1. Using Roberta as a Classifier 
 Explain why Roberta can be used as a classifier based on the fact that it is fundamentally an encoder.
2. Comparison of BERT and Word2Vec 
 An NLP-related question was asked to compare BERT and Word2Vec, specifically why BERT is considered better.
3. LLM for QnA on Large Documents 
 How would you enable Large Language Models (LLM) to perform QnA on many large documents? Are you familiar with the concept of Retrieval-Augmented Generation (RAG)?
4. Understanding of Recommendation Algorithms 
 Do you have knowledge of recommendation algorithms? Can you discuss how you would train a recommendation model that incorporates Natural Language Processing (NLP)?
5. Reason for Transition to LLM 
 What motivated you to transition to the field of Large Language Models (LLM), and do you plan to pursue a long-term career in this area?
