Dell Technologies Senior Advisor interview questions

I was called by phone to schedule an interview, we scheduled it for the next day. The interviewer sent an email 15 minutes past the interview start time saying she was out sick and we rescheduled again for the next day. The next day, she was a no-show with no explanation given. I find this very unprofessional, and I withdrew my application. Very disappointing from a large and well known company.
