Technical Risk Assessment and Mitigation Questions
Technical risk assessment and mitigation covers systematically identifying, prioritizing, and addressing potential failure modes and implementation pitfalls across architecture, integration, data migration, scalability, performance, security, third party dependencies, and team skill gaps. Candidates should demonstrate methods for analyzing and categorizing risks, such as fault tree analysis and failure mode and effects analysis, and describe practical mitigations including staged rollouts, canary deployments, redundancy and failover, rollback and contingency plans, increased testing, capacity planning, security hardening, monitoring and observability, runbooks, and training or vendor support. Interviewers expect discussion of validation strategies for mitigations, including dry runs, experiments, load and performance testing, chaos engineering, staged deployments, and monitoring driven verification before full production release. Strong answers will show how to prioritize by likelihood and impact, trade off cost and schedule, define measurable success criteria, and iterate on mitigations based on operational feedback.

Describe a zero-downtime schema migration approach for a cross-service denormalization that requires migrating a large table and updating 50 microservices to a new API contract. Provide step-by-step mitigations, detection strategies, staged rollouts, backfills, dual-read/dual-write phases, and a clear rollback plan.

Design a resilient, low-latency global checkout architecture for an e-commerce platform operating in three regions with targets: RTO < 30 seconds and RPO < 5 minutes during a region outage. Address data replication, order consistency, payment processing, inventory accuracy, reconciliation, and migration strategies to reduce rollout risk.

Describe Fault Tree Analysis (FTA) and explain how you'd construct a fault tree to diagnose a production outage where a global microservice returns intermittent 503 errors. Explain how you identify leaf events, use AND/OR gates, and combine historical failure probabilities to estimate the top-event risk.

A distributed system using message queues observes message duplication under high throughput. Design mitigation strategies to provide at-least-once or exactly-once semantics, discuss trade-offs in complexity and cost (idempotency, deduplication store, transactional outbox, broker features), and propose validation tests to ensure correctness under production load.

Describe a security hardening checklist to reduce technical risk before a production launch of a multi-service platform. Include automated tools (SAST, DAST), secrets management, least-privilege IAM, runtime protections (WAF, RASP), dependency scanning, and verification steps for compliance-sensitive systems.
