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".

So you're saying Google's recruiters don't tell what position they are interviewing for and that they found a 20+ years experienced engineering manager holding patents on computer networking under-qualified for an ordinary site maintenance position. Well, that sounds like a dumb recruitment process.

This to me looks like an initial phone screening interview. It's not actually a "technical" interview (there is no code to write and the person that interviews you is a technical recruiter and not an actual engineer). As far as I know (I might be wrong so take this with a grain of salt) your first screening interview is usually used to decide in which direction you want to proceed (for example if you want to be hired as a SWE-SRE or SE-SRE position). It's not far fetched to think that they were just applying some standard questions without having an actual clear position in mind yet.

I also agree with the grandparent, I'd be very sceptical about this transcript being 100% accurate.

This.

I passed several rounds of interviews at Google over a number of years (phone screening, phone interview, on-site). This is definitely a phone screening, where the recruiter expects "standard" answers to "standard" questions. Remember that interviews are somewhat of a game. Trying to be smart at this stage is the wrong move.
