📌 Why FAANG Interviews Are Different

FAANG interviews go beyond coding—they evaluate problem-solving skills, system thinking, communication, and cultural fit. Here's what typically awaits candidates:

• Online coding assessments (OAs)

• Technical phone screens

• Onsite rounds (3–5 interviews)

• Behavioral and bar-raiser interviews

• System design (for mid to senior roles)

You’ll be tested not only on your technical knowledge, but on how you think, communicate, and scale your solutions.

🧩 Step 2: Master Data Structures & Algorithms (DSA)

This is the foundation of most technical interviews. Key topics include:

• Arrays, Strings

• Hash Maps & Sets

• Linked Lists, Trees, Graphs

• Recursion & Backtracking

• Sliding Window & Two Pointers

• Greedy & Dynamic Programming

• Sorting & Binary Search

• Heaps, Stacks, Queues

Suggested Plan:

• Practice 2–3 problems daily on LeetCode or HackerRank

• Solve at least 300 questions in varying difficulty

• Focus on company-specific tags (e.g., “Amazon,” “Google” on LeetCode)

• CAP theorem, consistency models

• Microservices, message queues

• Database design (SQL & NoSQL)

• Scalability and fault tolerance

• RESTful APIs, rate limiting, authentication

Resources:

• Grokking the System Design Interview (Educative.io)

• YouTube channels like Gaurav Sen & Tech Dummies

• System Design Primer GitHub repo

Practice Scenarios:

• Design Twitter, Uber, Dropbox, WhatsApp, Instagram
