Bloomberg Senior Software Engineer interview questions

The first round was a technical phone screen in a shared coding environment on hacker rank. It involved two leetcode easy problems: determine if two BSTs are equal and calculate how much tax a person would need to pay for the year. It went well and I got along with the interviewer so I was scheduled for a virtual onsite which I was told could take up to half the day if I do well on the technical portion. Before the interview I had a call with the recruiter where he gave me a very high level break down of what to expect and some tips. Bloomberg likes to keep things flexible so they can move interviewers around if needed so he couldn't give me any detailed information like what I would be tested on or who would be interviewing me. This ended up working against me because from other glassdoor reviews for this role (as well as other technical interviews in general), it seemed I would be getting leetcode style algorithm questions in the technical portion and potentially a system design question in the non-technical portion. So I focused the majority of my time practicing algorithms and brushing up a bit on system design only to be given two questions which were a hybrid of design and coding. I was unprepared but I worked through the first round. Then in the second, my nerves got the best of me and I froze up on a trivial detail. After I got through it, one of the two interviewers cut the interview short and I got the impression he felt this was a waste of his time. From my conversation with the recruiter I knew if I didn't do well in the technical portion the day would get cut short so I was glad to meet another engineer in the third round but it quickly became clear he was just talking to me as a courtesy as he didn't present a problem and simply asked if I had questions about Bloomberg. To be fair, asking him questions and hearing about his experience at the company was useful and made me interested in the company but he was also candid about the downsides which I appreciated. After two business days I received the rejection email and I haven't heard from the main recruiter I had been in contact with since.
