Bloomberg Financial Sales & Analytics interview questions

Passed the first interview and was invited to a second interview in their headquarters. I was given the names of my interviewers so I prepared considering their personal interests but completely different people came up and they had me sitting quite a while to find a room for my interview. The interview was not so good or bad but the interviewers seemed very uninterested and bored of the situation. Maybe it's me that was the problem. However, did not get the offer. Also, they didn't pay me the transport nor hotel bills they promised me in the early meeting.
