Asked mostly behavioral questions, i.e. describe a time you worked in a team and had to overcome a challenge, and describe a time where you had to come up with a solution on your own to a difficult problem. Mostly STAR based questions. The interviewer wanted to make sure that I was not just technically competent, but capable of interacting with others. I made it a point to emphasize how much I liked working with people and I think that put me in good stead. Very friendly interview, I was told a little bit about the position and contacted within a few weeks for a final interview on site.
