Bloomberg Senior Developer interview questions

Headhunter reached me at LinkedIn and after 2 weeks I had phone interview at Bloomberg. I knew I failed the interview in the first minute after interviewer called me. He called me at cell phone with the Cisco table phone at meeting room. The sound was very noisy and distorted. I'm not native English speaker and I wasn't able to understand him more than 30% of what he was saying so most of the time I was focused more on what he was saying than on solving a problem. + The interviewer was polite and helpful. + the position looks very interesting. - They should use Skype or other voice software instead of cell phones.

Was reached out by a recruiting company regarding an opening with Bloomberg. Since it was through a recruiting company they were able to pass my resume to the team and then decided on a Date/Time for a phone screen interview. I personally felt they interviewer was very rude and arrogant. More than once, he tried cut me and was not ready to hear what I had to say. Twice I wanted to take a different approach and he said not to do that. I get it that he might be wanting to check my coding skills. After I coded he got back to me saying that, earlier you were discussing something about HashMap. Now you can describe it. I knew I was not going to pass this within 15 minutes because he was not ready to listen to an explanation. IMO, An algorithm can be implemented with multiple time complexities. The end goal is to optimize it to the best possible time complexity. When I tried to explain the interviewer was not ready to listen what I was trying to say. Why I choose one data structure over another. Interview lasted for around 50 minutes. In the last 3 minutes, he asked that if I had any questions for him. I asked a few about the team and work he does. He mentioned that he owned a part of the code. I guess, arrogance come with position and money. The only reason I call this interviewing process to be negative is the way the interviewer behaved. IMO, there is no need to pull ranks on interviewees. In an interview, it is the interviewee who should share his ideas and describe successfully why he chose that solution or not. If the interviewer cannot put the interviewee at easy, then it is OK, but at least don't raise your voice. P. S. There are multiple websites where candidates discuss interview questions. I checked. My answers were to the point. I also described the solution and time complexity (twice), but the interviewer kept telling me I was wrong and assume that it is what he says.
