Same here - I was recently offered an "interview support" job by one of these body shops in a far away Asian country, which I immediately rejected. The role would've been to help candidates pass interviews using tricks (cheats, really) like the ones that've been brought up in other discussions before.
If you're good enough to pass a senior dev interview, you're probably also capable enough to create some kind of SaaS tool/plugin for applicant tracking systems (or directly in Zoom?) to help employers identify fake/real candidates.
You have potential to make a lot more money catching these bad actors rather than enabling them.
