Very Positive Interview Feedback… and got rejected.

Interviewed for this tech company in the US. Was told that all the interviewers (total 3 including a dept VP) gave a very positive feedback and to stay tuned as they finalize next steps reviewing all the candidates at this stage. VP had even told me that he really enjoyed the conversation with me (at the end of the interview). Then got rejected after a week.

I am not sure how do I improve from here. Feels like I did give it my all. Is it that the interview feedback wasn’t very truthful? Not sure.
