If was fairly easy because it was a right after college interview. General questions were asked and mostly the interviewer talked about what work he did for the company and how new hirea would fit in. Then he asked me about my background and my interests. This was just the preliminary interview before the application was submitted

It was a 1 round interview for that team. They asked about very specific and basic stats and models. My interviewer was relatively relaxed working at home, wearing a white t-shirt.
