Initially, I was asked a lot of technical questions involving languages I had experience developing in, IDE's and other tools I'd worked with, and to show examples of my previous web application work. When I transitioned to a BA interview, I was asked more about meeting with clients, resolving issues with clients, apps in general (what was one thing I would change about an app of my choice), and other app-related questions (bugs I'd ever noticed, how certain apps maintained their security, etc.).
