At my school, they basically interview anyone with a GPA greater than 3.25. They have a first round interview and make their cuts in one day, then have second round interviews, both on campus. They make another cut then invite recruits to a site visit. The site visit was another two interviews and a skills/personality test. They give a few presentations and take everyone to a really nice lunch/dinner.

Questions asked for both rounds seemed to be mainly culture fit and asking about past intern experiences. Interviewers were nice and were happy to answer any questions you had on the role. Though, expectedly the second round was slightly tougher. The questions weren't tough but just the intensity of having to think on your feet.
