How to Prepare for a FAANG Interview
I will be straight with you: preparing for a FAANG interview (or any top-tier tech company) takes real, sustained effort. There is no two-week crash course that reliably works. But with the right strategy and enough runway, the process is very learnable.
Here is what actually works, based on what I have seen from candidates who got offers and what I have seen from candidates who didn't.
What the Interview Process Looks Like
Most FAANG companies follow a similar playbook:
1. A recruiter screen. 30 minutes. They are checking for fit and logistics, not testing you technically. 2. A technical phone screen. 45 to 60 minutes. Usually one coding problem, sometimes system design for more senior roles. 3. An on-site loop. Three to five interviews over one day (or spread across multiple virtual sessions). This covers coding, system design, behavioral, and sometimes domain-specific topics. 4. Hiring committee review and the decision. 5. Team matching (at some companies, like Google). You get matched to a specific team after the committee approves you. 6. Offer and negotiation.
A Realistic Preparation Timeline
3 to 4 Months Out: Build the Foundation
Coding. Go back to the fundamentals if you need to. Arrays, trees, graphs, hash maps, heaps. Sorting, searching, dynamic programming, BFS, DFS. Start solving problems. Aim for 100 to 150 total across easy, medium, and hard. Don't just grind. After each problem, understand *why* the solution works. Look for patterns across similar problems.
System Design. Start reading about distributed systems. Load balancing, caching, database sharding, message queues, CAP theorem, consistency models. If you have never worked on systems at scale, this is the area that takes the longest to develop genuine fluency.
Behavioral. Start a document where you write down your career stories. Projects you led, conflicts you navigated, failures you learned from, times you had outsized impact. You will refine these later, but start capturing the raw material now.
1 to 2 Months Out: Focused Practice
Coding. Shift to medium and hard problems. Practice under time pressure: 35 to 40 minutes per problem, just like the real thing. Review common patterns (sliding window, two pointers, topological sort, union-find) and know when to apply them.
System Design. Practice designing 8 to 10 common systems end-to-end. Talk through them out loud. Focus on articulating trade-offs and explaining why you made each decision.
Behavioral. Distill your stories into 8 to 10 polished narratives. Make sure they cover leadership, conflict, failure, collaboration, and measurable impact. Practice telling each one in under three minutes.
2 Weeks Out: Mock Interviews and Polish
Do at least three to five mock interviews. Ideally with someone who has interview experience at your target companies. Self-study can only take you so far. You need to experience the pressure of performing in front of someone, getting follow-up questions you didn't expect, and managing your time when the clock is real.
Double down on whatever the mocks reveal as weak spots. And handle logistics: confirm your schedule, test your video setup, plan your day so you are not stressed about non-interview stuff.
The Biggest Preparation Mistake
Here it is: treating FAANG interview prep as a purely technical exercise. I see this all the time. Candidates who can solve hard LeetCode problems in their sleep but can't clearly explain their thought process, or who ace coding rounds but stumble through system design, or who have great technical skills but can't tell a compelling behavioral story.
The companies are evaluating the whole package. My rule of thumb: spend at least a third of your prep time on non-coding dimensions. System design and behavioral interviews carry just as much weight as coding in committee decisions, sometimes more for senior roles.
What Actually Gets You the Offer
Consistency across every round. The committee isn't looking for one brilliant performance. They look for solid, reliable signals in every dimension. Peaks don't compensate for valleys.
