At the same time, the goal of dark patterns to to make people spend more money. Given that revenue is very likely one of the key things Google wants (and thus promotes) out of apps, its also entirely expected that the apps people find are largely those who try and get the most money from users, which requires dark patterns.
Tech, from my experience, has a lot of job postings, but its very difficult to actually get an interview nonetheless a job. I’m not entirely sure why its so difficult, as there does seem to be a pretty big need for it across the board. My best guess is mix of companies needing employees but not being willing to hire/train them leading to “fake” postings (alongside those just meant for data collection), and just a generally competitive market right now.
