Question: Design a resilient file system that can recover file content after a system crash. There was no coding involved, just design considerations.
The problem statement was very broad, requiring the design of a resilient file system. My design needed to ensure file content could be recovered after a system crash. I approached the problem by referencing commonly asked questions for file system design. The interviewer followed up with questions about bottlenecks and how to modify the design for production.
