I scheduled a zoom interview at this company, on the interview day and a day before the interview, I received what I think are automated emails (from calendly.com) reminding me to make sure I get a quiet place, good internet connection, etc. After creating time off my schedule for the interview, I had to wait for the interviewer who did not show up in time for the interview. Eight minutes into the interview time, the interviewer canceled the calendar invite. I then contacted him (the interviewer) to inquire why the invite was canceled and whether or not we will have the call/reschedule it of which he informed me know that the interview was canceled because "I was not fit for the role". I think it is best if you let someone know before so as to avoid wasting someone's time on an interview that will not happen.
