ProMedia interview questions

After applying, I was emailed to set up an interview for the following day. The interviewer reached out to reschedule shortly before the call due to a meeting, but I never received a call despite having confirmed a second meeting time and sending my number. Many things can come up in work and life, which is understandable, but after sending a follow-up email, I never received a response. Whether one is an interviewer or job seeker, this is not professional or respectful behavior. I hope that she is well and nothing serious came up.
