Bloomberg Software Developer interview questions

The nearest interview date was about 3-4 weeks from after I got the interview date. Recruiter was 15-20 minutes late. I was led into a room and interviewed by two more senior engineers for an hour long round of standard interview questions. I had lunch in this room, and some time later two different senior engineers came for the design round. One interviewer (Tom A.) did all the talking, and the other interviewer sat in silence and watched. Tom would ask 3 different questions and then ask you to respond, which I found annoying. Further, Tom asked very basic questions about every little technical detail and asked me to speak to him like he didn't have a technical background (What data structure would you use? What's a hashmap? What's a bucket? What's a hashcode?). This made solving the problem slower, but maybe it was a test for my ability to explain basic things effectively. Didn't get invited to further rounds, which as I understand means you didn't get the job.

Applied online. Got an email asking for an interview and scheduled a time. Interviewer never called and recruiter wasn't responding to my emails. Finally rescheduled the interview. Interviewer called this time. I told him that I was familiar with C++ but I preferred Python. He insisted on everything being in C++.
