This was a simple phone screen, and it seems the recruiter was not given a good set of questions.
However, I actually doubt it was really a director of engineering screen, despite this person's experience level (maybe it should have been, but ...).
I say this because I know a lot of the leadership recruiters, (it's a separate thing from regular SWE/manager recruiting), and I know how the process works. They don't screen candidates this way normally precisely because it doesn't make sense. (Whatever you may think of Google's regular non-leadership recruiting :P)
Instead, they ask question directly relevant to what the hiring manager wants/needs (IE i give them the questions to use), and in most cases, do just enough to know whether it would be a waste of time for the hiring manager to talk to them. At which point, a hiring manager like me talks to the candidate and decides whether to bring them in for onsites.
This particular set of questions seems closer to standard non-leadership SRE questions.
