Yoh Senior Recruiter interview questions

Extremely unprofessional. I was reached out to by one of their recruiters for an internal role. About a week later I was asked on a Friday my availability to interview that day itself. I never heard back until the end of the day where I was told the interviewer was too busy and asked for my availability the following Monday and Tuesday. I never heard back until the end of the day Tuesday where I was told the same thing and asked for my availability for Thursday and Friday. Of course I never heard about an interview on Thursday or Friday. Another week went by where I heard nothing, and then I was asked this following Monday my availability for this week. Of course I never heard back about an interview which brings us to today.
