First had interview on campus. General interview questions, where do you see yourself in 5 years, etc. First interview was relatively straightforward. Second interviews were in office, one was a case interview, another was a behavioral interview. Between the interviews all of the candidates were sat down at a group table to speak with multiple current employees. During the case interview there were two questions, one was a brain teaser and another was a case question from the interviewers past experiences. The interviewers kept all of the notes I took during the case interview. They also were keen to see/keep a paper example copy of a project I had worked on in the past.
