Still nervous even after interview !?

So I had an interview last Thursday for a job that I desperately want! During the interview, the CEO said I did well n I was what they were looking for but he wasn't promising anything. He really gave me some awesome compliments n said they will be calling people back for second interviews. A couple of hours after the interview, I sent a thank u note and he responded by saying...."it was a pleasure to meet u today. Ur positive attitude n desire were impressive. Looking forward to meeting with u again in a few weeks". Does this mean I have a second interview?
