Introduction:

Let’s face it: preparing for FAANG interviews can feel overwhelming.

You open YouTube, and there are hundreds of videos telling you to “grind 300 LeetCode problems.” Then you browse Reddit, and everyone seems to have a different strategy. One person says focus on dynamic programming. Another says behavioral interviews are the real test. And someone else just cleared Google after eight failed attempts.

All this noise leads to one common feeling: confusion.

If you're tired of bouncing between resources, wondering if you're doing enough—or doing it right—this blog will help you reset. Let’s cut through the clutter and build a FAANG interview prep plan that’s clear, focused, and actually works.



Step 1: Know What You're Preparing For


Before anything else, understand this: each FAANG interview follows a predictable structure. While the process might vary slightly between companies or roles, here’s the general format:

  • Online assessment (optional, usually for new grads)

  • Technical phone screen (DSA-focused)

  • Onsite or virtual onsite interviews (2–5 rounds)

  • Behavioral interviews

  • System design (for mid to senior roles)


So your FAANG interview prep should be divided into three core buckets:

  1. Coding and problem-solving

  2. Behavioral and communication skills

  3. System design (if applicable)


If your prep plan doesn’t address all three, you’re not fully ready.



Step 2: Build a Strong DSA Foundation


This is the non-negotiable part of FAANG interviews. Whether you’re interviewing for a backend, frontend, data, or even ML role—coding rounds are where most candidates are filtered out.

Focus on understanding the following topics inside and out:

  • Arrays & Strings

  • Hash Maps & Sets

  • Recursion & Backtracking

  • Stacks & Queues

  • Trees & Graphs (DFS, BFS, traversal)

  • Sliding Window & Two Pointers

  • Binary Search & Sorting

  • Dynamic Programming

  • Heaps and Priority Queues


But here’s the catch: solving hundreds of problems won’t help unless you identify patterns.

In your FAANG interview prep, make it a point to:

  • Solve 2–3 problems daily, not 10 in one sitting

  • Spend time rewriting solutions cleanly

  • Practice explaining your approach out loud

  • Focus more on problems you get wrong than the ones you get right


The quality of your understanding matters more than the volume of problems solved.



Step 3: Practice With Realistic Conditions


This is where most candidates fall short. Solving problems on your own is one thing. Solving them with a time limit, no IDE, while explaining out loud is something else entirely.

Simulating the pressure of a real interview builds confidence.

During your FAANG interview prep:

  • Use a plain text editor or whiteboard

  • Set a timer (30–45 minutes per problem)

  • Don’t rush—focus on clarity over speed

  • Regularly do mock interviews with friends or online platforms (like Pramp or Interviewing.io)


Even if you're not perfect, the experience itself will train your brain to think faster and speak clearly.



Step 4: Take Behavioral Interviews Seriously


It’s easy to think, “I’ll just wing it.” But behavioral interviews are often the deciding factor between two technically strong candidates.

These rounds assess:

  • Ownership and leadership

  • Communication style

  • Problem-solving approach

  • Alignment with company culture


In your FAANG interview prep, prepare 8–10 stories using the STAR method:

  • Situation: What was going on?

  • Task: What were you supposed to do?

  • Action: What did you actually do?

  • Result: What happened in the end?


Have stories that highlight:

  • Overcoming failure

  • Resolving conflict

  • Leading a project

  • Making trade-offs

  • Learning quickly under pressure


Practice delivering your stories conversationally. You don’t want to sound rehearsed—but you do want to sound confident and clear.



Step 5: Learn System Design Basics


If you’re aiming for an L4+ role or higher (or even some entry-level roles at Google and Meta), system design will be part of your interview.

Don’t let it intimidate you. Start with the basics:

  • Understand scalability, availability, and reliability

  • Learn about API gateways, caching, load balancing

  • Understand database choices (SQL vs NoSQL)

  • Practice designing common systems like:

    • URL shorteners

    • News feeds

    • Messaging apps

    • Rate limiters




In your FAANG interview prep, build the habit of:

  • Asking clarifying questions before jumping into a design

  • Thinking in components: frontend, backend, database, cache, queue

  • Talking through trade-offs and failure points

  • Sketching diagrams and walking through user flow


You don’t have to be perfect—you just need to show structured thinking.



Step 6: Follow a Structured 8–10 Week Plan


Here’s a simple FAANG interview prep roadmap:

Weeks 1–3:

  • Core DSA (arrays, strings, hash maps)

  • Solve 2–3 problems/day

  • Write 3 behavioral stories


Weeks 4–6:

  • Graphs, recursion, DP

  • 2 mock interviews/week

  • Start watching system design videos


Weeks 7–9:

  • Mixed difficulty problems

  • Full mock interviews

  • System design walkthroughs

  • Finalize behavioral answers


Week 10:

  • Light revision

  • Simulate real interviews

  • Rest and recharge


You don’t need to be grinding 10 hours a day. Just 1–2 focused hours of intentional FAANG interview prep is enough—if you stay consistent.



Bonus: Top Tools and Platforms


Use a small, effective toolkit:

  • LeetCode: Best for DSA

  • Interviewing.io or Pramp: Realistic mocks

  • Excalidraw / Whimsical: System design diagrams

  • Notion / Google Sheets: Track progress

  • Glassdoor / Levels.fyi: Company-specific insights


Stick to what works—don’t spread yourself too thin across 20 platforms.



Final Thoughts:


The truth is, nobody walks into a FAANG interview feeling 100% ready. What matters is that you’ve put in consistent work, practiced smartly, and prepared across all areas: coding, behavioral, and system design.

FAANG interview prep isn’t about being the best. It’s about being prepared enough to think clearly, adapt quickly, and communicate effectively when it counts.

So start now. Stick to the basics. Be consistent. And when the opportunity comes, you won’t hope you’re ready—you’ll know you are.
