Subscription bundles combining grokking system design with interview prep
A FAANG interview loop typically includes 4–6 rounds: 2 coding rounds, 1 system design round, 1 behavioral round, and sometimes an OOD (object-oriented design) round or domain-specific round. Preparing for only one of these rounds and ignoring the rest is the equivalent of training for a triathlon by only swimming—you might excel in one event but still lose the race. In 2026, the most cost-effective and comprehensive preparation strategy is to buy a bundle that covers every round type rather than purchasing individual resources for each. Design Gurus' All Courses Bundle—which includes Grokking the System Design Interview alongside coding patterns, OOD, behavioral prep, and specialized tracks—provides lifetime access to the complete interview stack at up to 60% less than buying courses individually. This article compares every bundle option available and helps you choose the combination that matches your interview timeline and budget.
Key Takeaways
- FAANG interview loops test 4–6 different skill areas. Preparing for system design alone leaves you exposed on coding, OOD, and behavioral rounds—any of which can result in a "no hire" decision regardless of your system design performance.
- Design Gurus' All Courses Bundle provides the most comprehensive single-purchase option: system design (Fundamentals, Core, Advanced, Volume II), coding patterns (543 lessons across 24 patterns), OOD, behavioral, dynamic programming, microservices, and specialized tracks—all with lifetime access.
- Educative's Unlimited subscription ($39/month or discounted annually) provides access to 1,500+ courses across all interview types. Cost-effective for 2–3 month preparation sprints where you complete multiple courses and then cancel.
- ByteByteGo's platform covers system design and OOP visually with 7 books of content, but does not cover coding patterns or behavioral prep. It works best as a visual supplement alongside a primary bundle.
- The bundle decision comes down to: lifetime access vs subscription, and breadth of coverage. Design Gurus bundles provide focused interview prep with permanent ownership. Educative provides broader access including non-interview courses with time-limited subscription.
What a Complete FAANG Interview Prep Requires
Before comparing bundles, understand what the interview loop tests.
| Round | What It Tests | Typical Weight | Prep Resource Needed |
|---|---|---|---|
| Coding (2 rounds) | Data structures, algorithms, coding patterns | 30–40% | Coding patterns course + practice |
| System Design (1–2 rounds) | Architecture, scalability, trade-offs | 25–35% | System design course + mocks |
| Behavioral (1 round) | Communication, leadership, conflict resolution | 15–20% | Behavioral framework + stories |
| OOD / Low-Level Design (0–1 round) | Class design, SOLID principles, design patterns | 10–15% | OOD course |
| Domain-Specific (0–1 round) | Frontend, ML, mobile, or platform-specific | 5–10% | Specialized track |
The critical insight: A candidate who scores "strong hire" on system design and "no hire" on coding still receives a rejection. Bundles exist because the interview loop is holistic—you need to pass every round, not just the one you enjoy preparing for.
Design Gurus: The All Courses Bundle
What is included:
System Design Track:
- Grokking the System Design Interview — The flagship: 66 lessons, 18 case studies, Master Template
- Grokking System Design Fundamentals — Beginner entry point for building blocks
- Grokking the Advanced System Design Interview — L6+ depth: Dynamo, GFS, Kafka internals
- Grokking the System Design Interview, Volume II — Fresh problems: YouTube likes counter, Reddit, Google Calendar
Coding Track:
- Grokking the Coding Interview: Patterns for Coding Questions — 543 lessons covering 24 coding patterns in Java, Python, JavaScript, C++, C#, and Go. The most comprehensive coding interview course available.
- Grokking Dynamic Programming Patterns — DP-specific patterns for the questions candidates fear most
- The Coding Interview Roadmap — Mastering algorithms, data structures, and problem-solving
Design and Behavioral Track:
- Grokking the Object-Oriented Design Interview — SOLID principles, UML, and LLD problems (parking lot, elevator, library system)
- Grokking the Behavioral Interview — Frameworks for structuring STAR stories and answering leadership questions
- Grokking Microservices Design Patterns — Service decomposition, messaging, and event-driven patterns
Specialized Tracks:
- ML System Design, Frontend System Design, Mobile System Design, and additional specialized courses as they are released
Pricing: Up to 60% off versus buying individually. Use code GURU for additional discount. Lifetime access to all current and future courses.
