Air Canada interview questions

They contacted me to set up a time/date for a video interview. That day I was on time, the person on the other end can't heard me and told me to end the call and we can join a new call (they use an app for video calls) I did that, end the call but the person never came back to interview me. I sent an email, called twice and I still have not receive an answer. I think it's disrespectful.

A long day. It’s mostly just waiting in a room with a bunch of other candidates waiting to have your number called in for various stages of the interview. First part is the one on one , second is group interview , and last you wait to be called to be told you’ll get a call back in 2-3 weeks.
