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.

SQL Basics for Data Analysts SQL (Structured Query Language) is used to retrieve, manipulate, and analyze data stored in databases. 1️⃣ Understanding Databases & Tables Databases store structured data in tables. Tables contain rows (records) and columns (fields). Each column has a specific data type (INTEGER, VARCHAR, DATE, etc.). 2️⃣ Basic SQL Commands Let's start with some fundamental queries: 🔹 SELECT – Retrieve Data

SELECT * FROM employees; -- Fetch all columns from 'employees' table SELECT name, salary FROM employees; -- Fetch specific columns 

🔹 WHERE – Filter Data

SELECT * FROM employees WHERE department = 'Sales'; -- Filter by department SELECT * FROM employees WHERE salary > 50000; -- Filter by salary 

🔹 ORDER BY – Sort Data

SELECT * FROM employees ORDER BY salary DESC; -- Sort by salary (highest first) SELECT name, hire_date FROM employees ORDER BY hire_date ASC; -- Sort by hire date (oldest first) 

🔹 LIMIT – Restrict Number of Results

SELECT * FROM employees LIMIT 5; -- Fetch only 5 rows SELECT * FROM employees WHERE department = 'HR' LIMIT 10; -- Fetch first 10 HR employees 

🔹 DISTINCT – Remove Duplicates

SELECT DISTINCT department FROM employees; -- Show unique departments 

Mini Task for You: Try to write an SQL query to fetch the top 3 highest-paid employees from an "employees" table.
