Behavioral Questions

Describe a time you shipped an AI feature from prototype to production.

Cover the transition from notebook to production code, including testing, monitoring, and scaling.

Tell me about a time you had to work with a model that was a black box to your team.

Show how you built trust through evaluation, testing, and incremental rollout.

How do you evaluate and select third-party AI APIs versus building in-house capabilities?

Discuss cost modeling, vendor lock-in, latency, data privacy, customization needs, and build/buy frameworks.

Technical Questions

How do you choose between fine-tuning a model and using retrieval-augmented generation for a given use case?

Compare cost, latency, data requirements, update frequency, and accuracy trade-offs.

How do you design an embedding pipeline for semantic search at scale?

Discuss embedding model selection, vector databases, indexing strategies, and query optimization.

How do you implement guardrails and output validation for LLM-powered features?

Discuss content filtering, structured output parsing, fallback logic, and human-in-the-loop escalation.

Situational Questions

Your AI feature's API costs are 5x over budget. How do you optimize without degrading quality?

Cover caching, batching, model distillation, prompt optimization, and tiered service levels.

A user reports that your AI feature gave a confidently wrong and potentially harmful answer. How do you respond?

Address immediate user communication, logging investigation, and systemic improvements to prevent recurrence.
