Coding Interview Prep: Designing a Ride-Sharing System in Elixir

Preparing for modern backend engineering interviews requires more than just memorizing algorithms; you need to know how to design scalable, real-time systems. This text-only course guides you through the core architectural patterns of a high-concurrency ride-sharing system using Elixir. You will transition from understanding basic functional programming concepts to mapping out complex, distributed services that interviewers look for in top-tier candidates. What you'll learn: - Understand the fundamental concepts of Elixir concurrency, OTP behaviors, and functional data structures. - Design a distributed, real-time location tracking system using Elixir processes and state management. - Apply fault-tolerant supervision trees to ensure high availability during simulated system stress. - Analyze ride-matching algorithms and database persistence strategies tailored for high-write loads. - Practice explaining your architectural decisions clearly using standard technical interview frameworks. - Leverage modern Elixir telemetry and testing practices to validate system performance and reliability. You will start with foundational Elixir syntax and concurrency primitives before progressively building up to complex subsystems like geospatial indexing and dispatch mechanics. Each module reinforces your learning with written step-by-step breakdowns and architectural analysis. This course is designed for aspiring backend developers and software engineers preparing for system design interviews. No advanced Elixir experience is required, as we start with foundational concepts before moving to complex system design. Start reading today to build the system design skills needed to stand out in your next technical interview.
