Bloomberg Senior Software Engineer interview questions

I was interviewing for the position in the MARS team. 1st round - 1.5h online screening. 1 hard leetcode problem with a lot of additional questions. 2nd round - virtual onsite. First call - 1.5h coding challenge (another hard from leetcode). Second call - 1.5h system design. Very strange (bad) experience. After I walked my interviewer through my background on system design call he was disappointed and the last hour kinda felt like a waste of time (he wasnt paying attention to my design doing other things on his computer in parallel). On the other hand I really enjoyed talking to all other people in Bloomberg

4 LC questions and 1 behavioral interview. 1/2 easy LC. The rest medium and 1 low Acceptance medium. Then behavior after. Trying to move into a more practical style interview.
