Interpersonal Frequency interview questions

Multiple rounds with different members of the company. questions were regarding my experience and very casual every round. They all felt very genuine in their questions and I was under the impression I did well and met all their needs but in the end they passed on me after 4 rounds. There were a lot of rounds and apparently still more to come which I don't think were necessary but they did mention their retention was great so perhaps that was the trick. I wish they had provided feedback on why they passed.

Three rounds of interviews over two weeks. Each team of interviewers was well prepared, thoughtful, and provided key insights on the company. The recruiter was excellent and prepped me at each step about who I would be meeting with and why.
