I don't think the rank of the position matters - it is unprofessional to not show for an interview, regardless of role, and leaves an appropriately bad impression on the candidate. In a previous role, I would go on campus recruiting trips for my company, and we'd often have back to back interviews. Even when the I was literally trapped in a room, so the candidate knew I was there, I would do my best to finish on time and quickly get the next candidate. Eventually, our recruiters started building in buffer time, but until then, if I wanted to present myself and my company in the best light, then we had to start on the right foot - on time. I occasionally interview higher level roles these days, and it's the same thing. Being virtual makes it far easier, since I can go from any meeting to the next with a button click, but when we were doing in-person interviews, it was necessary to plan for travel time between rooms. In the best of cases, the interviewers were the ones who moved, and not the candidate, but in either case, I'd rather wait on them than they wait on me. So, no, it's neither normal nor professional.
