Chilled out interview with basic interview questions. The cool part is that you get to meet 3 different people, in my case - manager, senior campaign manager and VP of operations. This gives you a feeling and a good understanding of a company's culture and how everything is being operated. Other than that, interview was more of a casual type, telling about yourself, previous experience, describing in what kind of environment you would like to work (make sure to mention fast paced!)
