Fairly quick and simple. Some questions were ask about prior job experience and how I usually handle obstacles. Handled it quite smoothly and I was given the role as an R&D intern

I first talked to a recruiter at a career fair, and I applied online on my university's career center site that night. Within a few days, I received an email telling me that I had an interview. About two days before the interview, I received a call asking if I could do a phone interview (which I did the next night). The questions asked were more behavioral questions ("Name a time where you applied something you learned in one of your classes outside of class." or "Give an example of a time you took a risk, and why you took it.") After the phone interview, I was told that I was to be interviewed in person the next day on campus. This interview seemed quite casual. The interviewer did not ask me much of anything, and mainly explained to me about what Abbott was like as a company. I received a call about a month later telling me that I was hired.
