Technical practice
How would you turn a business problem into a testable machine-learning hypothesis?
What to coverSuggested preparation: Explain how you would define the decision the model should support, agree on measurable outcomes with stakeholders, and establish a baseline. Describe how statistical analysis and data tests would help you accept or reject the hypothesis.
How would you check data quality across sources and formats for a speech or voice application?
What to coverSuggested preparation: Discuss checks for completeness, consistency, labeling accuracy, and mismatches between channels or formats. Explain how you would trace a quality issue to its source before using the data in a model.
When would you consider GPT, a VAE, or a GAN for a generative AI problem?
What to coverSuggested preparation: Compare what each approach generates and how its training and evaluation differ. Tie the choice to the problem, available data, output quality, and operational constraints rather than treating the models as interchangeable.
How would you design and test a prompt strategy for a generative AI application?
What to coverSuggested preparation: Describe a repeatable way to compare prompt variants against defined output criteria and representative inputs. Discuss how you would diagnose inconsistent results and decide whether to change the prompt, the surrounding NLP workflow, or the model.
How would you apply NLP techniques within a generative AI workflow?
What to coverSuggested preparation: Explain where text processing or analysis could improve inputs or help evaluate outputs. If discussing a tool named in the posting, such as SpaCy, NLTK, or Hugging Face, make clear what task it would serve and how you would check its effect.
How would you evaluate whether a generative AI solution supports business decisions?
What to coverSuggested preparation: Distinguish model-output measures from the business outcome the solution is meant to improve. Explain how you would inspect errors and use visualizations to communicate results and limitations.
How would you improve a generative model that is accurate but too slow or costly to scale?
What to coverSuggested preparation: Start with measurements that locate the bottleneck, then discuss possible model, inference, or pipeline changes. Explain how you would verify that efficiency gains do not undermine output quality.
How would you design a production-ready AI application pipeline for cloud or on-premises deployment?
What to coverSuggested preparation: Cover data flow, model integration, testing, monitoring, and how failures would be detected and investigated. Compare deployment options against the application's operational needs without assuming a particular cloud service is required.
How would you structure and troubleshoot Python code for a deep-learning application?
What to coverSuggested preparation: Discuss modular code, appropriate data structures, tests, and reproducible experiments using a framework such as PyTorch, TensorFlow, or Keras. Explain how you would isolate whether an unexpected result comes from data, training, inference, or application code.
How would you assess a new generative AI technique before adopting it?
What to coverSuggested preparation: Describe how you would compare it with the existing approach on relevant quality, scalability, and efficiency measures. Explain what evidence and documentation would support an adoption decision and a reusable development practice.
Behavioural practice
Tell me about a time you aligned an AI project with differing stakeholder goals.
What to coverSuggested preparation: Use a real situation, the actions you took to clarify requirements and define success, and the result. Distinguish your contribution from the team's work.
Tell me about a time a data-quality problem changed your approach.
What to coverSuggested preparation: Describe the situation, how you identified and addressed the issue, and the effect on the work. Be specific about what you checked before trusting the data.
Tell me about a time you collaborated across research and development roles on a model or prompt approach.
What to coverSuggested preparation: Give the situation, how you worked through differing technical views or evidence, and the result. Explain how the collaboration affected the chosen approach.
Tell me about a time you explained a complex AI result to a non-technical audience.
What to coverSuggested preparation: Describe the audience and decision at stake, how you adapted your explanation or documentation, and the result. Include how you communicated limitations as well as findings.
Tell me about a time you improved a development practice while managing your own work.
What to coverSuggested preparation: Use a real situation, the standard or workflow you helped improve, and the result for collaborators. Explain how you balanced independent progress with feedback from the team.
