Bloomberg Senior Software Developer interview questions

Had interview with them few weeks back My first round was simple DS/C++ problems 1. How to get top 10 most traded stocks from continous feed of stock trade 2. Implement a function so that it will not proceed with its operations if it is called more than 100 times per minute Second Round 1. Implement Shared pointer 2. Design a Web Service, where multiple feeds are input and they are trying to modify a common database Third Round They showed me Bloomberg Terminal. Asked very generic questions what were the most challenging moments in your career. How do you plan your work? Few questions around the background. After this I met with HR and he said entire team is really positive about me. Fourth Round Interview with the senior manager. Showed me Bloomberg Terminal again, I kept asking him all the queries I had around the terminal. In the end he said you asked really good questions HR Round He said people are very positive. Discussed salary expectation and all the benefits Bloomberg provides. Round with Head of the Business unit He was not sure that I had all the technical rounds before and asked me very basic programming questions 1. Error in the code 2. Difference between 32 bit and 64 bit systems Few behavioral questions, Why Bloomberg? Why we should hire you? After this HR told me that people were really positive and he will send me salary breakup next day. I didn't received any confirmation from them for a week and later found out that I was not selected. This is really unusual of Bloomberg as they respond within 2 days. I answered their each and every technical question, I really don't know what they expect. Overall a good company with weird people.

Applied online. After ~3 weeks received request for phone screen. Phone screen lasted ~1hr and was all trivia on C language, with questions on keywords, and analyzing a few lines of code. Interviewer did not show any emotion or give any indications of whether or not they were satisfied with a given answer. Asked some Unix questions and trivia on threads, parallel processing. Ended with some open ended questions on data structures, like 'are you familiar with any data structures?' I mentioned linear structures (array, LL, etc), hash tables, and trees to give a couple examples. Asked questions like 'what is notable about XX data structure,' 'what is important when hashing keys', 'how are trees balanced.' I had a lot of questions and the interviewer said 'I can give you about 2 minutes.' He sounded like a robot, so I asked if he enjoyed the job and he said it's fast paced and you will roll out features often.
