Your question is Discuss Practical NLP Experience. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You have worked on systems that process unstructured text and turn it into useful signals for downstream applications. The interviewer wants to understand which NLP techniques you have used in practice and how you think about applying them.
What experience do you have with NLP techniques?
