Probably. I would argue that showing up extremely late for an interview that you scheduled is considerably more jerk-ish.

It also wasn’t passive aggressive, or at least it wasn’t intended to be. I actually wanted to know if that was just a thing that was common in the company so I could plan accordingly.

Didn’t your momma teach you that two wrongs don’t make a right??

If someone is a jerk to you, and then you’re a jerk to them… you’re still a jerk.

Asking that question just signals that you don't obey social cues.

Most hiring managers won't like this, as they don't want to be responsible for hiring someone volatile like this.

I think the only place you could get away with this is if you're interviewing with a C-Suite member who has nobody to answer to.

Saying something like "Actually, I felt it was unprofessional and disrespectful to not have the interview start at the agreed-upon time" would also be direct, no? The way it's written sounds way more inflammatory.
