Gap Analysis: Current vs. Production-Ready

Last Updated: Feb 1, 2026
Overall Completion: ~55%

Critical Gaps (Blocking Production Release)

1. V1→V2 Migration Incomplete

• Status: ❌ BLOCKING
• Current: v2 folders (04-System-Design-Library/, 05-ML-MLOps/, 06-Data/, 07-Infra-DevOps/) have only index stubs
• Legacy exists: Full content in v1 folders (04-SYSTEM-DESIGN-LIBRARY/, 05-ML-MLOPS/, 06-DATA/, 07-INFRA-DEVOPS/)
• Impact: Users must navigate two parallel trees; confusing
• Fix: Copy 18 files from v1 into v2 structure
• Effort: 1–2 hours

2. Real Interview Experiences Missing

• Status: ❌ BLOCKING
• Current: 08-Company-Specific-Notes/ has only 5 high-level files (40–80 lines each)
• Required: Google.md, Amazon.md, Meta.md, Apple.md, Netflix.md with:
  • Actual interview rounds (coding + system design + behavioral)
  • Common questions + how to approach them
  • Real feedback snippets ("you talked too fast," "good edge cases")
  • Company-specific rubrics
• Impact: Candidates don't know what to actually expect
• Fix: Create 5 detailed company guides (500–800 lines each)
• Effort: 4–6 hours

3. Study Schedules Not Detailed

• Status: ⚠️ CRITICAL
• Current: 06-Study-Plans/ referenced in README but folder exists only in legacy 08-CAREER/
• Required:
  • junior-3-month-plan.md (weekly breakdown, daily tasks)
  • mid-6-month-plan.md (weekly breakdown, daily tasks)
  • senior-4-month-plan.md (weekly breakdown, daily tasks)
• Format: Week-by-week calendar with specific topics + reps
• Impact: Candidates don't know what to do on Monday
• Fix: Create 3 detailed schedules (300–400 lines each)
• Effort: 3–4 hours

4. Mock Interview Feedback Templates Missing

• Status: ❌ BLOCKING
• Current: 05-Mock-Interviews/ has only stub
• Required:
  • Self-evaluation rubric (coding + system design + behavioral)
  • Peer review template (feedback format)
  • Post-interview debrief checklist
  • Video/async interview guide
• Impact: Candidates can't measure progress
• Fix: Create 4 templates (200–300 lines each)
• Effort: 2–3 hours

5. Governance Files Missing

• Status: ⚠️ IMPORTANT
• Current: No CONTRIBUTING.md, LICENSE, CHANGELOG
• Required:
  • CONTRIBUTING.md (how to add interview experiences, company-specific tips)
  • LICENSE.md (MIT or CC-BY-4.0)
  • CHANGELOG.md (version history)
  • .gitignore + git init setup
• Impact: Not professionally shareable on GitHub
• Fix: Create 4 files (~100–200 lines each)
• Effort: 1–2 hours

High-Priority Gaps (Significant Content Missing)

6. Real Engineer Quotes + Stories Limited

• Status: ⚠️ HIGH
• Current: Mostly references to official docs (TIH, Amazon, Google)
• Missing: Personal stories, failure cases, unexpected insights
• Examples needed:
  • "I failed my first Amazon loop because I didn't ask clarifying questions" → how to avoid
  • "Meta cares more about tradeoffs than perfect code" → interview insight
  • "Google's bar raiser round is different; they probe deeper on one topic"
• Fix: Integrate into company-specific docs (add 10–15 real stories)
• Effort: 3–4 hours (needs research or crowdsourcing)

7. DSA Content Not in V2 Structure

• Status: ⚠️ HIGH
• Current: DSA lives in legacy 01-FOUNDATIONS/01-DSA-and-Coding.md; referenced in v2 but not expanded
• Missing: Structured DSA roadmap with:
  • Topic-by-topic breakdown (arrays, strings, trees, graphs, DP)
  • Interview patterns (two pointers, sliding window, BFS/DFS, etc.)
  • Common mistakes (off-by-one, edge cases, complexity errors)
  • LeetCode problem mapping (which problems test what)
• Fix: Create v2 DSA folder with 7–8 detailed guides
• Effort: 4–5 hours

8. Resume ATS Optimization Not Detailed

• Status: ⚠️ HIGH
• Current: 04-Resume-LinkedIn-GitHub/ reference in README, but exists only in legacy
• Missing:
  • ATS keyword list for each role (backend, MLE, SRE, etc.)
  • Resume templates with real examples
  • What kills resumes (common mistakes)
  • Action verb list + metrics
• Fix: Create v2 resume section with 3–4 detailed guides
• Effort: 2–3 hours

9. System Design Example Solutions Incomplete

• Status: ⚠️ MEDIUM
• Current: 02-System-Design/example-designs/ mentioned in spec but exists only as legacy
• Missing: Deep dive for URL shortener, news feed, chat, rate limiter, file storage
• Current in legacy: Generic templates but not real solutions
• Fix: Write 5 example solutions (300–400 lines each)
• Effort: 4–6 hours

10. Company Leveling + Salary Context

• Status: ⚠️ MEDIUM
• Current: 08-Company-Specific-Notes/05-Geography-Leveling.md exists but is bare
• Missing:
  • IC level definitions (IC1→IC7)
  • What each level expects in interviews
  • Approximate salary ranges (anonymized data)
  • How to negotiate level
• Fix: Expand 05-Geography-Leveling.md (500+ lines)
• Effort: 2–3 hours

Lower-Priority Gaps (Nice-to-Have)

11. Negotiation Specifics by Company

• Status: ℹ️ NICE-TO-HAVE
• Current: 07-Offer-Negotiation/ referenced in legacy but sparse
