Multivac Accounts Receivable Analyst interview questions

I was contacted by HR in Sept of 2018 through email and asked to book a phone interview. I booked the interview and when the time came they never called. I called the HR representative's direct line and left a voicemail stating that we had a phone interview scheduled and confirmed my number. I also sent an email after it was clear they weren't going to call back. 11 days later I received a reply and was asked to set up another phone interview which I did. They ghosted me on that one, too. I was shocked.
