  1. Build a recommendation system from scratch: data, candidate generation, ranking, evaluation and serving.
  2. Now that it exists, build a conversational interface on top of it, where users ask for what they want in plain language and the chatbot answers with recommendations. Cover how user requests are turned into queries for the recommender, how results are explained, multi-turn context, and how you evaluate it.
