I got interview notification 2 hours later after I handed in my resume at the collage job fair. The interview was arranged the next day and took about half an hour. Questions were almost based on my resume. Network protocol basis were also asked. For intern, they just need one interview.

Interview consisted of introductions, behavioral questions like "why do you think you would be good fit". Then, there was a resume explanation time where I had to explain in detail the parts of my resume. After this came the follow up questions. I was asked questions about my resume, technical details about my projects.
