Bloomberg Sr Software Engineer interview questions

Recruiter call describing the process. First round video call with two interviews and then another round with two interviews. Didn't make it past that round as they said they would notify me via email.

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
