Gartner Marketing Associate interview questions

The beginning of the process (essay questions, 30 minute phone interview) went very well. I had a nearly 4-hour in person interview, which also went well but was very repetitive. I met with about 5 different groups of people who asked nearly identical questions - it was a test of endurance as much as intelligence. After this interview, the process dragged on, and I had another phone interview. I was very confused about how a 10-minute interview would help them make their decision after such a long face to face interview and a very comprehensive process in general. It was clear they couldn't make up their minds and at this point I had already decided I did not want to work at a place that could drag out an entry-level hiring process for 2 months and keep a prospective employee waiting and waiting for an answer. Since they are still hiring for this position 3 months later, I see not much as changed.
