GLG Analyst - Primary Research interview questions

It took almost 10 days. Initially there were 2 telephonic rounds just to assess the communication skills. I was then called for a face to face interview at their office in Gurgaon. 3 interviews were taken and none of them was technical. They only asked one single question, Why GLG". After that I was given a case study and made to write an email relevant to the profile. The next day, another telephonic round was conducted and I was given a very positive feedback. They called me again to their office for another round of F2F interview. The regional and the country head interviewed me. As soon as I reached back home, they called me and said that they consider me fit for the post of Compliance analyst so they want me to have all the previous 10-12 rounds again with another team. However, they did not disclose the results of my earlier process. After I declined their offer, the HR called and said that they are hiring only experienced candidates for the first profile so they won't be selecting me. I was actually very angry as I had already mentioned to them during the first round that I was a fresher and they had confirmed that experience was not required for that particular profile.