Why the bundle stands out: Every course is built by ex-FAANG hiring managers using the same pattern-based methodology. The coding patterns course (543 lessons) is the most comprehensive alternative to random LeetCode grinding. The system design ecosystem (4 courses from Fundamentals through Advanced) covers every level from beginner to principal. Lifetime access means you return for future interview cycles without additional cost.
Sub-Bundles for Focused Preparation
System Design Bundle: Fundamentals + Core + Advanced + Volume II. For engineers who only need system design and already have coding and behavioral prep covered.
Coding Interview Roadmap Bundle: Coding patterns + Dynamic Programming + Algorithms roadmap. For engineers who need coding prep specifically.
These sub-bundles provide focused preparation at a lower price than the All Courses Bundle, but miss the cross-round coverage that holistic interview prep requires.
Why Bundles Outperform Individual Course Purchases
Beyond the price savings (up to 60%), bundles provide a structural advantage: the courses are designed to work together. The coding patterns course teaches decomposition skills that transfer to system design deep dives. The OOD course teaches interface design that strengthens API design discussions in system design rounds. The behavioral course teaches structured communication (STAR framework) that improves how you narrate your system design on the whiteboard.
Engineers who prepare with a bundle report that the skills compound across rounds. A candidate who learned the "two pointers" coding pattern and the "read-heavy vs write-heavy" system design trade-off in the same week starts seeing connections: the pointer technique for partitioning data maps to the sharding strategy for distributing load. These cross-domain connections build the integrated engineering judgment that interviewers at the staff level evaluate.
Certificate of Completion
Upon completing each course in the Design Gurus ecosystem, you receive a certificate of completion. While certificates are not a substitute for interview performance, they provide documentation of completed professional development—useful for employer reimbursement claims and LinkedIn profile credentials that signal ongoing investment in architectural skills.
Educative: Unlimited Subscription
What is included: Access to 1,500+ courses across all technology topics—system design, coding, cloud, ML, behavioral, and general software development.
System design content: "Grokking Modern System Design Interview for Engineers & Managers" (Educative's independently maintained version) plus courses on microservices, cloud architecture, and distributed systems.
Coding content: Multiple coding interview courses including data structures, algorithms, and language-specific prep.
Pricing: Standard (14.99/month), Premium (39/month), annual plans with 20–30% discount. The Premium plan provides unlimited access to all 1,500+ courses.
When Educative's subscription makes sense: For 2–3 month preparation sprints. Subscribe, complete system design in month 1, coding patterns in month 2, behavioral and OOD in month 3, then cancel. The per-month cost is low, and the breadth of access is unmatched. However, canceling loses all access—returning for a future interview cycle requires resubscribing.
Limitation: Educative's system design course is not the original Grokking created by Arslan Ahmad's team. The methodology and content differ from the DesignGurus.io version. The subscription model means you pay continuously for access you may only need periodically.
ByteByteGo: Visual Supplement
What is included: 7 books of visual content covering system design, OOP design, ML system design, and GenAI system design.
Pricing: 79–228/year. Lifetime plans available during periodic 50% sales.
What it covers well: System design concepts through the industry's best visual diagrams. OOP design visually. ML system design for engineers entering AI-focused roles.
What it does not cover: Coding patterns and algorithms. Behavioral interview preparation. Mock interview access. Practice problems with feedback.
Role in a bundle strategy: ByteByteGo works as a visual supplement alongside a primary interview prep bundle (Design Gurus or Educative), not as a standalone comprehensive solution.

TL;DR
FAANG interview loops test 4–6 skill areas (coding, system design, OOD, behavioral, domain-specific), and preparing for only one leaves you exposed on the others. Design Gurus' All Courses Bundle provides the most comprehensive single-purchase option: 4 system design courses (Fundamentals through Advanced), 543 coding pattern lessons across 24 patterns, OOD, behavioral, dynamic programming, and specialized tracks—all with lifetime access at up to 60% off (code GURU for additional savings). Educative's Unlimited subscription ($39/month) provides 1,500+ courses for time-limited preparation sprints—complete in 2–3 months, then cancel. ByteByteGo supplements any primary bundle with visual diagrams covering system design and OOP. The 8-week bundle study plan covers every FAANG round type at 1.5–2 hours daily: system design (weeks 1–2, 5), coding patterns (weeks 3–4, 6), behavioral (week 7), and mock interviews across all types (week 8). The bundle eliminates the most expensive preparation mistake: passing system design but failing coding, or passing coding but failing behavioral.
