So, while looking through the Data Analyst interview prep course. I saw a question in the experimental design section asking about song recommendation model. I am confused because throughout the data analyst career path, I did not learn anything about machine learning models or recommendation systems. So why in the Data Analyst path, I am seeing interview questions about that? I am trying to create a distinction between data scientist interview questions and a data analyst interview questions. Because recommendation models should be in the data scientist interview, I am not sure why it is listed in the Data Analyst interview. Unless data analysts get tested on that(recommendation models), but if that was the case, why wasn’t that taught in the Data Analyst career path? I am just trying to figure out if I need to learn recommendation models to be a Data Analyst because the analyst I am aspiring to be is the one that use descriptive statistics and summarize past data to find trends, not the machine learning type and that is why I did not do the machine learning specialist path, I did the analytics specialist path.
