Snowflake Manager, Account Development interview questions

I met with the hiring manager for the position. He asked pretty standard questions for the role. I was a referral from a Sr Leader in Sales at Snowflake and the initial interview was set up quickly. I received very positive feedback at the end and he said I'd definitely move forward to another interview. A week later a received a decline from someone who I believe was his boss. There was no feedback about why I was being declined and what was lacking which I would expect since I received positive feedback at the end of the conversation. It would have been a decent experience had the response to the declination been different from the leaders within snowflake. I reached out to both the interviewer and the boss to get more detail and they did not respond at all.
