I received an email, inviting me in for a in-person interview with two days notice. The panel interview consisted of five individual 1:1 interviews with three supervisors and two associates from the department. I met the first interviewer at the lobby of one building and she brought me up to a conference room in another building. The other four interviewers came and went from the conference room, and I just stayed in there. The interviewers were very friendly and the work environment is very casual. My interview lasted a total of 3 hours. They asked questions about my past work experience and several behavioral questions.
