If an interview is set for an hour, and the questions and answers last 35 min, is it up to you to make it longer as the job seeker?

Aftee the 35 minutes we were just talking about diff topics like traveling, what the team was like, past experiences,etc. I felt like that could be a good sign but the fact they didnt give me a definitive answer on when they are going to make a decision, and didnt give me their email if i had questions, ,was a little discouraging
