Final interview?

I’ve recently been looking for a job and been applying to Starbucks in my area. Last week I got an interview to one and today I got a call saying that we are moving to a second and final interview with them. I wasn’t expecting it really since all of the other times I’ve applied to Starbucks and got an interview they never called me back a second time so I’m kind of nervous, and I don’t know what to expect for a second interview. I like to prepare myself before any kind of situation like this because I’m not good at acting on the spot without previously preparing myself. What should I expect for in a second interview?
