Master the Android System Design Interview: Advanced Topics from Udemy

Take your mobile system design interview skills to the next level with this advanced course, building on the foundations laid in "Mastering the Android System Design Interview". If you’ve already mastered the basics, this course is your gateway to make you stand out in challenging and advanced system design topics — privacy, security, and modern Android app architecture — to ace your interviews at FAANG companies like Google, Apple, and beyond.

Led by Stefan, a seasoned Tech Lead from a Google Developer Agency, this course is built with over a decade of hands-on experience designing and developing Android, iOS, and multiplatform apps. Having successfully navigated system design interviews himself, Stefan understands the challenges and will share his expertise, practical tips, and interview-tested strategies to set you apart.

Mobile system design interviews are notoriously tough, with privacy and security being some of the least understood yet often critical areas. Additionally, modern Android app architecture requires a deep understanding of patterns, different architectural styles, and best practices to build scalable, maintainable apps. This course is specifically designed to address these gaps, giving you a competitive edge in your interviews. Despite the course being especially targeted at Android, many concepts are also applicable to iOS.

Over 20 hours of on-demand video content will cover what you need to know for your mobile system design interview:

Clean Code Principles: Apply DRY and SOLID principles to create codebases that are maintainable and easy to scale.
Architecture Patterns: Master
Clean vs. Layered Architecture: Learn how Clean Architecture focuses on the independence of business logic from frameworks, while Layered Architecture emphasizes logical separation into data, domain, and UI layers.
Android Architecture Components: Streamline your system design with ViewModel, LiveData, Flow, Room, DataStore, WorkManager, and other essential libraries.
Seamless Navigation: Simplify complex app flows using the Android navigation component.
Dependency Injection (DI): Leverage frameworks like Dagger, Hilt, Kodein, or Koin to make your code cleaner, more modular, and easier to test.
Mastering Modularization: Break down complex codebases into feature-based and/or layer-based modules for better scalability based on the principles of component cohesion and component coupling.
Android Privacy Fundamentals: Explore essential topics like permissions, location handling, data, transparency & control, app hibernation, and the Privacy Sandbox.
Cryptography: Understand symmetric cryptography, asymmetric cryptography, and hashing. Learn when to use each technique effectively.
Local Data Protection: Learn how to safeguard sensitive data stored on devices using encryption and secure storage solutions.
Network Data Protection: Explore strategies for securing data in transit, including SSL/TLS, certificate pinning, certificate transparency, and Android's network security configuration.
Authentication & Authorization: Implement secure user authentication based on standards like OAuth 2.0 and OpenID Connect, and session management.
Practical tips & tricks: Get additional tips & tricks, and a toolbox of clarifying questions to ask to tackle system design questions related to app architecture, privacy, and security.
Hands-On Learning: Practice solving architectural, and privacy & security challenges through 2 extensive mock interviews from requirements definition to high-level and detailed designs.
