Technical practice
How would you design a RAG application using Azure AI services?
What to coverSuggested preparation: Walk through document ingestion, indexing, semantic retrieval, prompt construction, and generation with Azure OpenAI. Explain how you would keep retrieved content relevant and assess whether the answer is grounded in it.
How would you troubleshoot poor retrieval in a RAG pipeline?
What to coverSuggested preparation: Discuss checks for source-data quality, chunking, indexing, and search results before changing the model. Explain how you would compare retrieval approaches using representative queries and relevance measures.
How would you use Azure AI Studio, Azure OpenAI, and Azure Cognitive Search together?
What to coverSuggested preparation: Describe each service’s role in developing, testing, and serving an application, without assuming a particular deployment design. Address how you would evaluate integration choices against application requirements.
How would you build a scalable Python API for an LLM-powered application?
What to coverSuggested preparation: Cover request validation, timeouts, retries, concurrency, and handling model-service failures. Explain how you would balance responsiveness, reliability, and maintainability in a REST API or microservice.
How would you choose and integrate an LLM for an enterprise application?
What to coverSuggested preparation: Compare relevant factors such as task quality, latency, cost, and integration constraints for models such as GPT, Llama, or Claude. Describe how you would test a choice against the application’s requirements rather than assuming one model always fits.
When would you use prompt engineering, RAG, or fine-tuning?
What to coverSuggested preparation: Explain the different problems each approach can address and the effort needed to maintain it. Discuss how you would establish a baseline and evaluate a change before adopting a more involved approach.
How would you evaluate a generative AI application before release?
What to coverSuggested preparation: Define representative test cases and measures for answer quality, grounding, and failure behavior. Explain how you would compare versions and review errors that aggregate scores might conceal.
How would you design and constrain an AI agent or chatbot?
What to coverSuggested preparation: Describe how an agent would choose actions, use available tools, and handle uncertain or failed steps. Discuss when a simpler chatbot workflow might be preferable to a more autonomous or multi-agent design.
How would you monitor and improve an AI application in production?
What to coverSuggested preparation: Cover service health, latency, failures, and changes in response quality, then explain how findings would guide fixes. As an extension based on the posting’s preferred skills, discuss how CI/CD or containerization could support controlled updates.
How would you address security, governance, and compliance in an LLM application?
What to coverSuggested preparation: Discuss access to source content, treatment of sensitive inputs, and controls around model outputs. Explain how you would check that an implementation follows applicable organizational standards without assuming a specific policy.
Behavioural practice
Tell me about a time you translated a business need into a technical solution.
What to coverSuggested preparation: Use a real situation, the questions you asked to clarify requirements, and the actions you took to define a workable approach. State the result and how you checked whether it met the need.
Describe a time you worked across teams on a technically complex delivery.
What to coverSuggested preparation: Set out the situation, your specific actions to coordinate decisions or resolve a disagreement, and the result. Keep your own contribution distinct from the team’s work.
Tell me about a production issue you investigated and resolved.
What to coverSuggested preparation: Explain the situation, how you narrowed down the cause, and the actions you took to restore or improve the service. Include the result and any follow-up monitoring or prevention work.
Describe a time security or governance constraints changed your technical approach.
What to coverSuggested preparation: Use a real situation to explain the constraint, the trade-off you considered, and the action you took with relevant stakeholders. Describe the result without claiming that a particular control applies at Qloron.
