Bloomberg Software Developer interview questions

online coding, phone interview, onsite interview. There were two rounds at onsite. In each round, there were two people in the panel. The worst part about the interviewers is that they know only one language which is c++. They have no clue about Java, C#. I was told to solve a problem and write the test cases for it. I gave my best. One interviewer was impressed. The other interviewer seems to be not interested. I gave my best to involve him. Later at the end, while shaking hands, the non-interested interviewer said: "Thank you for applying at Bloomberg". In the next round, I had difficult questions, and it went better than previous and interviewers were very polite and humble this time. The policy with Bloomberg is, if things do not go well in first two rounds, the person Manager who is supposed to interview in the third round, will just come to show the way to the elevator. This is the worst behavior I have experienced in the tech industry. If you are going onsite, prefer to use Bloomberg's travel. After the interview, there is no follow up on reimbursement.
