System Architecture and Distributed Systems Questions

Assess understanding of system architecture and distributed system principles that drive technical program decisions. Topics include component decomposition data flow fault domains replication and partitioning strategies consistency and availability tradeoffs latency and throughput tradeoffs caching sharding load balancing scaling strategies capacity planning observability and failure modes. Interviewers evaluate how candidates articulate major design decisions justify tradeoffs reason about performance and cost and connect architecture choices to program scope timelines and risk.
