Epic! interview questions

I applied on LinkedIn and when they reached out to me the only scheduling availability they had was nearly a month later. I asked if this was a mistake and was told that it wasn't because the interviewer was going on vacation. I scheduled the appointment anyway. When the time came they were nearly ten minutes late, asked me questions that felt like they were given a list instead of being told what the role entailed. As I got into answering her questions, suddenly the call ended. They rejoined to say they were having technical difficulties and rescheduled for the next day. The next day the interviewer was late again and asked me questions that I had answered the day before. After their questions they asked if I had any but I didn't feel confident in their ability to answer them so I didn't ask. Two days later I got a rejection email. Overall, it was handled very sloppily and unprofessionally.
