End of summer project

I’m approaching the later half of internship now and Im sure a lot of other people as well. We will soon be given a capstone project and Im wondering if anyone can share their experience on what the expectations are. Do they grill with you with tough questions and generally is the capstone like a full pitch you present to the team? I’m just worried because I still get nervous in presentations which I just don’t know why it happens. I’m just sick of myself getting nervous in a final presentation
