if I was 5 minutes late to an interview it would ruin my chance of getting the job. but if an interviewer is 5 minutes late I’m suppose to be okay?

Today it happened again where an interviewer was 5 minutes late. I left the zoom call because I don’t understand why I should be okay with lateness. when it would 100% not be okay for a candidate to be late If i’m expected to be early then so should the interviewer.
