Mostly interviewed about RAG in detail, some probability & resume. 3 rounds with a week gap between each. Overall got the offer but declined it due to getting another one

I appeared for 2 rounds 90 mins each on the same day. My experience with the entire process was not very good. Both the Rounds were Technical. My Second Round went well, but my first round was not great. The interviewer kept interrupting me and would immediately shoot the next question while I was still answering the current one. They did not introduce themselves or talk about the role but directly jumped their horses on the technical questions. I found it quite unprofessional.
