Well in academia, and generally in research, interviews are about 1.5 days of solid interviews, plus an hour presentation. In normal times, add a good dose of jetlag.

I once interviewed at a place that was almost two solid days of 30 minute interviews, one after another. By the end of the second day I completely didn't care about anything they wanted to ask about or what they thought about my responses. I think this stamina crushing test was actually part of the evaluation. Not kidding about that.
