I had a 30-minute Zoom interview scheduled with a hiring manager. After waiting 15 minutes, no one had joined the call so I just left. I reached out to the administrator that set up the interview, and he said the hiring manager got pulled into a client meeting. If they don't respect my time enough to even let me know (without me asking) that the interviewer got pulled into something, why would I ever want to work there? Incredibly unprofessional.
