Use memory caches (like Redis) to store frequently requested predictions or static features.

Unlike algorithm coding questions, there is rarely a single "correct" answer. Interviewers evaluate your ability to make reasoned trade-offs—for example, choosing between a for recommendations versus a matrix factorization approach, or deciding between exact nearest neighbor search and approximate nearest neighbor (ANN) methods.
