I don't use this in my interviews, and I'm surprised everyone took this literally given that we have a weekly blog article about the villainy of technical interviews and how they destroy the very fabric of software development. I'm using a hyperbolic example to demonstrate what I perceive as a negative trait; A reach for unnecessary tooling to solve simple problems. My hiring experiences have pointed towards it being indicative of a comfortable one-trick-pony.

Likewise. However, if I'm hiring someone for a back end role, I'd expect them to be able to know basic SQL and not just their language's ORM. I'd expect them to be able to type `cd` and not just navigate through their IDE. I don't think there is anything different between that and the relationship of jQuery/angular and vanilla js. jQuery isn't written in jQuery. Debugging rarely stops at the script tag/require statement.
