Google's “Director of Engineering” Hiring Test

Google doesn't ask these types of trivia questions. I don't believe that you were talking to a person from Google one bit.

Everything documented about their hiring practices and anecdotal evidence from people gone through their interview process is that you talk with a real engineer and write code for your interview.

The phone screen is like that, albeit in my case with an interviewer that could adapt a lot more, even if not technical himself.

I took a phone screen interview for SRE (site reliability engineer) at Google Dublin and the questions at the screen test were the same, almost to the word.

I don't know this guy but the questions he's talking about are genuine Google screen questions.

Questions in the later interviews (that is, if you pass the initial screen) are more complex, and involve actual coding or longer problem solving.

It does. I have already said it in another thread, but I have been asked the exact same questions at Google (applying for a Java developer job)

Several other people have come out and said the same.
