Most recently I asked if the recruiter knew the difference between Java and JavaScript, since he had just mentioned both of them.

"Uh, they're web technologies... in very high demand."

"Yes, but is there a difference between them? What kind of web technologies are they?"

Long pause.

The background silence changes a little, as though a hand were placed over the telephone's mouthpiece.

I can't hear the word in the conversation he's having, but it's clear that he is talking to someone.

The hand goes away.

"Java is a general purpose computer programming language with concurrent objects, and JavaScript is the script version."

Pause.

"Did I get that right?"
