Only asked me one interview question

I had the easiest interview of my life. The only question the manager asked me about is why I left my last job. She had a copy of my resume plus a three page written application she had me fill out when I got to the interview. The interview was about 45 minutes of the manager telling me what the job entailed, her management style, the office culture, benefits, etc. At the end, she asked if I had any questions. I looked at the list I had in my notes, and she had answered all of them except about training so I asked that and she responded. A couple points: I am way overqualified for this position on paper, but I explained to her in an email prior to the interview and on the application that I am making a career change so was looking for entry level. Secondly, she made it clear she wanted someone next week (which I was okay with). She said she would make a decision today or Monday, and there was no communication today. Also, this is a large old family company, and they seem laid back. Has anyone else experienced this? Has anyone given an interview like this? What was the result or reason? UPDATE: I got the job!
