Bloomberg interview questions

Recruiter screen and then call with the hiring manager. Recruiter didn't understand the roll so I prepped wrong for the HM call, and it showed in my call with the HM. The HM didn't introduce herself or even so much as ask me how my day or week was, just jumped right into questions. She spoke so quickly that I had to ask her to put one question into the chat. At the end of the interview she made it clear she didn't want to answer my questions and said "thanks for your time, it's been - uh - interesting." At the level she's at, this was uncalled for and disrespectful of my experience. Why waste my and Bloomberg's time if you're coming into the interview with a huge chip on your shoulder?

The process was pretty lengthy, consisting of two coding interviews, two system design interviews, an HR round and a final manager interview. During the coding interviews, the interviewers were not too algorithmically strong, having understanding difficulties with well-known algorithms. The system design rounds were interesting, but in the end, after my final interview, I found out that they don't appreciate at all asking questions and having a dialogue, but they just want to hear a final architecture, without discussing in depth about different scenarios.
