Purolator interview questions

Notified multiple times through text and email of the virtual interview time. I logged in for the interview 10 minutes early and was notified that it was a queue and that I would be asked to join a room within 15 minutes. 5 minutes later, I received a text that the room was ready. Upon entering the room, I received a notification that the recruiter would join me shortly. I waited for half an hour. At that point, I exited the room. This is rude, disrespectful, and wasteful of the candidate's time.

The first interview was over the phone with a HR talent acquisition, the second one was an interview in person with a panel of three people, and lastly a third panel interview with two people.
