Questions that explore dialogue flow design, voice UX principles, and building AI assistants that feel natural and reliable.
10 questions3 categoriesWith answer hints
Technical
4 questions1What is the difference between intent recognition, entity extraction, and dialogue management in a conversational AI system?
Hint: Intent: what the user wants (book_flight). Entity: the parameters of that intent (destination=Paris, date=Friday). Dialogue management: state machine or LLM that decides the next turn based on context and fulfilled/unfulfilled slots.
2What are the key differences between designing for voice interfaces versus text-based chat?
Hint: Voice: no visual affordances, no scroll, no retry button, output must be heard in linear sequence. Implications: shorter responses, spoken-friendly language (no tables or lists), confirmation before irreversible actions, clear barge-in handling.
3How do you handle ambiguous user input in a conversational AI design?
Hint: Strategies: clarification questions (ask for the missing slot), top-N disambiguation (show candidate interpretations), graceful fallback with repair suggestions, and confidence thresholds that trigger human escalation.
4What is a conversation repair strategy, and why is it critical to conversational AI quality?
Hint: Repair: how the system recovers from misunderstandings. Good repair acknowledges the error, corrects course without blaming the user, and continues toward the goal. Poor repair (generic "I didn't understand") damages trust permanently.
Behavioral
3 questions5Tell me about a conversational flow you designed that had a high fallback rate. How did you diagnose and improve it?
Hint: Cover analysis of fallback transcripts (what were users actually saying?), intent model retraining with new utterances, flow restructuring to reduce out-of-scope prompts, and measuring improvement in task completion rate.
6Describe a time you had to design for a persona that was very different from your own communication style. What did you learn?
Hint: Shows empathy and research process: user interviews, tone analysis of existing communications, A/B testing response styles. Cover how you validated the persona's voice with real users.
7Tell me about a conversational AI experience you used as a user that you found genuinely delightful. Why did it work?
Hint: Shows taste and analytical ability. Deconstruct the experience: what made it feel natural (proactive help, appropriate brevity, graceful error handling), and what principles you've applied in your own work.
System Design
3 questions8Design a conversational AI assistant for a bank's customer service channel handling 50,000 interactions per day.
Hint: Cover intent taxonomy (account inquiry, dispute, transfer, complaints), escalation policy (sentiment detection → human handoff), knowledge base integration, PII handling in transcripts, CSAT measurement, and continuous improvement workflow.
9How would you design a voice assistant for a smart home device that must work reliably in a noisy kitchen environment?
Hint: Cover wake word design (false positive rate in ambient noise), short prompt design, confirmation patterns for commands with consequences (turning off oven), graceful degradation when confidence is low, and multimodal fallback (screen if available).
10Design a conversation design system (style guide + component library) for a team of 10 dialogue designers.
Hint: Cover persona documentation, tone and voice guidelines, response template library (confirmations, errors, disambiguations), utterance variation standards, testing scripts, and governance for contributing new flows to the shared library.
