Aunalytics interview questions

I am appalled at my experience with this companies hiring process. My phone screening (the 1st interview) was rescheduled 3 times THE DAY OF THE INTERVIEW. I was told to call the number of the interviewer at my scheduled time. The first reschedule they told me a few hours before but on my second reschedule my scheduled time came around and I called the number twice, texted the number, and sent an email with no answer at all. About 20 minutes later I receive an email saying they need to reschedule again and this was an "HR scheduling error" and this would "not happen again" and "we are so sorry". My third reschedule comes around and I call the number twice AGAIN with NO ANSWER. This whole experience has been extremely unprofessional and disrespectful. I advice anyone to not waste their time applying to this company.

A phone interview to go through my resume experience. I thought I had met the entry-level position's requirements because hr told me I would get a case study challenge in a few days. But I never got one, had reached out twice but got no response.
