Total Rewards vs HRIS vs Talent Acquisition vs Talent Development

People and HR, for example, is missing key distinctions for types of roles (Total Rewards vs HRIS vs Talent Acquisition vs Talent Development etc) and all jobs lack meaningful distinguishments in levels.

For example, if I want to search for jobs that are VP or Director of People Operations vs just VP, these searches are not intuitive, or seemingly possible without being served up with irrelevant options.
