DSA Home
DSA Home is not an official name of any single product or company.
It is a very popular (and very informal) way that Indian students and job-seekers call the collection of the best / most important / most repeated DSA topics + questions that almost everyone should master if they want to get placed in good product-based companies or top-tier service companies in India.
In simple words:
DSA Home ≈ “The most important, high-priority, must-do part of Data Structures & Algorithms”
It is the minimum powerful syllabus that gives you the maximum chance in interviews.
Let me explain it like a senior telling a junior in college — very honestly and in detail.
What people really mean when they say “DSA Home”
They usually mean one (or a combination) of these famous lists/sheets/resources:
- Striver’s SDE Sheet / A2Z DSA (most popular meaning of “DSA Home” in 2024–2026)
- Love Babbar’s 450 DSA Cracker
- take U forward SDE Sheet (older name, now mostly called Striver SDE Sheet)
- Arsh Goyal’s 280 Questions
- Fraz’s Sheet / Blind 75 + NeetCode 150 (more international version)
But when someone says “Bhai DSA home ho gaya?” “DSA home complete kar liya?” “DSA home ke baad kya karna chahiye?”
→ 90% of the time in Indian context they are talking about Striver’s SDE Sheet (or A2Z DSA roadmap).
What does “Striver SDE Sheet / DSA Home” actually contain?
It is roughly divided into stages/topics like this:
| Stage / Topic | Approx Questions | Difficulty | Importance (out of 10) |
|---|---|---|---|
| Step 1: Learn Basics | — | Easy | Must |
| Step 2: Learn Important Patterns | — | — | Must |
| Arrays | 25–35 | Easy–Medium | 10/10 |
| Binary Search | 15–20 | Easy–Hard | 10/10 |
| Sorting (sometimes included) | 5–10 | Easy | 8/10 |
| Linked List | 15–25 | Easy–Hard | 9/10 |
| Stack & Queue | 15–20 | Easy–Medium | 9/10 |
| Hashing (very important) | 15–25 | Easy–Hard | 10/10 |
| Two Pointers / Sliding Window | 15–25 | Medium | 9.5/10 |
| Greedy | 10–20 | Medium–Hard | 8/10 |
| Recursion & Backtracking | 15–25 | Medium–Hard | 9/10 |
| Binary Trees | 25–35 | Medium–Hard | 10/10 |
| Binary Search Tree | 10–15 | Medium | 8.5/10 |
| Heaps / Priority Queue | 10–15 | Medium–Hard | 9/10 |
| Graphs (BFS + DFS) | 25–40 | Medium–Hard | 10/10 |
| Dynamic Programming | 40–70 | Hard | 10/10 |
| Tries | 5–10 | Medium–Hard | 7.5/10 (sometimes) |
| Bit Manipulation | 8–15 | Medium | 7–8/10 |
| Segment Tree / Fenwick (optional) | 5–10 | Very Hard | 6/10 (for top companies) |
Total questions in full Striver SDE Sheet / A2Z ≈ 350–450 questions (depending on version)
Real conversation examples you hear in groups
- “Bhai DSA home ho gaya toh ab company wise karna start kar de”
- “DSA home + 100 company tagged → almost done for Amazon”
- “DSA home nahi hua toh Google, Atlassian tough hai”
- “Mera DSA home 70% hai, ab DP khatam kar raha hoon”
How long does “DSA Home” usually take?
Realistic timeline (serious 4–6 hrs/day):
| Situation | Time needed |
|---|---|
| Complete beginner (zero coding) | 9–14 months |
| Learned basic coding, but no DSA | 6–10 months |
| Already did some arrays, linked list etc. | 4–7 months |
| Already did 150–200 leetcode questions | 2.5–5 months |
Suggested realistic order to finish “DSA Home” (2025–2026 style)
- Arrays + Easy Hashing + Two Pointers
- Binary Search (very important!)
- Linked List (singly + doubly + fast-slow pointer)
- Stack + Queue + Basic Sliding Window
- Recursion (basic → medium)
- Binary Tree (traversals, height, diameter, zigzag, LCA…)
- Binary Search on Trees (BST)
- Graphs – BFS + DFS + flood fill + cycle detection
- Heaps (priority queue problems)
- Greedy (medium level)
- Dynamic Programming (this takes longest time)
After this → you are roughly “DSA Home done”
After DSA Home what next? (very common path)
| Level | What to do next |
|---|---|
| Finished DSA Home | Company wise questions (Amazon, Google, Microsoft…) |
| Want top companies | LeetCode company tagged + weekly contest |
| Want very high package | Hard graph + DP + advanced trees |
| Want Codeforces rating 1600+ | Virtual contests, AtCoder, Codeforces EDU |
| Want system design later | First finish 400–500 quality questions |
Quick cheat-sheet people use
| Topic | Minimum questions you should solve |
|---|---|
| Arrays & Hashing | 40–50 |
| Binary Search | 25–30 |
| Linked List | 20–25 |
| Stack & Queue | 20 |
| Sliding Window | 15–20 |
| Trees (Binary + BST) | 50–60 |
| Graphs | 40–50 |
| Heap | 15–20 |
| DP | 60–100 (most important) |
| Greedy + Backtracking | 25–35 |
So in short:
“DSA Home” = the core, most important, interview-cracking portion of Data Structures and Algorithms that almost every serious student tries to finish before starting heavy company-specific or contest practice.
If someone asks you “DSA home kiya?” they are basically asking: “Have you done the important part of DSA that actually gets you jobs?”
Do you want me to explain any specific topic from “DSA Home” in detail (like Sliding Window, DP states, Graph BFS vs DFS, Binary Search on answer etc.)? Just tell the topic — I’ll teach like a friend sitting next to you. 😄
