Was encouraged to apply online through college career fair. Received email and phone call to set up an interview with them about two weeks later. Heard back about a month after initial interview. A lot of straightforward workplace behavioral problems that HR departments typically ask during interviews. Take it easy and you'll be fine.

Applied online for a different position, but was given an interview for this internship. Expected a more formal interview, but it was fairly casual in structure despite technical nature of topics covered.
