Gartner Associate Client Partner interview questions

There have been quite a few interviews (5 I think) back when I applied in 2009 and the whole process must have taken a few months. Good solid interview process. Very clear at every stage of the interview process. The first interview was over the phone with an internal recruiter which must have lasted c. 30 minutes. The second stage was a face to face interview with the team manager recruiting for this role. This was conducted in person in Egham and was a very pleasant experience. The manager was very friendly and asked me a lot about my previous experience and how it can benefit Gartner's role she was recruiting for. The next stage was a phone interview with the VP of Service Delivery for the whole group. The last stage was a 2-hour panel where I was asked to prepare and deliver a presentation and answer all questions that they had in the meantime and afterwards. There were 3 senior managers present at that interview (out of 5-6 participants who were supposed to be there but could not due to holidays etc).
