Top Interview Questions
Sorted by reported frequency
Key Concepts to Master
Consistent HashingDistributed Systems
A distributed hashing scheme that minimizes key remapping when nodes are added or removed.
Database ShardingData Systems
Horizontal partitioning of a database across multiple machines to distribute load beyond a single server's capacity.
Message QueueSystem Design
Asynchronous communication buffer between services. Decouples producers from consumers and provides durability during traffic spikes.
Distributed CachingData Systems
A shared cache layer across multiple nodes used to absorb read traffic from the primary database and reduce latency on hot data paths. The difference between a 2ms and a 200ms read at scale.
