Penguin Random House Customer Service Representative interview questions

Applied online through their careers website, called by HR roughly 1.5 weeks later to set up interview, In-person interview with hiring manager and an assistant, had to arrange books in the interview room while waiting for the interviewees to show up (personality/behavior test?), they will ask the questions pretty fast so be prepared to think fast and give a quick answer, I got the assumption they were hiring a lot of people at one time (Dec-Jan time frame) so were trying to squeeze a bunch of interviews in the same day. Do not attempt to chit chat or elaborate on your answers.
