MDI Management interview questions

I got an email from HR and they wanted to set up a 30 minute phone interview. When the time finally came, they stood me up. I got an email 2 hours later apologizing and that they weren’t even in the office, and asked to reschedule two hours later. I let them know that I had an appointments already and gave multiple different times to interview and they never even responded! This is so unprofessional especially coming from HR. I applied even though they have a one star rating on Indeed and turns out they got that rating for a reason. Avoid!!!
