Yes they did that, but they had scheduled me for 9-5 on the day of the interview, which doesn’t entitle them to waste my time by having one unprofessional interview session followed by me sitting for 45 minutes and being told I can go. I could have scheduled other things or planned my time differently if I had known it would only last ~90 minutes, or even that it lasting less than the full 9-5 based on realtime decisions was a possibility (it was not described as a possibility).
