An AI engineer interview question focuses on managing the context window of large language models, treating it as a limited resource. Effective strategies include setting a token budget for system prompts, conversation history, and retrieved evidence, and prioritizing stable elements for caching. Advanced techniques involve tiered memory management, compressing older conversations, and using retrieval with reranking to pass only the most relevant context, strategically placed at the beginning or end of prompts. The question also highlights common pitfalls like overstuffing the context window, accidental truncation, and inadequate memory summarization, emphasizing the need for careful budgeting and measurement of performance metrics like latency and cost.
