description Overview

System Design Interviewing

This is less a coding skill and more a high-level engineering discipline. It involves designing large, complex systems (e.g., Twitter feed, URL shortener) from scratch, discussing trade-offs between consistency (CAP theorem), availability, latency, and cost. Interviewing for this skill proves you can think like an architect, anticipating failure modes, bottlenecks, and scaling requirements before...

LangGraph

LangGraph is an extension of the LangChain ecosystem designed specifically for building stateful, multi-actor applications. Unlike linear chains, it allows for cycles, making it ideal for complex agents that need to loop back and correct their own mistakes. It provides fine-grained control over the execution flow, persistence for long-running tasks, and native support for human-in-the-loop interac...
