Technical Literacy for Project Management Questions

Knowledge and communication skills that enable a project manager to credibly engage with engineering and technical teams. Candidates should demonstrate familiarity with system architecture concepts, application programming interfaces, databases, cloud platforms and deployment models, testing and monitoring strategies, security and compliance considerations, and scalability and performance trade offs. This includes understanding technical choices such as monolith versus microservices or SQL versus NoSQL, estimating technical effort, reading and interpreting technical documentation and diagrams, facilitating technical discussions, translating product requirements into technical constraints, and working with engineers to surface and mitigate technical risks.

Architect a data pipeline that supports near-real-time dashboards and batch ML model training. Cover ingestion (stream vs batch), handling late-arriving events and schema evolution, watermarking strategy, storage choices (OLAP vs object store), backfills, and provide a rough approach to estimate storage and compute costs.

Compare monolith and microservices from a product and operational perspective. Explain how each affects release cadence, testing complexity, reliability, team organization, and roadmap pacing. Provide two signals that indicate a team should avoid moving to microservices right now.

Design a comprehensive test strategy for a critical payment flow: include unit, integration, contract, end-to-end, security, and performance tests. Specify pass/fail criteria, test data management (sandbox vs production), and how you'd monitor the flow post-deployment.

Design a scalable chat architecture to support 5 million daily active users with peak 200k concurrent connections and message throughput 10k msgs/sec. Outline components (ingestion, presence, routing, storage, search), partitioning/sharding strategy, consistency model, caching, and how you'd handle multi-region latency and compliance constraints. Discuss monolith vs microservices trade-offs.

Design an incident response and postmortem process for a critical outage: checkout failures for 2 hours on Black Friday. Define communication cadence, on-call roles and rotation, mitigation steps, data collection for RCA, a blameless postmortem template, and how to ensure corrective actions are tracked and implemented.
