ADP Data Scientist interview questions

This was a brief Python in person interview with the analytics team's hiring manager, focused on supervised and unsupervised machine learning methods. I got an offer within a week via phone.

Five or six One-on-one with five or six of their team members in Atlanta. Each person pretty much asked questions that made me repeat pretty much the same thing that I said to the last person. It would've been nice for them to have 1 interview to save everyone's time. I felt a lack of respect from some of the interviewers. One person literally pointed to a work experience and said "tell me about -that-. yeah that." I knew that I was not fully prepared for the job, but knew that I could do the job if given the opportunity, considering that this was an internship. I looked online and saw that the people in this department all came from non-cs backgrounds. However, during the interview, they seemed to demanded a lot of CS backgrounds. It sounds as though they're looking for interns to do their full time work. The entire time, it was literally five rounds of interviews, each one-on-one felt like another version of pointing out how I was unqualified for the job. I actually give fault to the person who screened my resume. Why invite me for an interview then acknowledge I do not have skills that you want? Also, I asked if they were looking to keep interns for long term and convert, I got a negative vibe. One of the worst interviews I've had.
