Problem
Scenario
You have worked on an NLP problem where you needed to turn raw text into a usable model input and ship something practical. The work likely involved choices around preprocessing, representation, model selection, and how to measure quality on messy real-world language.
Question
Describe a project where you used NLP techniques. What challenges did you face?
What This Tests
- How clearly you can explain an NLP problem and why it mattered
- Whether you can discuss tokenization and text preprocessing choices
- How you represented text, including embeddings or transformer features
- How you evaluated the model, especially with F1 for imbalanced labels
