Technical practice
How would you decide whether an LLM is appropriate for an AI application?
What to coverSuggested preparation: Describe the task, expected outputs, and where an LLM adds value compared with a narrower approach. Explain how you would test output quality and identify limitations before committing to the design.
How would you design a production-ready application that uses a generative AI model?
What to coverSuggested preparation: Walk through the application components, model interactions, and path from user input to output. Discuss how you would validate quality and handle unreliable responses; the posting calls for production-ready solutions but does not prescribe an architecture.
What would you include in a cloud or on-premises AI application pipeline?
What to coverSuggested preparation: Explain the stages needed to prepare inputs, run the model, deliver outputs, and assess application quality. Compare cloud and on-premises choices in terms of operational complexity and suitability for the application rather than assuming a required platform.
How would you integrate an AI solution into an existing system or workflow?
What to coverSuggested preparation: Describe how you would establish system boundaries, input and output expectations, and responsibilities with the teams involved. Explain how you would test that the integration works within the existing workflow, not just in isolation.
How would you evaluate an existing LLM application and decide what to improve?
What to coverSuggested preparation: Define representative tasks and quality measures, then explain how you would compare results before and after a change. Address trade-offs between response quality and practical application constraints without assuming a particular evaluation tool.
How would you diagnose a drop in quality in a deployed AI application?
What to coverSuggested preparation: Separate possible issues in inputs, model behavior, application logic, and integration with surrounding systems. Explain what evidence you would gather first and how you would verify that a proposed fix improves the observed behavior.
How would you use TensorFlow or PyTorch to investigate a deep learning model's behavior?
What to coverSuggested preparation: Discuss model inputs, outputs, and framework-supported ways to inspect or test behavior. Explain how you would distinguish a model issue from a data or application issue; the posting names these frameworks but does not require one over the other.
Which NLP considerations matter when preparing text for an LLM application?
What to coverSuggested preparation: Discuss how text characteristics and preprocessing choices can affect model inputs and outputs. Explain how you would check that those choices preserve information important to the application's task.
How would you develop and deploy a chatbot or conversational agent?
What to coverSuggested preparation: Explain how you would manage conversational context, handle unclear requests, and assess whether responses serve the intended use. Cover how you would test the agent as part of an application before and after deployment.
How would you decide whether a cloud-based AI service fits a proposed solution?
What to coverSuggested preparation: Compare the service with other deployment options on integration effort, control, and operating considerations. Cloud-based AI services are listed as a good-to-have skill, so frame this as a design trade-off rather than an assumed requirement to use one.
Behavioural practice
Tell me about a time you made a technical decision for a team.
What to coverSuggested preparation: Use a real situation to explain the options, your decision-making role, and how you brought the team along. State the result and what you learned; the posting assigns responsibility for team decisions.
Describe a time you worked across teams to integrate a technical solution.
What to coverSuggested preparation: Explain the situation, the different teams' needs, and the actions you took to align an implementation with an existing workflow. Give the result, including any integration issue you had to resolve.
Tell me about a time you mentored a junior team member.
What to coverSuggested preparation: Describe the skill or knowledge gap, the support you provided, and how you adapted it to the person's needs. Explain the observable result without overstating your contribution.
Describe a problem you helped solve that affected more than one team.
What to coverSuggested preparation: Set out the situation and your actions to identify the issue, coordinate decisions, and reach a solution. Explain the result for the teams involved and how you handled differing priorities.
Tell me about a time you improved an existing AI model or application.
What to coverSuggested preparation: Explain what needed improvement, how you established a baseline, and the change you made or led. Report the measured or observed result and any trade-off you considered.
