Very lengthy interview went through several managers... You go through about 4 interviewers that is scheduled, allow a few hours to do it. I was taken in to get interviewed the last one out of the group of people. They each have a an entire list of questions to ask... Very by the book... By the time I got to the last manager I practically ran out of the answers, and was mentally wiped out. I got the job. Bottom line practice makes perfect, study your questions and answers, be honest don't lie
