS), tries, and union‑find—explained with interview‑style examples.

Interview Patterns

Two‑pointers, sliding window, binary search on value, prefix sums, backtracking, greedy, and dynamic programming.

Pattern Variations & How to Spot Them

Interviewers rarely ask textbook questions. We cover common variations on core patterns so you can recognize them in unfamiliar problems and demonstrate true problem-solving ability.

Priority Problem Sets

Curated problems for each pattern and topic, designed to build confidence and mastery with high‑yield questions.

Common Pitfalls & Trade-offs

Learn the common mistakes candidates make and the subtle trade-offs interviewers look for when discussing different approaches.

DSA FAQ

How does this prepare me for problems I haven’t seen before?

Instead of memorizing solutions, you’ll master the underlying patterns and their common variations. This builds a flexible toolkit that allows you to deconstruct new, unfamiliar problems and map them to a familiar approach. Our track is designed around these core patterns, with high‑quality problems to make them second nature.

What data structures and algorithms does this actually cover?

You’ll cover arrays, strings, linked lists, stacks, queues, hash maps, trees/BSTs, heaps, graphs, tries, union‑find, plus core algorithms like BFS/DFS, binary search, sliding window, partitioning, common DP shapes (1D, 2D, subsequences), and classic greedy strategies.

Is this beginner‑friendly if I’m rusty on DSA?

Yes. We start with a quick foundations refresher and build up to more advanced patterns. As long as you’re comfortable with a programming language (Python, JavaScript, Java, etc.), you can follow along.

Can I use this alongside LeetCode?

Absolutely. Many people use SDE Prep as their roadmap and pattern guide, then reinforce those patterns on LeetCode. Instead of guessing which problems to do next, you’ll know which pattern you’re practicing and why.

How long will it take to finish the DSA track?

With 8–10 focused hours per week, most people can complete the core DSA roadmap in 4–6 weeks.
