Bunch of personality questions. Also a lot of them just talking about the position and the requirements. Few general behavior questions but none to be concerned about. More of a conversation about resume and ambitions than a formal interview. Very straightforward and nothing to worry about. I conversed a little via email with the interviewer about some questions I had before deciding it was not for me. My best advice would just be sound excited and knowledgeable about the company. If they called you they must like your experience so one should not fret too much.
