The person who was going to be my manager called me and we had a short 20 min conversation about the role, why I wanted to intern and what each of our expectations were

First round was with someone from HR. Pleasant and short conversation about how I learned about MATTE, why I wanted to intern at MATTE, my availability, etc. Second and final round was with someone from my department where I talked about my projects. Overall, everyone was very friendly! Whole process took about three weeks.
