For my internship, the interview process was really easy compared to full-time interviews. I only had one interview with an HR person. She basically just asked why I wanted an internship there, and why I was qualified based on my college major. Later that day, I had an offer letter for an internship.

Had a basic phone interview, and then went for an in person interview where I had to do a written test and then had another interview in person with the person who would be my supervisor.
