The person I've interviewed with was quite explanatory. She told what they need and how the department works in detail. At the end of the interview she added that If I had any questions, I could ask the HR representative for her e-mail address ask my questions. Despite this, when I request her e-mail from HR I didn't get any response from them and even though I somehow found her email address, she (the person I interviewed with) didn't answer. They are not communicative people, and communication is very important in the workplace from the very beginning.
