PPD interview questions

I submitted an application online and had a phone interview within a couple weeks. I had an in person interview a week and a half later and met four supervisors for the department. They had a number of formal questions each but were overall very laid back and seemed genuinely interested in my background and what I was looking for in an employer. I was offered a position within a few business days, but it did require a background check, credit check, and drug test first.
