Addepar Systems Engineer interview questions

I have been told that I would have 5 round of interview but it went till 8 rounds. And Interviewers were least bothered about the answers given by the candidate. And after all 8 rounds (where they asked me for addditional 2 rounds) of interview they mentioned moving forward with other candidates which makes no sense.I have wasted a whole month for the interview process I would suggest not to take an interview with Addepar.
