AI system design interviews reward structure. Most candidates jump to a model; strong candidates first clarify the problem, then reason through data, retrieval, evaluation, and operations as a connected system.

A framework you can reuse

  • Clarify the task, users, and quality bar
  • Decide what knowledge the model needs and how it gets it
  • Choose retrieval, tools, or fine-tuning with explicit tradeoffs
  • Define evaluation and guardrails
  • Cover latency, cost, scale, and failure modes
note

You are not being tested on knowing the newest model. You are being tested on reasoning about tradeoffs under constraints.
