Probably not, but you should always assume that if they have the capability (and they do) that they <i>will</i> do the least intrusive thing they possibly can (it can't be the most intrusive thing because of a public relations nightmare scenario also because that would raise their risk too) to minimize <i>their</i> risk. I'm talking about a system that gives some sort of score to a candidate based on whatever Google can find on- and off-line about that person (off-line through their partnerships... for example banks, social networks, internet service providers, etc.) I am only speculating but I wouldn't be surprised if they did something like that in certain markets. Anyways, always assume the worst when it comes to Big Tech. Data is the New Oil as they say.
I don't think recruiters have access to such a stuff.<p>If they did, that would be huge issue imo.<p>But I'm only guessing, not a Googler, so.
I assume they do use your search history for some purposes.
For instance I have been enrolled inside the Foo Bar challenge from Google, and from my deductions it is thanks to my search history (mainly programming-related).
The Foo Bar challenge is a suite of tricky programming questions and in the end, some of the winners of the challenge receive a message from Google's recruiting team (as I did) where it can lead to a job at Google.<p>This is only my deductions from my experiences with Foo Bar, it might only be in that case, I am not exactly sure, but you should assume they do.
