Bloomberg Senior Software Engineer interview questions

Recruiter screen, then technical screen where I was asked LC242 (valid anagram) and solved it. Setup the virtual onsite which was 1 technical, 1 "system design" (not really), 1 manager, 1 hr screening. So I show up to the technical interview and the interviewer asks me questions about previous projects for the first 20 minutes... Then I solved LC20 (Valid Parentheses, with a twist) and with about 18 minutes left in the interview, the interviewer just says "yea I don't feel like asking another question".... Okay? Same thing for the system design interview, first 20 minutes are the interviewers asking questions about my previous projects. Then, the interviewer took 10 minutes (not exaggerating) to introduce the challenge which realistically could have been explained in 2 minutes. So, I was left with 30 minutes to solve the problem. I started to lay out high-level system design and the interviewers pretty much immediately wanted me to go into database design + schema. That's most of what I talked about and then it ended. They didn't seem interested in normal system design topics, they just wanted to see how you'd design the DB. I just feel like the interviewers shouldn't be asking questions for 20 minutes in the beginning. I also think they should call the system design interview something else because it's not system design, it's DB design. Overall, was not impressed with the interviewers during the virtual onsite.
