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.
