Point being, I can just about guarantee that your data is in these systems. It's probably being used for targeted advertising, recruiting tools, etc. And I wouldn't be surprised if half the data tied to your name is wrong (it was for me when I looked myself up).
tho, i was just thinking about a typical fortune 5000 company -- e.g. a FAANG, etc.
they have their big, elaborate HR ATS systems - like iCIMS - presumably the data they collect are for any number of things - but is the info sold, to a data broker or advertisers or marketers or etc.?
