Practice Problem Reference

The problems/ directory is rehearsal material, not the final interview deliverable.

Included Prompts

• 01-service-registry: service health, dependency graph queries, and transitive impact analysis
• 02-api-audit-log: latency percentiles, retry detection, and time-window anomaly analysis
• 03-deploy-reconciliation: desired-vs-actual drift detection across environments
• 04-record-linkage: schema mapping, exact and fuzzy matching, and ambiguity reporting

Generator

problems/generate.py regenerates the JSON fixtures used by the practice prompts.

• deterministic seed: random.seed(42)
• writes under each problem directory
• CI runs it before tests
