Most job ads - especially in the tech industry - are already basically fake news, aren't they?
"It's all about the funnel! Got to get more people in our hiring funnel! But wait, we don't actualy know how to evaluate them effectively and efficiently (or even how to communicate with them decently). So... let's just get a bunch of people "engaged" and see who washes up at the end. That way, we can at least tell the higher-ups that thanks to our diligent hiring process, we can go online and brag about how we only hire the top 2 percent of incoming candidates."
