Is a short interview a bad sign?

I had an interview for a job I really want on Thursday of last week. It was super conversational to the point that I didn’t feel like I talked much about my career but more of just who I was. The woman was very nice told me a ton about the job and asked if I had any questions. It was so fast that I didn’t really have much to ask but managed to think of one question about the travel with the job. It lasted 15 minutes in all and at the end the interviewer even said, “That was a super efficient interview” I followed up at the end of the day thanking them and expressing my interest. I know I could still hear back today or tomorrow but I’m worried I screwed something up with how fast it was.
