Google's “Director of Engineering” Hiring Test

To be charitable here: is it possible that this person did not work for Google? Historically, I've known third-party recruiters play fast and loose with their affiliation with the company they're recruiting for. This literally could have been any recruiter in the Valley trying to feed candidates to Google.

No, I have been asked the same questions by a person with @google.com email address that clearly said he was a psychologist and not a technical guy. His Linked in info at the time was Google Recruiter.
