Probably not, but you should always assume that if they have the capability (and they do) that they will 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 their 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.
