Rifeline interview questions

I applied online for this position and was invited to a phone screening a few days later. The first scheduled date was rescheduled. On the second date, the interviewer didn’t show up. Eventually, I received an email saying that the meeting needed to be rescheduled, and a follow-up with a new date and time would be sent. I never heard back. As someone very interested in this position and appreciative of the opportunity to interview, I was completely disappointed in how the interview process was handled. Never received any kind of follow up- which says a lot. Both times, I left & canceled commitments with my current job just to interview for this position and learn more. My time was wasted, and I did not feel appreciated or valued.
