Google verifies with a third-party background check service, but the service fucked up my resume. I had an employer that had since gone bankrupt (actually, all my employers besides Google have since gone bankrupt), and they couldn't find the business, so they just did the closest string match to the business name, which happened to be a local grocery store whose name was one letter off. Sure enough, I come back as never having worked there, because that's not the company I wrote on my resume, doofus.

It ended up working out because I had previously worked at Google and my former skip-level, who knew me personally, was now the SVP signing my offer letter. But if the hiring process is this incompetent, it makes me wonder how many other people have real career consequences because background check services are lazy and incompetent.
