Three out of the four rounds were normal. The first round was an algorithm question, it was more of a "practical" type of question than some leetcode question. The seconds was a system design question which was like any system design question vague so nothing new there. Third was exec chat which felt unnecessary. The fourth and last one was another algorithm question. The guy had no interest in being in this interview. He couldn't clearly ask what it was he wanted and he was getting frustrated when I wasn't understanding his asks. "Let's write some pseudo code here" Then five minutes left in the interview "This is fine but I don't want pseudo code, please write functioning code here". Mind you he still hasn't told me what the input was. This last round was one of the top two worst interview experience I've ever had. It really put me off to the company. On the bright side, The recruiters were quick and friendly.
