During the interview, I outlined a distributed cache that addressed high availability and partition tolerance. I proposed using a distributed hash table for data storage and discussed replication strategies to enhance reliability.

The interviewer appreciated the emphasis on consistency models, but I stumbled a bit when digging into specific implementations. When asked about cache eviction policies, I hesitated, only briefly mentioning LRU without deeper insights.

This seemed to create a gap in my explanation, which the interviewer pointed out.
