Technical practice
How would you approach instruction fine-tuning an LLM for a specific application?
What to coverThe role explicitly emphasizes instruction fine-tuning to improve relevance. Preparation suggestion: explain how you would prepare instruction-response examples, choose a baseline, and compare outputs before and after training.
How would you adapt an LLM to a new domain?
What to coverDomain adaptation for specific contexts is a stated responsibility. Preparation suggestion: discuss how domain data and the intended application would shape your approach, including the trade-off between domain relevance and broader model performance.
Which NLP fundamentals matter when diagnosing an LLM's outputs?
What to coverThe posting calls for a strong understanding of NLP techniques and analysis of model outputs. Preparation suggestion: use a concrete type of output error to explain how input representation or context could affect the result, without assuming a particular model architecture.
How would you preprocess a large dataset for LLM fine-tuning?
What to coverThe role specifies working with large datasets and implementing preprocessing techniques. Preparation suggestion: address data quality, duplication, formatting, and how you would check that preprocessing preserves information needed for the application.
How would you structure and troubleshoot a fine-tuning run in Python?
What to coverThe posting names Python and familiarity with frameworks such as TensorFlow or PyTorch. Preparation suggestion: describe how you would organize data loading, training, and validation, then isolate a problem such as unstable training without assuming a mandated framework.
How would you evaluate whether a fine-tuned model has improved?
What to coverRegular performance assessment and experience with evaluation metrics are stated expectations. Preparation suggestion: explain how you would select metrics for the application, compare against a baseline, and inspect examples where an aggregate score hides poor outputs.
What would you do if evaluation scores improved but model outputs remained unsuitable for use?
What to coverThe role involves analyzing outputs and improving effectiveness in real-world scenarios. Preparation suggestion: distinguish what the metric measures from what users need, categorize the failures, and use those findings to guide another evaluation or training iteration.
How would you decide what to change when tuning model performance?
What to coverPerformance tuning and iterative improvements to training processes are named in the posting. Preparation suggestion: describe a controlled way to compare changes and weigh gains in relevance against training cost and other observed performance changes.
How would you assess one model across applications with different needs?
What to coverThe source describes meeting the diverse needs of various applications. Preparation suggestion: explain how you would define application-specific evaluation sets and decide whether a change helps one context while harming another.
Behavioural practice
Tell me about a time you worked with other functions to improve a model.
What to coverThe role calls for cross-functional collaboration. Use a real situation, your actions to reconcile different needs, and the resulting change or finding.
Describe a consequential technical decision you made for a team.
What to coverThe posting expects responsibility for team decisions and team performance. Explain the situation, how you assessed alternatives and involved the team, and what happened after the decision.
Tell me about a problem you helped solve across multiple teams.
What to coverProviding solutions beyond the immediate team is a stated responsibility. Give the situation, your specific actions to coordinate and resolve the issue, and the result for the teams involved.
Describe a time you mentored a junior colleague in model development.
What to coverMentoring junior team members is explicitly part of the role. Set out the learning need, what you did to support the colleague, and the observable result without overstating your contribution.
Tell me about a time an evaluation finding changed your model-development approach.
What to coverThe role calls for regular assessments, recommendations, and iterative improvement. Describe the finding, the action you took or recommended, and the result, including any remaining limitation.
