Decisions interview questions

I was contacted by a recruiter, then had an initial interview with said recruiter. I was passed to the next round with the hiring manager for second interview. Hiring manager was positive and engaging, transparent with expectations and that while I have a wealth of knowledge and experience, they were likely entering a different sector than my experience aligned with.

Interview went well but not sure why i got rejected. first round be internal screening then we need to develop a flow later we get to HR interview. I got rejected so i am not sure if their be any other rounds
