Sample interview questions
I would explain how I gathered requirements from technical and business users, identified system boundaries and risks, designed the API and data model, delivered in incremental releases, and established observability, documentation, and an ownership model after launch.
I would define narrow, well-documented tools with strongly typed input and output schemas, enforce authentication and authorization at the service boundary, validate inputs, apply least-privilege data access, and provide predictable error handling. I would also add logging, audit trails, versioning, rate limits, and tests for both successful and failure paths.
I first map the business rules, inputs, outputs, exceptions, and current pain points with the users. Then I separate domain logic from the interface, implement validated APIs or workflow steps, migrate historical edge cases into tests, and release the solution gradually with monitoring and clear user documentation.
I constrain the model’s role with structured prompts and schemas, use tool calls with validated parameters, keep critical business logic outside the model, and add guardrails for retries, fallbacks, and human review where needed. I also evaluate representative cases continuously and log inputs, tool calls, outputs, and failure modes for debugging.
I assess requests by business impact, risk reduction, effort, dependencies, and alignment with platform strategy. I make tradeoffs transparent, propose phased delivery when useful, and prioritize reusable solutions that reduce repeated manual work rather than repeatedly solving isolated requests.
