Even in same country (Turkey) at different companies, there are lots of culture difference. Yes! The differences between companies about culture. Somes are kindly, respectful, good-humoured but the others are really serious and straight face. They are just talking like robots. And they are as same as your sample; they asks the question and they want you to reply in a couple seconds. If you don't reply it quick they would have a bad preliminary impression that you are not the person they are asking for. But in the other hand there are several HR's they are good-humoured. And they are not interveiwing with you. They just have a chat and give a firm hand-shake... Therefore I really understand you well
