Probably Kagi is using candidates as "chatgpt" answers on what they want to further work on for free. I have already suspect this kind of shenigans 2 years ago and stopped my Kagi subscription. As for adverts on positions, ghost jobs likely. That is the current trends. As for Jose, don't be surprised say 3 years from now they contact you. Some companies pool potential candidates like backup boyfriends. I usually just flat out ban this kind of companies and actively spread these companies to my circle to avoid. The lost is really on these companies without further access to specific job pool (and even customers) and of course bad evangelism on their part for decades to come even if they have changed.
This is very speculative so I left it out of the blog post. But... 'market research' is typical endeavour for companies breaking into an unknown space, the decent ones will carry out focus groups with experienced professionals and pay for people's time.
This kind of "do something for X but we won't tell you how!" looks a whole lot like market research disguised as an interview, that way they can do the research for free.
