Google's “Director of Engineering” Hiring Test

FWIW: As a director of engineering for Google, who interviews other directors of engineering for Google, none of these are on or related to the "director of engineering" interview guidelines or sheets.

These are bog standard SWE-SRE questions (particularly, SRE) at some companies, so my guess is he was really being evaluated for a normal SWE-SRE position.

IE maybe he applied to a position labeled director of engineering, but they decided to interview him for a different level/job instead.

But it's super-strange even then (i've literally reviewed thousands of hiring packets, phone screens, etc, and this is ... out there. I'm not as familiar with SRE hiring practices, admittedly, though i've reviewed enough SRE candidates to know what kind of questions they ask).

As for the answers themselves, i always take "transcripts" of interviews (or anything else) with a grain of salt, as there are always two sides to every story.

Particularly, when one side presents something that makes the other side look like a blithering idiot, the likelihood it's 100% accurate is, historically, "not great".

This looks like a typical pre-interview recruiter phone screen… they're looking for shibboleths that identify the candidate as a genuine computer person who took CS 101, and exclude candidates who spam every job with bogus CVs. I'd start every candidate with this screen, unless I personally knew them & was familiar with their technical ability.

They'd be internal to recruiting, so you wouldn't see them unless you were heavily involved (doing interviews and recruiting trips isn't being heavily involved). They're for any recruiter to use to quickly eliminate bogus applicants.

You can just outright call him a liar… I'd expect this to be a fairly accurate report. It looks like the recruiter misused the screen; instead of eliminating obviously bogus candidates, they used it to eliminate a candidate who may or may not get an offer (and thus a commission). They should have proceeded to the technical phone screen stage. If the guideline on the recruiter screening is: drop anyone with <100% correct, then I think that's silly.

I'd hope it's not too typical, since four out of the ten official answers are wrong, and even one of the questions manages to be wrong. (Specifically, the "why is quicksort the best?" is just completely ridiculous.)

It's one thing to blindly apply a simple questionnaire without thinking about the answers that come back, and yet another thing to do it with a questionnaire that's doesn't even get stuff right.
