Technical practice
How would you turn multimodal signals into a useful picture of a user's current context?
What to coverSuggested preparation: Explain how you would combine signals while accounting for missing, conflicting, or uncertain inputs. Discuss how you would test whether the resulting context helps the assistant respond usefully.
How would you design memory that supports personalization over time?
What to coverSuggested preparation: Distinguish short-lived context from information worth retaining, and explain how memories could be updated or corrected. Address the trade-off between useful continuity and unnecessary retention.
How would you retrieve and rank context for an assistant response?
What to coverSuggested preparation: Walk through a retrieval approach using embeddings, ranking, or RAG where appropriate. Explain how you would balance relevance, freshness, and the amount of context supplied to the model.
How would you decide when an assistant has enough context to reason or take action?
What to coverSuggested preparation: Describe how you would handle incomplete or contradictory context before producing an answer or action. Discuss the trade-off between timely assistance and acting on weak evidence.
How would you compare open-source models for this assistant?
What to coverSuggested preparation: Explain how you would run and evaluate candidate LLMs, VLMs, or multimodal models against the intended tasks. Discuss when adapting a model might be worthwhile rather than changing its context or retrieval pipeline.
How would you structure the Python backend and AI pipeline from inputs to assistant output?
What to coverSuggested preparation: Sketch the responsibilities of model workflows, APIs, storage, and pipeline components without assuming a particular stack. Explain how you would make failures observable and keep component boundaries clear.
How would you protect user privacy and data boundaries in context and memory systems?
What to coverSuggested preparation: Explain where sensitive information could enter, persist, or cross a boundary in a personalized assistant. Discuss how you would limit access and retention while preserving useful functionality.
How would you evaluate and monitor the assistant after launch?
What to coverSuggested preparation: Separate checks of context quality, retrieval, personalization, and end-to-end usefulness. Explain what monitoring would help identify degraded behavior or privacy-related failures without unnecessarily exposing user data.
When would you use an MCP server or agent framework in this system?
What to coverSuggested preparation: Explain what each could contribute to giving a model external context or capabilities. Weigh that benefit against added complexity, reliability concerns, and data-boundary risks.
How would you troubleshoot an assistant that gives irrelevant responses despite having relevant stored context?
What to coverSuggested preparation: Trace the path from stored information through retrieval, ranking, context assembly, and model output. Explain how you would isolate the failure before changing the model or pipeline.
Behavioural practice
Tell me about a time you turned an ambiguous need into a working AI capability.
What to coverSuggested preparation: Use a real situation/action/result example, explaining how you clarified the need and chose an initial implementation. State what the result showed and what you changed as you learned.
Describe a time you owned an applied AI system from implementation through use.
What to coverSuggested preparation: Use a real situation/action/result example that distinguishes your decisions from the team's work. Explain how you handled evaluation, operational issues, or follow-through after shipping.
Tell me about a time you worked with product, design, and engineering on an uncertain problem.
What to coverSuggested preparation: Use a real situation/action/result example showing how you communicated technical trade-offs and resolved differing priorities. Describe the resulting decision and its effect on the work.
Describe a time you balanced fast execution with a data or user-protection concern.
What to coverSuggested preparation: If you have a relevant real example, explain the situation, your action, and the result. Focus on how you made the trade-off visible and preserved an appropriate boundary rather than claiming speed and protection never conflicted.
Tell me about a time feedback changed your technical approach.
What to coverSuggested preparation: Use a real situation/action/result example that shows how you listened, tested an assumption, and revised your approach. Explain what improved and what you learned.
