I appliyed in a job fair at my university. The process took 3 weeks. A interview was scheduled by the recruiter a week after the fair. I had two back-to-back technical interviews. The first interviewer preferred me to write the answers on paper and was more strict. The second one was more relaxed and let me use the board.

It was fine but nothing special. Typical questions for an intern applying for an internship program. You wouldn't be surprised. Come with good questions. That always helps. Worst case scenario you don't get it.
