TD Product Owner interview questions

HIRING MANAGER DID NOT CALL ON THE DAY OF INTERVIEW I applied on TD website. On Friday evening I received an email directly from the hiring manager with phone interview schedule for Wednesday the next week. I confirmed it and on the day of interview I waited for 20-25 minutes for the call and he didn’t call at all. I followed-up on email twice but no response. Very unprofessional of an INTERVIEWER to not call the candidate at all and not even reply on email. It’s a shame how they treat such highly experienced professionals and not value the candidate’s time.
