Bloomberg Sr Software Engineer interview questions

One recruiter had connection with the hiring manager and forwarded my resume. The first phone interview went well and the interviewer was very nice. Right after the interview, the recruiter received positive feedback and told me that they invited me for in-person interview. However, the next day I was told there would be a 2nd phone interview because I am not local. Then the story came. For twice they didn't call me at the scheduled time, each time they had different reasons. The third time I finally received the call after waiting for another 20 minutes. This time, the interviewer asked some weird questions and wasn't nice. I got declined quickly.
