Navan Product Manager interview questions

A recruiter reached out for the position and we set a schedule for the following week. The initial call was very promising and I really like how it went (conversational). After the recruiter call, we immediately scheduled the call with the hiring manager. I talked with the hiring manager and he asked me a product sense question. I really came up with great product solutions and listed pain points based on the prioritized user segment. I structure my answers and felt like I did good. However, I couldn't pass the second round and no reason was provided why they decided not to move forward with me.
