Branch interview questions

My recruiter screening was abruptly cancelled day of (I think the recruiter was let go) so hiring manager rescheduled initial screening. He was warm and painted Branch as a very mission driven, collaborative organization. The second round was a case assignment. After spending a considerable time working on it, I was sent an email 2 days after submission that I was rejected. Asked for feedback and didn't get a response which was bad practice since I prepared to present it to the Marketing team.

The interview at 5 stages I think. I was told the second stage would be a technical question and answer phase, with a no code algorithm question. We took alot of time on the technical question and answer phase, which I answered 90% correctly, then 10 mins to the end of the interview, I was told I would be given a leetcode algorithm question to solve with code. I was dissapointed
