Bloomberg Software Engineer interview questions

Applied through University Career Fair. Got phone interview 1month later. Passed one round phone interview and go onsite few weeks later. Onsite: Offered lunch, HR would lead candidates (a lot) walking around the Company before interviewing. One or two employees would come and pick you up for interview (A general speaking is that if there is only one interviewer waiting for you, you are very likely abandoned). Failed after two rounds interviews. (The full onsite has 4 rounds, first two rounds for tech questions, one round for manager and one round for HR. If you do not preform well, HR would ask you to go after two rounds.)

Telephone interview first and then onsite. The onsite interview took about 1.5 hour, with 3 interviewers(one of them is an observer, he didn't ask any question, and he helped me a lot), and the questions were mainly focused on data structure and memory complexity. If you pass it, you will presumably have an HR interview. I didn't pass the technical round, but the process seems smooth to me, and the interviewers were very nice. I tortured them with my poor coding skills, and I felt sorry for myself and for wasting their time, and I forgot many important things I should've remembered. Don't spend too much time on practicing specific programming problems which is not very useful, and I think one should make sure their preparation covers all the basic knowledge of the language they choose. Anyway, Bloomberg is my dream company, but guess I am not good enough now, and I might try again after I am more prepared.
