If I wanted to get my opportunity to interview at Google or Amazon for SDE roles in the next 6-8 months…
Here’s exactly how I’d approach it (I’ve taught this to 100s of students and followed it myself to land interviews at 3+ FAANGs):
► Step 1: Learn to Code (from scratch, even if you’re from non-CS background)
I helped my sister go from zero coding knowledge (she studied Biology and Electrical Engineering) to landing a job at Microsoft.
We started with:
- A simple programming language (C++, Java, Python — pick one)
- FreeCodeCamp on YouTube for beginner-friendly lectures
- Key rule: Don’t just watch. Code along with the video line by line.
Time required: 30–40 days to get good with loops, conditions, syntax.
► Step 2: Start with DSA before jumping to development
Why?
- 90% of tech interviews in top companies focus on Data Structures & Algorithms
- You’ll need time to master it, so start early.
Start with:
- Arrays → Linked List → Stacks → Queues
- You can follow the DSA videos on my channel.
- Practice while learning is a must.
► Step 3: Follow a smart topic order
Once you’re done with basics, follow this path:
1. Searching & Sorting
2. Recursion & Backtracking
3. Greedy
4. Sliding Window & Two Pointers
5. Trees & Graphs
6. Dynamic Programming
7. Tries, Heaps, and Union Find
Make revision notes as you go — note down how you solved each question, what tricks worked, and how you optimized it.
► Step 4: Start giving contests (don’t wait till you’re “ready”)
Most students wait to “finish DSA” before attempting contests.
That’s a huge mistake.
Contests teach you:
- Time management under pressure
- Handling edge cases
- Thinking fast
Platforms: LeetCode Weekly/ Biweekly, Codeforces, AtCoder, etc.
And after every contest, do upsolving — solve the questions you couldn’t during the contest.
► Step 5: Revise smart
Create a “Revision Sheet” with 100 key problems you’ve solved and want to reattempt.
Every 2-3 weeks, pick problems randomly and solve again without seeing solutions.
This trains your recall + improves your clarity.

What is the difference between data scientist, data engineer, data analyst and business intelligence?
🧑🔬 Data Scientist
Focus: Using data to build models, make predictions, and solve complex problems.
Cleans and analyzes data
Builds machine learning models
Answers “Why is this happening?” and “What will happen next?”
Works with statistics, algorithms, and coding (Python, R)
Example: Predict which customers are likely to cancel next month
🛠️ Data Engineer
Focus: Building and maintaining the systems that move and store data.
Designs and builds data pipelines (ETL/ELT)
Manages databases, data lakes, and warehouses
Ensures data is clean, reliable, and ready for others to use
Uses tools like SQL, Airflow, Spark, and cloud platforms (AWS, Azure, GCP)
Example: Create a system that collects app data every hour and stores it in a warehouse
📊 Data Analyst
Focus: Exploring data and finding insights to answer business questions.
Pulls and visualizes data (dashboards, reports)
Answers “What happened?” or “What’s going on right now?”
Works with SQL, Excel, and tools like Tableau or Power BI
Less coding and modeling than a data scientist
Example: Analyze monthly sales and show trends by region
📈 Business Intelligence (BI) Professional
Focus: Helping teams and leadership understand data through reports and dashboards.
Designs dashboards and KPIs (key performance indicators)
Translates data into stories for non-technical users
Often overlaps with data analyst role but more focused on reporting
Tools: Power BI, Looker, Tableau, Qlik
Example: Build a dashboard showing company performance by department
🧩 Summary Table
Data Scientist - What will happen? Tools: Python, R, ML tools, predictions & models
Data Engineer - How does the data move and get stored? Tools: SQL, Spark, cloud tools, infrastructure & pipelines
Data Analyst - What happened? Tools: SQL, Excel, BI tools, reports & exploration
BI Professional - How can we see business performance clearly? Tools: Power BI, Tableau, dashboards & insights for decision-makers
🎯 In short:
Data Engineers build the roads.
Data Scientists drive smart cars to predict traffic.
Data Analysts look at traffic data to see patterns.
BI Professionals show everyone the traffic report on a screen.

