Context Engineering in Interviews
Answering context limits and search scaling questions in live technical panels.
Why This Matters
System designers must show how they manage prompt structures to optimize costs and latency.
Deep-Dive Explanation
Interviewers want to see how you design production setups that remain robust under heavy user interactions. When discussing context windows, emphasize practical limits (lost-in-the-middle, cost constraints) rather than just stating the theoretical limits (e.g., 200k tokens). Explain how you combine local embedding lookups with dynamic prompt builders to structure inputs.
