I interviewed with several different members of the team, as well as the HR coordinator. They focused a lot on what I had learned from previous projects - they weren't applicable to the position, but they wanted to know about my work process. Additionally, there was a technical interview where I had to debug some code in either C++ or Java. They weren't necessarily looking for you to fix it, but they wanted to see your thought process and get a feel for your comfort with these languages.
