• Design a Notification System for Bursty Writes of 1M per SecondMedium

  System design question for a notification system that must absorb bursty traffic of about one million writes per second. It covers requirements and capacity estimates, a queue-buffered write path, why a log-structured store such as Cassandra writes quickly, channel delivery and deduplication.

• Design a Strongly Consistent, Fault-Tolerant Database for Fleet Validation DataMedium

  System design question about the database between an OS validation service that writes results and a fleet management service that reads them, with strong consistency required. It probes primary and replica failures, synchronous versus asynchronous replication, failover, two-phase commit and consensus.

• Design a predicate structure and filter records with comparison, AND and ORMedium

  Design a data structure for predicates that combine greater-than and less-than comparisons with AND and OR, then implement filter(data, predicate) to return the matching items. Tests recursive structure design, extensibility to new operators, evaluation with early exit, and handling of missing fields and type mismatches.

• Justify Building an In-House System Instead of Adopting an Existing SolutionMedium

  Hiring manager question asking why a team built a system in-house when existing industry solutions were available. It tests build-versus-buy reasoning about scale, cost and fit, honest accounting of ownership costs, and credible evidence of the candidate's own technical contribution.
