It was a panel interview, just one interview took place with 2 engineers that I was going to be working with. It was a hour long, with mostly behavioral questions.

Spoke with a campus recruiter and arranged an interview at Hope Creek Power Plant. (They reimbursed me for travel expenses) Was interviewed by two people. They do not ask any technical questions for a internship/co-op position. The interview consisted of three behavior style questions that could easily fit the STAR method. They had a big list of questions and asked me three random questions. After the questions, I just told them about myself and went over my resume. It was a pretty laid back interview.
