Deep technical project narrative and lessons learned Questions
Prepare detailed discussion of a significant project: the problem, your approach, technical decisions and trade-offs, challenges and how you overcame them, outcome, and what you learned. Practice explaining this clearly in 10-15 minutes, leaving time for questions.

You evaluated two architectures (for example monolith vs microservices). Prepare a concise comparative analysis across operational cost, deployment complexity, developer productivity, testing burden, and long-term extensibility. State which approach you chose for the project and provide a detailed rationale including migration risks.

Identify the main internal and external stakeholders for the project (e.g., PM, designers, legal, ops, customers). For each stakeholder group, explain their primary concern, how and how often you engaged them, and one concrete example of a compromise or alignment you negotiated during the project.

How did you evaluate and prioritize technical debt against shipping new features during the project? Describe the criteria you used (risk, customer impact, cost to fix), a concrete example you prioritized, and any measurable impact from addressing or deferring debt.

Describe the top three technical decisions you made during the project. For each decision, state: (a) the alternative options you considered, (b) the objective criteria you used to choose (e.g., latency, cost, maintainability, schedule), and (c) a short justification and outcome. Limit each decision explanation to one or two minutes.

Draw or describe the high-level architecture you built: list components, data flows, external dependencies, and the primary communication protocols (e.g., HTTP, gRPC, message queues). For each major component, justify why it exists and what constraints it addresses (latency, throughput, cost, maintainability). You may sketch a concise ascii diagram.
