CarGurus Principal Javascript Engineer, Mobile interview questions

I was contacted by a recruiter from CarGurus on Hired.com. First round was a Reactjs coding round on an online IDE. Second round was 5 hours spread over 2 days with 5 different people(1hr each). The recruiter and interviewers were friendly and easy to talk to throughout the interview process. However, the feedback I got after the process was vague and unhelpful. Something like "Nothing that you did wrong, but they are just moving forward with other candidate". I completed all the coding rounds with time to spare for follow up questions. Interviewer in the first hour of second round could not frame here follow up questions clearly or did not bother rewording them so I can understand what is she looking for. She kept asking the same thing a few times and when I explained alternate approaches and asked if I should modify my code each time she asked me not change it since I have something working. I was also informed that I am being considered for a few different positions by the hiring manager in my last interview but no follow up on that either. Overall the interview process was smooth and the interviewers as well as recruiters were helpful but not even providing 5 mins of meaningful actionable feedback after 6 hours of interview feels disrespectful of candidates' time
