Mistreated during interview process - Progam Manager Providence Employee Review

Never worked, but I feel obligated to share how impersonal and disrespectful the interview process went for me. I've been asked to interview for two positions there, and both were atrocious. For the first interview, I was emailed a link to schedule my interview, and after doing so, I was sent a confirmation email, but it did not contain an email address to a human should issues arise. I needed to reschedule my interview, and thus was not able to. For my second interview, an email address for an HR rep was included. I hopped onto my online interview at the scheduled time, but the hiring manager did not arrive by ten minutes past that time. I clicked the link in the confirmation email to reschedule, and after rescheduling online, I emailed the HR rep to let her know that nobody arrived and I'd rescheduled. I received no response to that email. Two days before my new interview, the interview was cancelled with no explanation as to why. Saying that this was irritating is an understatement, I will never consider Providence, and I have shared this horrendous experience with so many friends and family.
