This monster.com article picked a terrible example, since the person complaining on Business Insider wasn't so bright. But there's plenty of other articles out there to choose from if you're looking for critiques of the Google hiring process.

In my personal experience, Google was weak on follow-up and internal organization: "we'll get back to you in a week" was actually five weeks, and three months after that a different recruiter called me up to interview for the same job. I came away feeling like they didn't have their act together.

Of course, this was a few years ago.
