Meta interview E3 virtual onsite loop

I had my virtual onsite interviews for E3. Both of my technical interview rounds went well. During my behavioral interview round, which was the last interview for the day, the interviewer started by asking if this was my last round for the day; I responded yes. Then she began asking me questions. My interview ended 7-8 minutes earlier than scheduled. I am unsure if I need to be concerned about this. I believe I answered most of her questions and also asked 1-2 questions at the end about her position as Engineering Manager.
