I’ve worked on something similar in the past & was looking at how many jobs (even promoted ones) were listed on some sites.
It was for web3… what I discovered is that these sites mostly take jobs from other sites and just post on theirs… One of the people in the space even said that he does that and after 12+ months he’s still trying to be profitable after paying for bubble, apps, etc.
Not trying to discourage you but that was my finding about 3 or 4 months in with a community of 500+ people on Discord, looking to find a job in web3.
Most of them were from 3rd world country, probably just looking to take any job that they would get - so the few serious companies I actually got in contact with immediately turned them away. I even tried negotiating for an internship, but it didn’t work.
