Bloomberg Feeds Support Analyst interview questions

I applied online and was contacted for a telephonic interview in July 2014. The telephonic interview was pretty straightforward with few technical questions and resume walk through. After two days, I was asked for a date to come for the in house interview. I gave them a day 3 days ahead in the same week. I received no response from them on the confirmation. After periodic follow up from my side, finally they were able to set up an in house interview for me after 2 months! The recruiter also asked me to prepare a presentation for the interview and informed me that the interview would last for 2 hrs. On the interview day - I was welcomed well, taken to the conference room and was introduced to the other team members in New York via video conferencing. I was then told that the interview could last upto 5 hrs! They asked me few basic technical questions and behavioral questions. After 1.5 hrs, one of the interviewer told me that the other two interviewers are busy and walked me out to the reception where I realized that my interview is all done for the day! They did not ask about my presentation so I mailed it to the recruiter to pass it on to the team. The next day they emailed me that they are not offering me at this time.
