🚀 Struggling with Big Tech interview prep? Book a 1-on-1 mentorship session to master mobile system design, coding, and behavioral rounds, with realistic mock interviews and actionable feedback from an ex-Meta engineer. 👉 https://andrey-tech.com In this video, I present my toolkit with the 5 most important concepts for mobile system design interviews. We dive into API Communication Protocols (including REST, WebSockets, GraphQL, and gRPC); explore Real-Time Updates through HTTP Polling, HTTP Long Polling, Server-Sent Events, WebSockets, and Push Notifications; examine Storage solutions such as Key-Value Storage, Databases, File Storage, and Secure Storage; break down Pagination strategies like Limit-Offset, Page-Based, Keyset, and Cursor-based; and finally, cover Dependency Injection for building modular, testable mobile applications.
