This response doesn't seem warranted. GP didn't say you're his monkey. He said the job gets boring. Candidates with good people skills get hired more often because they bring a little more joy to the workplace. And, all other things being equal, that decision makes perfect sense.

Shots fired, haha :)

Just to make sure you see it I’m copying some things I wrote to other replies:

1. Charisma is a plus, but how much depends on the role, and for most roles it’s not going to matter.

2. To be clear, most interviews are interesting and enjoyable, even the sessions I’ve done a hundred times. But, just being realistic, neither I nor the candidates are always on our A game, and sometimes the result is a quiet and dull interview. And to be clear, that may still result in an offer recommendation! Some of these interviews are dry because the candidate knows the material down pat, doesn’t want to chit chat, and has no questions. Those are, in fact, the very kind of person I imagine would improve their performance by smiling and asking what I had for lunch :)

When I was reading that comment it seemed like a lighthearted question was a plus if it happened, but obviously not a serious metric that anyone is tracking.

I don't know why commenting and replying has to necessarily be so hostile and adversarial.

Just because guy characterization something boring and repetitive absolutely does not imply he wants to entertain you. Such implication is illogical.
