About the role
This interview covers building language systems from data definition and baselines through evaluation and production. The panel is looking for disciplined error analysis, awareness of varied language use and engineering judgement beyond simply selecting a large model.
How to prepare
- Prepare one NLP project with the task definition, data choices, baseline, evaluation and deployment constraints.
- Revise classification, retrieval, sequence labelling and language model evaluation at a practical level.
- Practise explaining why an aggregate metric can hide important failures across language or intent groups.
- Think through annotation guidance, disagreement analysis and representative data collection.
- Be ready to compare quality, latency and cost options for a production language feature.
Common mistakes
- Choosing a model before defining the task, baseline and meaningful evaluation slices.
- Reporting only one aggregate score without inspecting costly or under-represented errors.
- Assuming informal or mixed-language text is merely noise to remove.
