It's a brief 30 minute phone interview with the hiring manager. There is no technical questions. We first talked about the position and what kind of modeling/roles will be expected from this position. Then I introduced myself and described previous projects I have worked on. It was a nice talk but apparently the company is looking for a full-time, but I am looking for an intern position.

1 interview in my Grad School + 5 on-site interviews. The interviews were not very technical, but I had to know perfectly how to describe the projects I did, what algorithm I used. I said almost the same thing again and again, because the 5 interviews were not very different.
