Gap Kids Merchandiser interview questions

I was offered a Kids merchandiser position and had two interviews in one day, first interview with HR and second with Boys and Baby merchandiser. The HR lady asked me questions that made me feel uneasy and most of the questions she asked me with a hint of accusation which was very unpleasant. The merchandisers were very nice but also made me question their Job task... I understand MD job description defers from company to company but when they asked me about issuing PO and being in charge of OBdates, I wasnt sure if I came to the right company for interview.
