Opinion on my Interview

I had my final interview with the Managing Director. He mentioned that it’s between me and one other candidate. This was the third and final round, after interviews with a VP and a junior team member.
The interview itself was very straightforward. He asked me to introduce myself, then asked a few logistical questions (where I live, when I graduate, and when I could start). After that, he mostly gave me time to ask my own questions.
The whole interview lasted about 15–20 minutes, although the invitation email didn’t specify a duration.
Would you consider this a good sign or a bad sign?
They said they’ll get back to me on Monday.
