I was in a room with 3 other people who took turns asking me various questions. They had a huge list of questions and would randomly pick from the list so the questions asked are not the same for each interview. They do ask a good amount of behavioral questions related to your resume and some tricky questions to trip you up. After the initial interview, they had a morning on-site interview process where each candidate would have 3 one-on-one interviews and lunch. After the on-site interviews, they would make their selection for the internship.
