After having the initial phone screening I was scheduled for three back to back interviews. My experience turned sour quickly when I ended up waiting 10 minutes for one of my interviewers to show up and then later excused themself for and addition 5 minutes. Ultimately it felt disrespectful to my time given that I already had to set aside 3+ hours for these interviews.

The recruiter was late and seemed very unsure of what he was speaking of during the interview as they were unaware of the position or role that was being interviewed for

I had a 30 min introductory interview with their recruiter. When I asked more about the job he said, "I'm not sure. That's not my department." I understand maybe not knowing day-to-day tasks, but he couldn't even give me a job description. He then asked me on a scale of 1 to 10 how likely I would be to take the job which I responded, "I don't know because you haven't told me anything about the job." I initially told them I would take the next interview round, which included an excel test, but that initial interview gave me weird vibes. I also don't understand why they have to watch you take an excel test. I understand assigning one but watching you take it seems weird and a waste of time for them.
