Summer internship interview is relatively simple. The supervisor will give a phone interview, talk about the project and your work. Mostly introduce the current and future work on their side and your job responsibility. They will notice the challenges and hard part on your past projects, and also focus on your real contribution to the projects.

Need to have a presentation to demo the related capabilities. Then it is the Q & A process. It is based on the group request. People that interviewed me were very nice.
