I would not say I do the same, but every time I get new certificate or something happen worth of updating CV, when I upload it to Monster, Indeed, ... (logic here - its better to keep it tidy and spend 20-30min monthly then spend days every couple of years) , their algorithm puts my profile on the top. And then the fun begins with tons of insane recruiters who are offering beginner roles, have crazy expectations or similar shait. So, when I filter them down, usually there is one or two offers which sounds OK, so I go to the interviews hoping they will give "offer that cannot be refused" but every time they fail badly.
