PPD Country Specialist interview questions

I was first sent a quick computer test/questionnaire. They rescheduled the interview twice, both times at the very last minute. It was done over the phone and took over 2 hours. The 1st person got on and asked their questions. I had to wait 20 minutes for the next person to get on the phone. They ended up asking the exact same questions. Halfway through, the 3rd person got on the call (I guess because the second person was late) and they ended up both asking me questions, which was fine, but they seemed very inattentive and I don't think they listened to any of my answers. When I asked about the job position, I found out that neither of them had any experience with it. They were just random people from different departments. It was just a long, unnecessary process that was a complete waste of time. If this is the way the company runs, I don't really want the job. There has to be a better way. Interviews that go on for almost 3 hours are ridiculous.
