They came to my college campus, and they are very focused on quality leadership experience, GPA, and achievements. I was given a first round interview. Then they called me back for a second round interview + aptitude, skills, & personality assessments. Then I was selected for a final round interview, where I was flown to the office selected for me. There were 3 interviews for the final round. They try to keep interviews casual, though professional, so that you feel comfortable being yourself. You can be a very intelligent, accomplished candidate and not move forward or get an offer, simply because they are looking for people who fit the culture and/or who they can picture themselves working on a team with.
