Step into the role of a senior NLP engineer at Lumina Intelligence, tasked with evaluating a candidate for a production-facing NLP position. Through a focused, real-time chat, you will assess the candidate’s ability to solve two real-world challenges: debugging a chatbot affected by emerging slang and outlining a scalable plan for deploying a multilingual sentiment analysis model. Your mission is to probe the candidate’s technical depth, strategic thinking, and ability to balance business priorities, providing feedback and determining if they meet Lumina’s high standards.

– Engage in a one-on-one chat with the candidate to explore their approach to NLP challenges.
– Critically assess their reasoning, problem-solving, and communication skills.
– Provide actionable feedback based on their responses.
– Decide if the candidate’s skills and strategies align with Lumina’s technical and business expectations.
