#Architecture

What are load balancers, and what are the different types that exist (e.g., Application, Network)?

Discuss your experience with large-scale backend systems, particularly regarding state machines using Temporal, distributed logging, and handling retries and fault tolerance.

Discuss the design of a cache system. Cover concepts such as LRU (Least Recently Used) and LFU (Least Frequently Used) caching strategies and their implications.

Design a Logger System that supports both Synchronous and Asynchronous logging, implements multiple log levels, supports multiple output sinks (starting with STDOUT), and ensures thread safety and performance. Focus on clean code, extensible architecture, design patterns, and testability.

This round will focus on low-level design based on a real-world problem that aligns with Rippling’s product. You should define classes, enums, and their relationships while discussing scaling and trade-offs and tying them to your project experience.
