CME Group Project Manager interview questions

Was called by a recruiter from the CME Group, discussed the position and my background and my availablity for a phone interview. I went through the 1/2 hour phone interview with the manager of the group, went well. I came in for the interview with the manager and 5 other people, which took about 3 hours. Some of the people were laid back and some were very judgemental and rude. The huge disappointment was that I followed up with the recruiter and the manager and never heard back, which I found to be a bit unprofessional and arrogant. From reading other comments, that seems to be there MO, which is quite inconsiderate. I actually found I didnt get the job because someone else updated there linkedin with the job title.
