12-Week Study Plan

A structured plan that progressively builds skills from foundations to full interview readiness.

from datetime import datetime, timedelta

class FAANGStudyPlan:
    def __init__(self, start_date):
        self.start = datetime.strptime(start_date, "%Y-%m-%d")
        self.weeks = {}

    def add_week(self, week_num, focus, problems_per_day, topics):
        week_start = self.start + timedelta(weeks=week_num - 1)
        self.weeks[week_num] = {
            "focus": focus,
            "problems": problems_per_day * 7,
            "topics": topics,
            "start": week_start.strftime("%b %d")
        }

    def summary(self):
        for week, details in sorted(self.weeks.items()):
            print(f"Week {week:2d} ({details['start']}): {details['focus']}")
            print(f"     {details['problems']} problems | Topics: {', '.join(details['top'])}")

plan = FAANGStudyPlan("2026-07-01")
plan.add_week(1, "Arrays & Strings", 2, ["two pointers", "sliding window", "prefix sum"])
plan.add_week(2, "Linked Lists & Stacks", 2, ["reversal", "cycle detection", "monotonic stack"])
plan.add_week(3, "Trees & Graphs", 2, ["BFS", "DFS", "binary tree traversals"])

Company-Specific Focus

Each FAANG company emphasizes different aspects in interviews.

company_focus = {
    "Google": {
        "coding": "hardest, focuses on algorithmic thinking",
        "system_design": "medium-high, practical systems",
        "behavioral": "lightweight, 1 round",
        "extra": "googleyness and leadership"
    },
    "Meta": {
        "coding": "medium-hard, speed matters",
        "system_design": "high, distributed systems focus",
        "behavioral": "heavy, 2 rounds on execution",
        "extra": "product sense and speed"
    },
    "Amazon": {
        "coding": "medium, practical problems",
        "system_design": "medium, scalability focused",
        "behavioral": "heaviest, leadership principles",
        "extra": "bar raiser round"
    },
    "Apple": {
        "coding": "hard, depth over breadth",
        "system_design": "medium-high, domain-specific",
        "behavioral": "medium, cross-functional focus",
        "extra": "domain expertise matters"
    },
    "Netflix": {
        "coding": "medium, clean code valued",
        "system_design": "high, microservices focus",
        "behavioral": "heavy, culture and judgment",
        "extra": "freedom and responsibility"
    }
}

for company, details in company_focus.items():
    print(f"{company}:")
    for aspect, desc in details.items():
        print(f"  {aspect}: {desc}")
    print()
Google:
  coding: hardest, focuses on algorithmic thinking
  system_design: medium-high, practical systems
  behavioral: lightweight, 1 round
  extra: googleyness and leadership

Meta:
  coding: medium-hard, speed matters
  system_design: high, distributed systems focus
  behavioral: heavy, 2 rounds on execution
  extra: product sense and speed
...
import java.util.*;

public class CompanyFocus {
    public static void main(String[] args) {
        Map<String, String> prepRatios = new HashMap<>();
        prepRatios.put("Google", "80% coding, 15% system design, 5% behavioral");
        prepRatios.put("Meta", "50% coding, 30% system design, 20% behavioral");
        prepRatios.put("Amazon", "40% coding, 20% system design, 40% behavioral");
        prepRatios.forEach((c, r) -> System.out.println(c + ": " + r));
    }
}
Google: 80% coding, 15% system design, 5% behavioral
Meta: 50% coding, 30% system design, 20% behavioral
Amazon: 40% coding, 20% system design, 40% behavioral

Resume Optimization

Your resume passes through both ATS and human review. Follow these rules:

class ResumeCheck:
    def __init__(self):
        self.rules = [
            ("Quantify achievements", "increased x by y%", True),
            ("Single page", "length <= 1 page", True),
            ("Role-specific keywords", "target role appears 5+ times", True),
            ("Action verbs", "led, designed, built, optimized", True),
            ("Degree + GPA", "if > 3.5 include GPA", True),
            ("No buzzword stuffing", "avoid 90s tech", True),
            ("Reverse chronological", "newest first", True),
        ]

    def check(self, resume_text):
        issues = []
        for rule, hint, required in self.rules:
            issues.append({"rule": rule, "hint": hint, "pass": False})
        return issues

checker = ResumeCheck()
print([r["rule"] for r in checker.check("")])
['Quantify achievements', 'Single page', 'Role-specific keywords', 'Action verbs', 'Degree + GPA', 'No buzzword stuffing', 'Reverse chronological']
#include <iostream>
#include <string>
#include <vector>
using namespace std;

struct ResumeRule {
    string rule;
    string hint;
};

int main() {
    vector<ResumeRule> rules = {
        {"Quantify results", "Use numbers: increased, reduced, led"},
        {"Single page", "Keep to one page for <10 years experience"},
        {"Keywords", "Match job description keywords exactly"},
        {"Action verbs", "Start bullets with strong action verbs"}
    };
    for (auto& r : rules) {
        cout << r.rule << ": " << r.hint << endl;
    }
    return 0;
}
Quantify results: Use numbers: increased, reduced, led
Single page: Keep to one page for <10 years experience
Keywords: Match job description keywords exactly
Action verbs: Start bullets with strong action verbs

Common Mistakes

  1. Applying to all companies at once -- Apply to 1-2 target companies first, learn from the Process, then apply to others. Each rejection teaches something valuable.
  2. Ignoring behavioral preparation -- Amazon and Meta weight behavioral at 40%+. Technical perfection cannot save a poor behavioral round.
  3. No mock interviews -- Solving problems alone is different from solving them with someone watching. Do at least 5 mock interviews before real ones.
  4. Cramming LeetCode without patterns -- Solving 300 problems randomly is less effective than solving 100 problems by pattern with deep understanding.
  5. Not researching the specific team -- Generic preparation misses team-specific requirements. Research the team's tech stack and challenges before each interview.
  6. Poor time management during interviews -- Spending 30 minutes on one problem with no solution is worse than solving two problems partially. Set time limits and move on.
  7. Neglecting System Design for senior roles -- Senior+ roles weight System Design at 50%+. Start System Design prep 4 weeks before interviews.

Practice Questions

1. Create your personal 12-week study plan based on your current skill level.

Assess yourself on each topic (1-5 scale), allocate more time to weak areas, and schedule mock interviews from week 8 onward.

2. Research and list the interview format for your target company.

Each FAANG company has different rounds. For example, Google has 4 coding + 1 System Design + 1 behavioral. Amazon has 3 coding + 1 System Design + 2 behavioral (LP-focused).

3. Challenge: Complete a full mock interview day.

Schedule 4 back-to-back 45-minute coding rounds with a friend or using a mock interview platform. Record your performance and identify patterns in mistakes.

FAQ

How many LeetCode problems should I solve for FAANG?

Target 150-200 problems with quality over quantity. Cover all 15 core patterns. Focus on understanding and explaining solutions, not memorizing them.

How far in advance should I start preparing?

12 weeks is the recommended minimum. 16-20 weeks if you are starting from weak foundations. 8 weeks if you are actively interviewing and need a refresher.

Should I apply through referral or directly?

Referrals increase interview rate by 3-5x. Network with current employees, attend company events, and use LinkedIn to find referrals. Avoid applying through generic portals.
