System Design Interview · 60 min · Principal Engineer or Architect
This round evaluates your ability to design complex, large-scale systems. You'll be presented with an open-ended problem (e.g., design Twitter's feed, a URL shortener, a distributed cache) and expected to create a high-level design. This involves defining requirements, estimating scale, choosing appropriate technologies, designing APIs, databases, and considering aspects like caching, load balancing, and fault tolerance.