🧠 How to Build Logic in Programming
👀 Understand the problem clearly
Read the question 2-3 times. Break it into small parts. Don't rush to code.
🪜 Think in steps, not code
Imagine solving it in real life. Write down the steps in simple language before jumping to code.
🧩 Start with simple problems
Practice basics like:
➡️ Find the largest of 3 numbers
➡️ Reverse a string
➡️ Check if a number is prime
🔍 Dry run your logic
Go through each line and see what it’s doing. This helps you understand how the logic flows.
📅 Practice daily
Logic building improves with consistency. The more problems you solve, the better you get.

🚀 Full-Stack Developer Roadmap (2025 Edition)
If you want to become a Full-Stack Developer, you need to master both Frontend and Backend development, along with Databases, APIs, DevOps, and Deployment.
Here’s a step-by-step roadmap to guide you:
📌 1. Learn the Fundamentals
Before diving into full-stack development, build a strong foundation.
✅ Internet Basics – How the web works, HTTP/HTTPS, DNS
✅ Basic Git & GitHub – Version control, repositories, branches
✅ Command Line (CLI) – Basic Linux/Terminal commands
📚 Resources:
🔹 GitHub Docs
🔹 HTTP Basics
📌 2. Frontend Development (Building the UI)
The frontend is what users interact with. Learn:
✅ HTML – Structure of webpages
✅ CSS – Styling, Flexbox, Grid, Responsive Design
✅ JavaScript (ES6+) – DOM Manipulation, Async/Await, Fetch API
✅ CSS Frameworks – Bootstrap, Tailwind CSS (optional)
📚 Resources:
🔹 HTML & CSS
🔹 JavaScript (JS.info)
📌 3. Frontend Frameworks (Choose One)
A frontend framework helps in building complex UI faster.
✅ React.js – Most popular, component-based, strong job market
✅ Vue.js – Lightweight, easy to learn, great for small apps
✅ Angular – Powerful but complex, used in large-scale apps
📚 Resources:
🔹 React Docs
🔹 Vue.js Docs
🔹 Angular Docs
📌 4. Backend Development (Server-Side Logic)
The backend handles data processing, authentication, and business logic.
✅ Choose a Backend Language:
JavaScript – Node.js + Express.js
Python – Django / Flask
Java – Spring Boot
PHP, Ruby, Go (Optional)

REST APIs (GET, POST, PUT, DELETE)
Authentication (JWT, OAuth, Sessions)
Middleware, Routing, Error Handling
📚 Resources:
🔹 Node.js Docs
🔹 Django Docs
📌 5. Databases & ORM (Data Storage & Management)
Databases store and manage application data. Learn:
✅ SQL Databases – MySQL, PostgreSQL (Structured data)
✅ NoSQL Databases – MongoDB, Firebase (Unstructured data)
✅ ORMs (Object Relational Mapping) – Sequelize (Node.js), SQLAlchemy (Python)
📚 Resources:
🔹 PostgreSQL Guide
🔹 MongoDB Docs
📌 6. Full-Stack Development (Combining Frontend & Backend)

Web apps must be secure and protected from attacks.
✅ Authentication Methods:
JWT (JSON Web Tokens)
OAuth (Google, Facebook Login)
Session-Based Authentication
✅ Security Best Practices:
Protect against SQL Injection, XSS, CSRF
Hash passwords with bcrypt
Use HTTPS & Helmet.js for secure headers
📚 Resources:
🔹 JWT Guide
🔹 Web Security Best Practices
📌 8. DevOps & Deployment (Hosting Your Projects)
A Full-Stack Developer should know how to deploy applications.
✅ Frontend Deployment:
Netlify, Vercel, GitHub Pages
✅ Backend Deployment:
Heroku, Render, DigitalOcean, AWS, Firebase
