No, I think there is justification. In the real world, people aren't stoic and patient, especially executives who have their day planned out to the minute. The applicant did everything right here, and I'm not defending the interviewers, just trying to think about how that situation comes about. If the applicant was on time, would the interview have gone the same way? I don't think so.

You're conflating explanation with justification. Being a pissy asshole like described is explanable, but not justified: it betrays a deep lack of professionalism, and is a giant black mark on the interviewer.

Equivalent situation: If someone turns up 30 minutes late because they wanted to catch a couple extra zs, that's also understandable, but is just as unjustified and makes them just as much a jackass.

As professionals, we are called to treat everyone with dignity and respect, no matter what bug happened to crawl up our ass this morning.
