Gartner LCP interview questions

Lengthy interview process, first speak to Recruiter Assistant, then Recruiter, then two Associates and then 2 managers (over 2 months). I was told at each stage that I asked good questions and was well prepared. I did a lot of research on Gartner and felt confident in the interviews. I was very disappointed when I got an email saying "thank you but they decided to pursue other candidates at this time."
