I’m trying to understand the typical career progression within the data science field, but it seems very broad. Can you break down the most common job roles within the data science sector, like entry-level positions all the way up to leadership roles, specifying the typical responsibilities and required skills for each role? Furthermore, could you then outline which industries or sectors are most actively hiring data scientists, and how the required skill sets might differ slightly depending on the industry? For example, how might a data scientist working in finance differ from one in healthcare or e-commerce? I am looking to understand the differences in tools, techniques and the core problems they are trying to solve in each sector.
