I had an interview with the hiring manager, a couple of hours after that interview the hiring manager reached out for availability to get scheduled with another member of the team. Day of that second interview, the interviewer did not show up. Reached out to the hiring manager who didn't respond until a couple of days later asking if I ever got connected with that interviewer, when I told the hiring manager no, we never got connected, I never heard anything again. Completely unprofessional.
